This week for math my group three ways to solve a math question here is my problem.Use a broad range of mental strategies to solve addition and subtraction problems. enjoy my math
my favorite strategy was tidy numbers if for example if you plus two you have to minus two and for subtraction if you plus 1 you plus 1 because your taking away the numbers you added would get taken off anyway. here is a question 67+28=? so I would plus two on 28 two make it 30 but then I have to take away 2 from 67 to make 65 so then its 65+30 how much easier is that! your answer is 95.
what is your favorite strategy in math?
