Math Homework: Jan. 8th to 12th

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.
