Lattice Multiplication

I'd inadvertently downloaded a lattice multiplication app a couple weeks ago and thought "Huh?" when I looked at it. But yesterday I watched the Khan Academy video on lattice multiplication and now I'm sold!

I'd never heard of it before, but I think it is a really nice way to do multiplication of multi-digits. Better than remembering the 0 in the standard way--so nice to do all the multiplying then all the adding. Plus it's kind of fun. It feels like it is too tricky to actually work, but it does.

Term B, Week 2 Report

Oh yeah, I'm on top of things this week. We actually ended a little early today because Noodle had a friend come over so I decided "socialization" (snerk) was more important than more science (which we've already done 2x this week).

Language Arts
Reading
Noodle is nearly finished with the Yesterday's Classics First Reader. It has been a good one and she's enjoyed it. Three days this week, though, she read from Ruby the Red Fairy. It is a bit above her comfort level and is a beginning chapter book, but I wanted to find a book she'd enjoy reading and that would show her that YES she CAN read chapter books. If I'm there with her to help her when she gets stuck on a word (only so she doesn't get too confused trying to decipher the meaning when the words are wrong), she can maintain a fairly decent pace and enjoy reading the book. Earlier in the week we agreed on a "4 page/day" assignment, which seemed a little skimpy to me but I didn't want to push her too much, and today she was so into the book she read 10 pages! She just kept saying, "I have to find out what happens next!" and, "Sorry, Mom, but I just have to read one more page." I was so delighted!

She also read some advanced BOB books that we hadn't done before. And she picked up the Big Dog, Little Dog book I'd read to Spud yesterday and read it all the way through. Since she has not been a self-motivated reader, I am tickled every time she chooses to read something or read more on her own.

We (Noodle & I) also played the Y Not? game from Happy Phonics a couple of times this week after reviewing the Y-ending pages in Phonics Pathways. The first day we played it, she loved it and we had to play it three times. I was happy to do so.

Grammar
We learned pronouns this week. "A pronoun is a word used in the place of a noun."
I, me, my, mine
you, your, yours
he, she, him, her, it, his, hers, its

we, us, our, ours
they, them, their, theirs

She did really well and seems to grasp the concept without much difficulty. Next week we'll do a review page (from the Worksheet generator link I posted yesterday) to see if it is clicking. I think it is.

Spelling
Noodle was struggling with the words could and would when she would encounter them in her reading, so we did a list of regular "ou" words (i.e. proud, loud, round, found, out, etc.) and the three irregular words could, should & would. She got 100% on her Spelling Test today, but then in her reading stumbled over could the first time, but got it in subsequent encounters. Being as visual as she is, I think she has to see the words a lot before they are solid in her mind. My goal with spelling is to reinforce the rules as well as revisit some of the ones we may not have covered too solidly in the past.

Spud spelled some words from some pictures cards, but he wasn't too excited about it. I am planning on taking a break from really requiring him to read anything for a while. I wish I had some sort of handbook that would tell me the best way to motivate this little guy to learn. Te thing I have to remind myself over and over again now is that he hates to do things he can't do
well (as judged by some unknown standard in his mind), but he likes to do things he CAN do well. He hates to be on the spot for knowledge he isn't confident about. So we are shifting our preschool approach to reading books and doing activities.
One of Spud's favorite books is Big Dog, Little Dog, so for our first day of "new" preschool, we read this book and then he colored pictures of items from the story either red or green, depending on whether they went with Fred or Ted. I cut them out for him (because he didn't want to, for who knows what reason) and he glued them on. I freehand drew the dogs, and was pretty proud of myself.

Our agreement was that we would do two activities of my choosing every day (in addition to his computer school) and then we would do "Fun Time," where he gets to choose an activity to do with me for 15-20 minutes. We only started Thursday, but both days we built towers/buildings with blocks in the playroom and then crashed our matchbox cars into them. It was surprisingly fun. I have to keep reminding myself that learning stuff (reading, numbers/math, etc) isn't a race, and it really isn't going to affect them in the long run if they master reading 6-12 (or even longer) months earlier or later. What WILL matter, though, is the attitude they have about learning. Spud is a hard kid to teach, but he's a pretty easy kid to have fun with. So I'm hoping that working on our relationship will help him feel happier and more capable.

