These BOOM CARDS provide fun practice with relating sums with 8 or 9 to sums with 10 and help kids understand models. The cards are self-checking digital pages hosted by Boom Learning. The 1 and A stand for Grade 1, Algebraic Thinking domain. For this activity, students must match two expressions such as 8 + 4 and 10 + 2, or match a model to the addends. The cards shown are the same as in the printable Multi-Match cards, 1A: Adding with 8 or 9 by Making 10
The "1A" in the title stands for Grade 1 Algebraic Thinking.
