The website that is linked to the title of this post has directions for making designs on a 100s chart. It is a great activity for number recognition, or you could give the directions for +1, -1, +10, -10, etc.
I think I will go to the craft store and buy some “jewels” with a flat side so that they can make the designs with those. It seems like a really fun way to practice a lot of math skills.
I found something really fun on Apples4theTeacher
It is so cool! Some of the kids can play on the computer! This is a link to a 100s chart coloring page! You can choose different colors, touch the crayon to the number on the hundreds chart and click on it to make it change color.
Too much fun with a 100s chart!
