Great for a center activity! Laminate each of these pages and cut out the turkeys and the feathers. There are four turkeys: one blank one, and three marked 10, 15, & 20. There are blank feathers to make your own number sentences, and pages of number sentences to use for making 10, 15, and 20. The number sentences come with either two or three addends, and there are number sentences equaling 10, 15, and 20, as well as number sentences that do not equal 10,15, and 20, but are close. Mix up all the feathers and have students arrange 6 feathers behind the turkey. Students can either slip the feathers behind the turkey, or you can add Velcro to the feathers and turkeys so students can attach the feathers. Six worksheets are included. I hope you enjoy this festive Thanksgiving activity!
