To add and subtract numbers within 100 [2.NBT.B.5].
Add and Take Off is a Grade 2 card game for adding and subtracting two-digit numbers within 100. Players use cards to build two two-digit numbers, add them, then create another two-digit number to subtract from the sum. Because the numbers are assembled during play, students work with place value as well as computation.
Use it with partners or a small group when students need practice moving between addition and subtraction in the same problem. It can reveal whether they are keeping tens and ones organized while calculating mentally or on paper. Generate teacher-ready lesson support for Add and Take Off with a free Find a Math Game account.
