Looking for a game to help celebrate the First 100 Days of School? Try Square Jigsaw" from the University of Cambridge in which students are challenged to build a 100 square by fitting puzzle pieces into a grid.
I love these free colorful hundred chart puzzles! Great way to help kids build number sense and practice 10 more, 10 less, skip counting, patterning, counting on and more. It's a new way to use number chart.
