Beating the Combo
mixed operations · mental addition and subtraction within 20
To add and subtract within 20 using mental strategies [2.OA.B.2].
Beating the Combo is a Grade 2 mixed-operations game for mental addition and subtraction within 20. Players draw number cards and roll a die, then use the numbers and the game’s operation conditions to work toward a successful combination. Because the values change from turn to turn, students have to choose and carry out mental strategies rather than repeat one fixed fact pattern.
Use it for partner or small-group review when students need flexible practice moving between addition and subtraction. Listen for strategies such as counting on, making ten, using doubles, or thinking of subtraction as a missing-addend problem.
