Want students to be fluent when adding sums of 10? This game can be played whole class, small group, with partners or individually using a timer. Students race against another student or the class to fill in their target sum of 10. The first one to yell "Lickety Split" wins! Play again and again using a variety of game boards, use plastic sleeves and dry erase markers for easy cleanup. I have included a recording sheet and answer key for use in a center. Have fun adding sums of 10...lickety split!
