Happy New 2018 Year!
Math: please take the time to sit with your child and do about 15-20 minutes two or three evenings this week. Other option is to have them do it on their own and then show you the work.
We've been doing "Number Talks" in class two to three times a week since early december. Looking at different strategies to solving computation problems helps students develop basic skills required for all Math and progressing towards more complex problems.
Ask your child to show you at least two different strategies to solve this:
43 - 9
Most will do it the traditional way, lining up the numbers and carrying:
43
- 9
This strategy doesn't necessarily help the child understand.
Another strategy can be 43 - 10 (added 1 to make it friendlier) = 33 (add 1) = 34
Or, use a number line: _____________ 34_+9___43_________________
10 20 30 40 50
Or, use the decreasing number line: ____ 43 -9_34_______________________
50 40 30 20
Or, try 39 - 9 = 30 then add the 4 you took out = 34
Allow your child to think of the different strategies and ones they remember from class. Now, try these with them:
61 - 8 71 - 39 84 - 59 247 - 98
Challenge them to more tricky ones! Have fun! M.K.
