[quote=Anonymous][quote=Anonymous] Those are very good standards. Using place value to add 76 and 52, for example, means you don't use the "counting on" strategy. You don't say the number 76, and then count on 52 times. You use place value. You add 6 ones and 2 ones, and get 8 ones. You add 7 10s and 5 tens, and get 12 tens, or 120. You add 120 and 8 to get 128. Are you saying you think place value is a BAD way to add??? [/quote] Or you say that 76 + 52 = 78 + 50. Which is a lot easier for me, when I'm doing mental math. And it uses one of those first-grade strategies that the "math expert" calls 'training wheels".[/quote]
