Number Sense Activities for numbers 1-10 takes your kids knowledge of numbers and how they're represented and puts them in this fun, friendly and somewhat competitive timed format.

Get out a stopwatch (or the stopwatch on your phone)! Ready, set, GO! Kids fill in the number sense worksheets or laminated pages as fast, but also as accurately, as they can. You can have your kids beat their own best time or have a little friendly competition with their friends. Or you can just have them fill in the number sense activities sheet without being timed. Great for number of the day or number of the week! No matter how you approach it, your kids will get in some great number sense practice.
