Easter Egg Symmetry (+ Bunny Tangrams??)

Last fall, we made symmetrical masks, modeled after some found on Mathwire. I thought it would be fun to do something similar with Easter eggs this week. We began by reading Magic Mirror Tricks, looking at the symmetry in the pictures.

My 8yo enjoyed using punches to decorate his egg. He worked really hard to make it symmetrical, agonizing over the fact that "it might be 100th of a millimeter off, Mom!"



At first, I gave my newly 5yo some cutouts and helped him with the symmetry. In time, however, I faced up to the inevitable. He was having entirely too much fun with DECORATING and could have cared less about the symmetry involved. That's okay. We're all about fun here, too! :)

Check out a few more of our symmetry lessons!

Or try making some Easter bunny tangrams. (What will people think of next???)


We're linked up over at A Mommy's Adventures: stART. And don't forget to check out all the posts linked to Math Monday! What a lot of great ideas to explore.

Yo, Millard Fillmore!

In honor of President's Day (U.S.), here's a little book that we're having fun with...

Yo, Millard Fillmore! uses a series of cartoons to teach the names of the Presidents (through Clinton, btw) in order. Although we're not taking the memorization part too seriously, it's fun to see just how many we can remember using the comic book mnemonic tricks. Even more, I enjoy the trivia about each President, highlighting interesting facts about each person. [Note: although at first glance the book appears out-of-print and $$$, it looks like there are a lot of used, inexpensive copies.]

Math App Saturday (#16 DropBrick Christmas)

While it's not Saturday anymore, I've got a fun, free app for you. It's sorta math related in that you have to figure out some balance/architectural issues as you go...

On DropBrick Christmas you need to clear boxes below Santa in order to have him land safely on the platform below. I was reminded of how entertaining this can be when we sat through a two-hour-plus music concert last night without an intermission. My 8yo and I played it a lot! ;)

Looking for more free, fun, education-related apps? Check out the entire series.

Alternative to Christmas Wrapping Paper

After Christmas morning, my living room is not littered with paper. It's littered with pillowcases and ribbon.

For years, we've avoided purchasing wrapping paper. Although frugality usually tops my reasons for not buying something, this time it has little to do with it. I simply hate wasting that much paper. It literally turns my stomach to see all the garbage (and yes, even piles of recycling) that line our neighborhood street after Christmas. I hate the thought of discarding something that has seen such minimal use.

So every year we get the pillowcases out of the linen closet and dig through a bag of ribbon I found at a yard sale. If an item shows through the pillowcase, we double up the fabric or box it prior to wrapping. If an item is truly too large for a pillowcase (which rarely happens with a low $ limit per family member), we put it in a box or a large popcorn tin (also saved from previous years). For small gifts I reuse wrapping paper we get from packages outside the family. Or we use the old standby, newspaper comics.

It's just as fun to "open" a pillowcase as it is to open paper. Perhaps more fun. You can't hop around in torn wrapping paper after all the gifts are opened! :)

Advent Calendar of Math Games

First, found NRICH, a very cool website with "thousands of free mathematics enrichment materials (problems, articles and games) for teachers and learners from ages 5 to 19 years."

Second, noticed that it contains an Advent Calendar with a "mathematical game for each day during the build-up to Christmas." You just click on the date to see a new game. Most of them are on-line, interactive. Fun stuff!

Graph Your Halloween Candy!

Jedi Master say...

"A good Jedi must always graph his Halloween candy before eating it. May the force be with you!!"







 Fastest graph, EVER! ;)

Jedi Masters need chocolate, too. Think the Jedi would notice if a piece of his graph disappeared? ;)

Children's Math Book Reviews

With a sick student (or two) we've been doing a lot of reading. What incredible affirmation as to the power of math combined with literature! Little Student made connection after connection. So on our "no school" day, we learned a TON. (Or is that 2000 lbs?) Here are our top picks:

My opinion about The Wishing Club; a Story About Fractions by Donna Jo Napoli, totally changed. When I read it alone, I wasn't terribly excited. When I read it to my student, his enthusiasm was catching. In the book, siblings, ages 8, 8, (twins), 4, and 2, wish on a star. Over several nights they discover that their wishes are granted in fractions, determined by their ages: 8yos get 1/8, 4yo gets 1/4, 2yo gets 1/2. My student quickly understood the concept of fractions, exclaiming after the second page (which shows four 1/4ths make 1), "then one penny is 1/5th of a nickel!" In the story, the siblings put their wishes together to make one whole wish and get the wish that all of them want. [Concept: fractions]

My current student and I have not talked much about probability. The book, A Very Improbable Story, by Edward Einhorn, proved to be very effective when introducing the topic. Ethan, the main character, wakes up to find a cat, "Odds," attached to his head. An improbable event, indeed! He can only remove the cat if he is able to win in a game of probability. Several games are played and the odds of winning are thoroughly discussed in each scenario. By the end of the book, my student talked about the odds of Ethan winning or not winning the games. He also got a good laugh at the question at the book's end...what's the probability that you will open the book to a page with a picture? (Odds: 32 in 32 or 100% chance.) [Concept: probability]

In Equal Shmequal by Virginia Kroll, some animals witness children playing a game of tug-o-war and set out to play their own game. It quickly becomes obvious, however, that they have a problem making the sides "equal" with five animals competing. But even when the sides have equal numbers, the groups still aren't fair because the weights aren't equal. They set about figuring out how the animals' weight can be evenly distributed by balancing on a park teeter-totter. But when the bear is distracted by honey, they learn that equal effort is also important. Super cute. [Concept: equality]



The Candy Corn Contest by Patricia Reilly Giff is part of "The Kids of Polk Street School" series, chapter books for young readers. This book has a reading level (R.L.) of 1.9 (first grade, ninth month). I read it aloud to my sick 7yo. The story captivated him and he would read ahead over my shoulder and then hide his eyes because he was nervous about the events.

The main character, Richard, would like to guess the number of candy corns in the Thanksgiving class contest. Problem is, each guess is earned by reading a page in a book and Richard is not a good reader. Left alone with the candy jar, temptation becomes too much and he secretly eats several candies. Then what is he to do? He learns the teacher has written the number of candies on the bottom of the jar. Should he change the number? When the class ultimately shares the candies, the reader can think about division. [Concept: estimation, briefly division] Easy reader chapter book.

365 Penguins by Jean-Luc Fromental is an oversized picture book that provides many opportunities for problem solving. Each day, beginning January 1st, a single penguin is delivered to this family's home. After two months they have 31+28 penguins. Then they organize them into 4 groups of 15. But yikes! What about the food? They eat 2.5 lbs of fish/day at $3/lb. By the 100th penguin, it's getting expensive. They decide to arrange the penguins like eggs, in dozens. 12 boxes of 12 penguins. Later, they're stored in a cube shape = 6x6x6. By Dec. 31st, they have 365 guests. At last, Uncle Victor, the ecologist, arrives to transport the penguins. But, on January 1st, another BIG box arrives. Uh oh! [Concept: problem solving]
