- What is the Golden Ratio? A boy thought a museum had it wrong, and got in the news for correcting them. Really, they used the less common version of the ratio, still right. Read about it at Sense Made Here.
- Jonathan Halabi blogged about how crazy the scores on the NY common core math tests are. I wonder how other states report scores.
- I've been wondering whether I can use the principles of storytelling to improve my teaching.
- I wonder if I can modify any of these math movement games for kids, so they'd work well with adults students.
- How can we shift math education from memorizing to problem solving? How can we help students learn problem solving? (NY Times article)
- I've figured this out before, and the answer is even somewhere on my blog maybe. But I am once again stuck. Flipping coins to one side without looking... (on a Math Riddles blog)

I'll be leading a Math Jam for eight days just before Fall semester starts, helping students prepare to succeed in Beginning Algebra. My eight topics:

- Number Sense
- Fractions
- Negatives
- Algebra
- Percents
- Graphing
- Slopes
- Problem-Solving

For fractions, I plan to do a bit with Egyptian Fractions. Here's a site that looks good for that. I looked at the Beast Academy site to see if they had anything good. I found 5 things I liked: one game and two puzzles using the area meaning of multiplication, one puzzle on ordering of decimals, and one game like Taboo for communicating about shapes.

The coin flipping puzzle was great. Listening to my kids discuss it gave me the idea to identify possible states, the different moves, and the potential outcomes of applying each move to each state.

ReplyDeleteAlso, try the puzzle with only 3 coins!

Here are some other ideas for extensions.

Thank you, Joshua! This is why I blog - I love connecting people with good ideas. Your post makes me realize that this has a different sort of solution than the puzzle it reminds me of. You might like that one too. It's #7 in this Pi Day Puzzle Party post.
