Mr. M.

Use this hundred chart and decoder to show students the patterns that exist in the hundred chart. It works by students placing the star on the number in question. The decoder (use printed transparencies or cheap paper (too thin)) to see what ten more, ten less, one less, and one more than the number is. Students love that they can figure it out by themselves!

Looking for a self-correcting way that keeps kids engages while teaching the all important base ten system of place value? Here it is. Students love the varied ways that base ten is provided (sets of bowling pins-10s and single pins-1) There's even dimes and pennies. I've included instructions on the first page, so it can be sent home for extra practice, too!
