March 5

Today was a long hard day of mathematics. Specifically, subtraction with borrowing.

Let's say this is a ten: ---------- and this is a one: -

 3 6       ----------     - - - - - -  Now subtract 9! Kids can't so they need to use a ten to make 10 ones.
-   9       ----------                    They actually cross out the ten and draw in 10 ones. Next, they subtract
             ----------                     9 ones by crossing them out. They count how many ones are left and
                                               write that in the ones column. They count the tens left and write that                                                      in the tens column.

Looks like this:

For homework, have them try these:

A)   2 8
     -    5





B)   4 2
     -    6


I have booked the pool from 10-12 on March 22 for all of the grade 2s. We will be bussing there and need a 1:4 supervisor to student ratio in the pool. I need 4 parents to help on the day. Let me know. I will send permission forms when I find time to do it.

We are going to Covenant Christion School to watch a play put on by their junior high. That is in the afternoon of Thursday, March 21. I will send permission form later.
