This Christmas Themed package offers three sets of task cards with 20 cards in each set. This is great practice for addition and subtraction within 20. The collection contains the following:
Set 1 has 20 addition problems
Set 2 has 20 subtraction problems
Set 3 is a mix of addition and subtraction and the orientation is changed to vertical for the problems
There is a student answer sheet for each set and an answer key for each. There is a poster that can be used in a center setting.
This is great practice for students who might need extra drill or for those early finishers that you want to provide with a meaningful review. Extra packs of cards could be given to students for individualized homework assignments.
