Strategies for basic addition and subtraction facts
In this video I show several strategies for learning the basic addition and subtraction facts: finding all the possible sums for a certain number; e.g. for 6, these would be 0 + 6, 1 + 5, 2 + 4, and 3 + 3; writing out all the fact families where the sum is a certain number; the 9 "trick"; 9 + 7 is the same as 10 + 6 (9 wants so badly to be 10 so that it "steals" one from 7); doubles and the accompanying addition facts; number rainbows and how to use them to practice subtraction; a structured drill for addition facts.
