This activity I made to help my students with not only their number sense, but addition and subtraction as well. It's a great tool to use to really have the kiddos think in terms of increasing by 10 or 100, and decreasing a number by 10 or 100. I have included 2 different worksheets, that offer a variety of numbers up to the 900s. I also thought about the challenging and critical thinking task of finding 10 less when there is a 0 in the tens place (such as: 405). These worksheets you can utilize whole group, small group, or independently depending on the needs of your kids. Hope you enjoy!!
