Number sense activities are so important in kindergarten and preschool math. It's important to give kids a variety of counting activities to gain automaticity. I love stocking up on math center ideas for kindergarten. That way you can change things up, but keep working on the same concepts all year. This fun set of Free Back to School Puzzles for Counting to 10 are a great way to ease kids back into school. They are easy to prep, so you can focus on settling into routines, bulletin boards, word searches, and all of the other things as you kick off the school year!