Writing
Noodle is doing really well with Writing With Ease, Vol. 1. I like that the lessons are grab-n-go and typically take less than 15 minutes to complete.

History - The Phoenicians
Did you know that the reason purple dye/cloth was so expensive long ago is because it came from sea snails that had to be gathered and boiled to get the dye, and it took a lot of snails to make the dye and it STUNK. Maybe you did, but I didn't. We learned all about the Phoenicians this week. How they lived in land (modern day Lebanon) that was inhospitable to crops or raising animals (due to the whole "no crops" thing), so they became totally awesome goods-makers and traders. They were the first to invent blown glass! They also had the first alphabet and made really nice furniture from the cedar trees there. They set up colonies around the Mediterranean. For our activity we made "Phoenician bread," which is known today as pita bread. No, I don't know if it is exactly the same, but it was one of the suggested activities in our book and we did it. The bread is delicious, by the way. I think we'll make it again sometime. (And I had to include these pictures of the kiddos enjoying the bread this morning!)


Math
Noodle started subtraction this week. She actually did a bit of subtraction in the Primer book last year, so it doesn't seem to be giving her any trouble right now. I suppose we could move faster through the Alpha book, but I feel okay at our current pace and I like that she is getting these basic math facts down solidly. From everything I've read, staying at our current pace she'll be plenty caught up by the end of elementary school. Also, I'm considering doing math through our longer breaks (Christmas & summer) which would help us keep making progress. Ever since I instituted the sticker charts for doing her math work, her attitude has been a lot better. I will say again, incentives definitely have their place! I also found my old addition flashcards so we did those a couple times this week. She earns one Skittle per card correctly answered, as many as she can do in a minute. (She also earns an equal amount of Skittles for Spud. I have him earn Skittles for her, too, some days, to keep it equitable and help them be happy for each other's achievements.) It's great because on Tuesday she got 9 the first minute, 10 the second minute, then 14 the third minute. She wanted to keep trying for more. Thursday she got 14 right off, and tried one more time and had some trouble and only got nine. A book I read about right-brained kids talked about how doing math problems quickly for timed tests can be a challenge since it takes time to visualize the problem, so I'm hoping doing the flash cards will improve her speed in a fun, not-too-stressful way.

Spud can count to 20 very solidly, so we are working on going to 100 now. He will get a "100 Cake" when he can count to 100 unassisted, just like Noodle did, and he is excited about that.
He also does well actually counting objects up to twenty and not just saying the numbers. We are also working on counting by 10s, as I think that will help with counting to 100.

Science - Seas, Oceans
So much STUFF about the ocean to learn. Which makes sense, seeing as oceans cover ~70% of the planet. I had no idea that the Pacific Ocean alone covers 1/3 of the Earth!! Crazy! I think it would be fun to do a longer, more in depth study of oceans sometime, but for now I feel okay with only a week. We did some experiments from the book Awesome Ocean Science. Two addressed how warm water and cold water interact and one was about how the coloring of penguins helps them hide from predators. There were 3 Bill Nye shows to watch (Ocean Exploration, Ocean Life and Oceanography), but we only got the first two done. In addition to our notebook page of drawings/information, I had each kid pick an animal discussed in one of the books we read and we did a coloring page of it. Spud picked an angler fish and Noodle picked dolphins. Spud really wanted a flatfish, but I couldn't find any good coloring pages of flatfish, unfortunately.

This experiment shows how warm water and cold water can take a long time to mix (part of what happens during El Nino). The yellow water was warm and the blue water was cold. Five to six hours after combining the two, they were only somewhat mixed (2nd picture). By morning they had completely mixed. It was really a fun one to do.
For this one, we made a red ice chunk in the bottom of a paper cup and froze it, then put it in a glass of lukewarm water. You can see the cold water carrying the color down, so it demonstrates cold water sinking.

