This activity I created to help my students with their number sense abilities for December month. It's a great tool to use to really have your kiddos think in terms of number order and sequencing, as well as increasing by 1, and decreasing a number by 1; as well as increasing by 5, and decreasing by 5; as well as increasing by 10, and decreasing by 10. I have included 3 different worksheets, that offer a variety of numbers up from the 10's to 90's...all 2 digit only. These worksheets you can utilize whole group, small group, or independently depending on the needs of your kids. Hope you enjoy!!
To help you differentiate, I created the exact same version (theme/clipart) but with 3 digit numbers with high, more challenging More/Less increments: CHRISTMAS Number Sense: Harder Version
