To add a two-digit number and a one-digit number
SLAP IT - 2 DIGIT BY 1 DIGIT ADDITION is a Grade 2 speed game where three cards create an addition problem. The first two cards form a two-digit number and the third card is added to it; students race to calculate the sum, slap the cards, and say the answer aloud. A wrong answer opens the round to a steal from another player.
Use it in a small group when students are practicing two-digit plus one-digit addition mentally or with efficient strategies. The fast reveal encourages students to look for place-value shortcuts rather than recounting from the beginning.
