Touch math aas no in the 70s. It was the mid 80s. I learned regular math. My younger sister learned touch math. I was born in the early 70s. She was born in the late 70s and went to elementary in the early 80s, around 82 for second grade. |
I'm gonna guess you are not in STEM. Born in '70, never heard of dot math. That sounds slow. To other PP that stated 6 + 7 = 13 is memorization, at some point, it does become memorization, but in the beginning, it is not. The way I taught my kids is by using a system like an abacus (take away, add more), with fingers when they were in preK/k. I taught my DC years back, aged 9 now, that the way I do it is by going up to the nearest 0... and then add the remaining number: 6 + 7 -- > nearest 0 to 7 is 10... so to get to 10 from 7 is 3 6 -3 = 3 --- > 10 + 3 = 13 Most 1st/2nd graders can do the two steps in their heads. This method can work for 10's additions, too. Once you go beyond 10's I have to break it down furhter, or do it on paper. Single digit addition less than 10 just becomes visual I think, then eventually memorization. |
