Dear Parents,
Please find
attached a subtraction grid that shows you all the facts that your child knows
so far this year. Subtraction can be a difficult concept for kids to
understand. We have played some subtraction games and explored different strategies
to help your child learn their basic subtraction facts.
We are now moving
on to learn addition facts. We have been playing some online fact games,
learning some new strategies but mostly I am hoping that the children will
anchor their new learning onto the subtraction facts they already know.
We are starting
with reviewing double facts. Below is a list of doubles that your child should
know:
2+2 10+10 50+50
3+3 11+11 60+60
4+4 12+12 70+70
5+5 15+15 80+80
6+6 20+20 90+90
7+7 25+25 100+100
8+8 30+30
9+9 40+40
We will then move
on to the Commutative Property. Another name that you may know if “Fact
Families.”
Here is an example
using the number 5,7 and 12.
5+7=12 12-7=5
7+5=12 12-5=7
This is a very
powerful strategy. It links subtraction and addition together and it uses a
flip of numbers to get the same answer.
I encourage
families to play cards, math games or visit math websites to support your
child’s learning.
Thank you,
Ms. L. Romeo J
