NUMBER RACE
addition · mental addition with sums below 20
To add numbers mentally - sums below 20 [2.OA.B.2].
NUMBER RACE is a Grade 2 mental-addition game that uses dominoes to create sums below 20. Players draw two dominoes, add the total dots mentally, say the full addition sentence, and color a box above the matching sum on their game board. Accurate sums gradually build a race toward the top of the board.
Use it for partner or small-group fluency practice when students are ready to add without writing each calculation. The dominoes provide a visual quantity model while the spoken equation connects that model to symbols and number language.