New Activity - Safari
I came up with a new activity for Spud's workbox this week. We call it "Safari" and it means he picks an animal out of our "Wildlife Fact-File" and we read about it, find it's location on the map and then color a picture. This week he picked Desmodus rotundus, the Vampire Bat. We found out that an adult Vampire Bat drinks about 5 teaspoons of blood/day, so we measured out five teaspoons of water and dyed it red. (Though at first we couldn't find red so we did green instead. Then we found the red.) And then the kids wanted to drink the colored water. Sure, they don't really need the food coloring in their systems, but it was a nominal amount and added to the fun.

Music Appreciation - J.S. Bach
We did Vivaldi last week and are just going in order. I'm either going to have to keep rechecking this book out from the library or find another one. (Heck, if I get some $$ I might even buy it.) I really like the one I've been using. We talked about Bach and listened to some of his music. I also got some very simple sheet music from Making Music Fun
It's a little advanced for Noodle right now, but I played it for them and when she has the skills, she can try it. We also colored pictures of Bach. We all did really funky color combinations, which made it fun. Punk Bach.

In other music news, Noodle was assigned to learn a simple version of "We Wish You A Merry Christmas." At first, she was really intimidated by it (it is her first encounter with eighth notes) and said she didn't think she'd be able to do it. Within two days, though, she was in love with playing the song and played it many times a day. Soon she had it memorized. Such a funny girl. I'm trying to teach her to replace her negative "I'll never get it!" self-talk with more positive speeches. Slow going.

Other Stuff

The Hiding Ghosts activity. (They liked it, then Noodle drew one for me to find the ghosts.)




Muffin Tin Monday
Yup, we're still doing it. I've seen some online that are all theme oriented (i.e. apple related or all round). I don't yet have the creative juices for that (nor do I have the money to buy "special" food), but the kids enjoy eating their lunch this way. I have been glad that we often have a variety of cereal opened,as it's good when I run out of other foods.

Fall!
Either Tuesday or Wednesday, we woke up to see that most of the leaves had fallen off our maple tree. The kids had to run out and play (they even raked the leaves themselves to play in!). It was great to watch them and it made me happy that we have the flexibility we do because of homeschooling. Granted, overall there are lots of great reasons for homeschooling, but somedays it feels more poignant than others.

It can be a challenge homeschooling with a baby. His new mobility (he's a great crawler, though still not too speedy) is both a blessing and a challenge, as it keeps him entertained but his capacity for finding the wrong things to play with has exponentially increased. Plus, the diaper changes and naps can interrupt our flow. And it's really hard to do read-alouds if he wants to be held, since he likes to grab the book and crumple or eat it. That said, he's a lot of fun to have around. And he helps us not take ourselves too seriously, and remind us of what's really important.
(Not to mention the awesome power of cuteness.)

Week 5 Report (Term A)

I've decided to letter our terms, so this present week (Week 6) we will finishing up Term A. But here is our delayed report for last week.

Science: Earthquakes and Volcanoes
Watched 2 Bill Nye episodes (one on earthquakes & the other, you guessed it, on volcanoes) plus Magic School Bus Blows its Top. For Family Home Evening, David & the kids built a paper mache volcano, which was painted on Wednesday and finally erupted on Friday (I think). The kids really enjoyed it.


Science: Owl Pellet Dissection
We also dissected the owl pellet we'd found on the river trail. It was neat to see the tiny bones. I was hoping we'd have an intact skull, but we didn't. The lower jaws were really neat, as were the tiny femurs and ribs.




History: The Middle Kingdom of Egypt
I had plans to get some incense to burn (we talked about the Nubians and their use of incense and a lot of gold jewelry), but it didn't happen. Probably just as well as I don't particularly like incense. The smokiness of the aroma gets to me.

I don't know if I have mentioned what we use for history. We are using Story of the World (Volume 1). I like that it is really straightforward, and the story format is nice. You can also purchase an activity book that I think is really worth the money. It has maps and coloring pages, along with review/narration questions and project ideas/recipes. I split ours in half and spiral bound the "manual" portion of the activity book and then 3-hole drilled the remaining pages and scanned them in (which is allowable for use within your own family). So now I just print out the maps and coloring pages as we need them. Pretty nice. There are also CDs of the stories, which I think would be awesome, but they are too expensive for me to justify the price. I know a lot of families really enjoy listening to them in the car and such, which I think would be really nice. Maybe someday...

