Add the Doubles For Google Apps | ||||
Part of the strategies to memorizing math facts is using a good progression. Learn to add the doubles: 2 plus 2, 3 plus 3, 4 plus 4 as that will give a great strategy to learn all the facts to 20. For instance if I know that 7 + 7 is 14 then I know that 7 + 8 will be one more which makes it 15. |
