Roll Add & Cover is a great center activity to practice addition facts and can also be used to practice writing addition number sentences. It is designed to be played with a partner, but could also be played independently.
Included with you purchase are three different game boards and 1 recording sheet (both color and black and white). You will also need 2 6 sided dice and counters (or dry erase markers) to play.
I would suggest printing these game boards on cardstock and laminating, or gluing them inside of a folder and then laminating for a folder-game activity. I use mine in plastic sleeves with dry erase markers.
