Once we returned from our most recent holiday break I felt like my kids needed some numbers to 20 review. I had already exhausted all of the resources that our school provides so I needed to make something meaningful to help increase their number sense. I made the following activities originally just to use in my classroom and not to sell. However, I thought more people might be in the same boat as I. I used these as a center activities. :) Hopefully they help your kids like they helped mine!
-How many more to make 10 worksheet
-Teen numbers practice (numeral, 10 frame, tens/ones) activity/worksheet
-Teen number before/after practice
-Numbers one more/less worksheet
-Numbers two more/less worksheet
-Roll, make, expand, worksheet
-Building combinations to 5 and combinations to 10 worksheet
-Building combinations to 10 (includes part/part/whole and addition equation)