We did read an interesting book about the Egyptian Gods and Goddesses, though. I was glad the kids didn't clue in enough on the adultery/fornication that was alluded to. Sheesh, what is with those ancient cultures? I guess it is convenient to have imperfect gods if you don't really want to strive too hard with your own morality.

Language Arts
The Happy Phonics set I have has some "flip cards" that change words when you flip the middle vowel. I did these last week with Spud for his reading lessons and he really enjoyed them and didn't grouse at all. So I made five more sets. It was a really great way to get him some reading practice. I don't know why he is so resistant sometimes. Okay, I have an idea why (just hates doing things he doesn't know how to do...I know I've said that a dozen times at least). He was able to fill up his sticker chart the same day as Noodle, so that was happy for both of them. She earns her stickers for doing her math pages independently. I've realized that rewards are a good motivator for these kids. I try not to overdo it, though. We also played The Castle Game from the Happy Phonics set that helps kids identify short vowel sounds in words.

Oh, and he went on an L hunt.

Lion, ladle, letters, ladybug, ladder.

I have to say that I am really pleased with Noodle's progress in reading over the past four months. Last May she was really stumbling over a lot of words , even if she'd seen them many times before. We have done a few things in the intervening months that may have helped. We watched the phonics lessons on The Phonics Page. Then I started working through these Blend Phonics lessons and reading from the Blend Phonics Reader. I think going through these things where the phonics rules are presented so sequentially and individually has likely helped her quite a bit. She's a rule-minded kid. (I'm pretty sure her OCD has a role in that.) We have a few lessons left on the Blend Phonics, and I think we will finish them, I'm just taking a bit of time off to review some of the word sets she's had some trouble with. (I'm using Phonics Pathways a little for the review.)

One cool thing was that I put a Dora early reader book that we've had for quite a while in her workbox. She saw it and said, "Oh, these are really hard. I'm not good at reading these." I told her I thought she'd do just fine, and she practically breezed through it. I think she is really gaining confidence, which is great.

I usually have her draw or color a picture after she finishes reading from her reader, and she drew such a great picture after reading the poem "The North Wind." You can see a little of it in a couple of these photos.Here's Spud making designs on the Geoboards. The kids really like these.



Math
Noodle was doing the chapter about Making 10. One of the activities from the Games for Learning book was a perfect supplement/review of these facts. It's called Pyramid. We are using it again this week for Making 9.

For making 10, take out all the face cards, and make a pyramid of cards (facing up)..., one at the top, six at the bottom, each row overlapping/tiled over the one above. You can only use the "free" cards (the ones not covered by another card) and your extra cards in a deck to make 10s. Try to get the entire pyramid gone. For Making 9s, just take out the 10s. Here's a picture of her playing the Making 9 pyramid.

It might be really obvious to people who play Solitaire, but not being one of those people, it was new to me. She really likes it, though, and it's a great review.

Extras
Spud made a cute hand & footprint lobster from the Just for Fun blog (linked below). I should get a picture taken of it, but I haven't yet. Both kids had fun painting their hands and feet and making prints on the paper. We'll have to do those types of activities again. The blog has a lot of different ideas that involve hand & feet prints, so check it out!

We made stamps for our craft out of small log rounds and foam. We cut the shapes out of foam (also used some foam stickers we had). We finally found our stamp pads today and tested them out, and they work pretty well. It was a fun project, and even Spud got really into it. He wanted to make a rain stamp and a couple of circle stamps, then a fish stamp (with a sticker) for David.


And of course we had Muffin Tin Monday again:
Our other muffin tin is older and less nice looking, so the kids have to take turns having the nicer one. The left column is Desserts.

9s addition facts

We have opted to do the Math-U-See curriculum with the kids. Noodle is in the Alpha book, and today we just started lesson 9, which happens to be 9s addition facts. I wanted her to "get it," but knew that it would be best if it clicked in her brain without me making it too obvious. We watched the chapter intro video, then started doing some practice problems. And it clicked! We drilled the facts by her marching around the ottoman while I tried to build the problem/answer pair with the manipulatives before she could recite the problem/answer, i.e. "Nine plus five is fourteen!" She really enjoyed it and she was fast! We probably did 20+ problems and I was only faster twice.
