This is an activity where students roll two dice and put items (pompoms, ornaments, bells, any manipulative) on the Christmas tree. I will usually colour coordinate the dice to the 2 different items to make it easier for the students to separate. Once on the tree, the students will count and write the number of each item at the bottom of the page and add them together.
This activity is in French and in English. It can be printed on coloured card stock to give it extra Christmas flare, and laminated for reusability.
