Math Strategies for Addition

                                                              Open House...
Thank you to everyone who attended last nights 'Open House' and participated in our mini Scavenger Hunt. I also loved reading your 'put up' messages to your children. I wish I could post a picture of their little faces as they beamed, sat up a little straighter or  giggled as I read them aloud today. Each time I tried to stop and save a few, they would chant, 'more, more, more'. Now if I could only garner that much enthusiasm for everything :)

Tumblebooks- We had a chance to look at the Burlington Public Library site for more free books to read. There are a number of Robert Munsch books on there that are read by Robert himself. (I'm not on a first name basis with the man but Mr Munsch seemed so formal) You can access it by going to FM library links section or use this link:

                                               Math Strategies for Addition:

                                                       
Here are some of the basic strategies that I am introducing in class...

1) Counting On...put the big number in your head and count up ( 3 +9 = think 9...10, 11,12)

2) Turnarounds...if  2+9= 11 then 9+2 =11 !!

3) Zero Facts....when 0 is added to any number the number stays the same

4) Doubles ...picture 2 groups in your head...5 +5  

5) Doubles plus 1 ....think of the doubles picture and add 1

6) Almost Neighbours...when numbers are 2 apart on the number line, go to the middle number and double
     it...6+8 ___ go to 7 and double it....so 7+7+14, 6+8 must also be 14

Hope this is helpful to you as we move forward in our math units for both grades 1 and 2. I will provide subtraction strategies when we start that a little later in the year.
