He was doinghis Online Aleks math. He had a problem he didn't quite understand (even though we have done them before plenty of times in the winter this school year)the problems were a feaction times a whole number.....
6 X 42 = _____
Connnor said. "That's easy Ki. Just divide 42 by 6 them times it by 2"... all those numbers being spoken confused him. Connor hadhim do it on a calculator....42 divby 6 time 2.. which gave him the correct answer.
then he did another on his own and got it the second try. I think it was 3/4 X 12.
So I got out the beans, empy egg carton, pen and paper. I wrote a 36 at the top of the paper and numbered the sections in the egg carton (1-12). I told him to count out 36 beans (into the lid).then I told him we were going to seperate the beans into groups. I wanted him to seperate the beans into 6 groups (egg carton sections). He did.
6 beans in each.
So I wrote the fractions 6/6. I asked him how many of the 36 beans do we have if we count all 6 of the 6 groups? he said 36. so we wrote 6/6 x 36=36 and said 6 of the 6 groups of 36 beans equals 36 beans (we taught early on that the times symbol is like saying OF- it helps that way). I reminded him that the bottom number of the fraction is the number of groups we are using.
So then I wrote the fraction 1/6 X 36. (remember the 'X' is 'of') so I said "1 of the 6 groups of 36 beans = how many beans?"
He knew. 6.
so I wrote the fraction 3/6 X 36= and asked him how many beans in 3 of the 6 groups of 36.he got it. Then I had him redistribute the 36 beans into 9 groups. and we did the same thing with the fraction 2/3 ( 2/3 X 36 =?)Then he used 24 beans. and I wrote a couple problems for him for his 24 beans.
2/6 X 24= ___
1/8 X 24=___
2/3 X2 4=___
he used the beans and put them into the correct number of groups and figured out each of them. He said he knows how to do but doesn't think he can explain it. Tonight I will have him 'teach' it to his dad.
The sad thing is I have done this same activity with him previously. Ki seems to lose information that isn't used weekly. I can't have him review all his school every week. The memory issue seems to be part of Sensory Integration Disorder (I didn't know my times table by memory till high school and even then still had to count out a lot in my head for multiplication). I read somewhere that a 'normal child' may need to repeat/review something 10 times but a child with SID can take over 50 times of review before they remember it... something like that. I wish I could find the website that has that information
