Multiplicative Thinking

Hello Fourth Grade Friends!

Did you know that you don't have to memorize every multiplication fact? If I forget a fact, I can use what I know to figure it out instead of shooting flames!

I always forget 7 × 6, but I know 2 × 6 = 12 and 5 × 6 = 30. Since 7 = 2 + 5, I can just add the two products of 2 × 6 and 5 × 6 together to figure our the answer: 7 × 6 = 42.
