Mrs. Fredrickson's 2nd Grade Class

100's Chart
Here is a 100's chart that you can print to use at home for help with math if you'd like.  The method that we use at school is to count up which means if the problem is 6+8, the child should start on the biggest number (8) and count up 6.  During subtraction it's the same technique only they'll "hop" backwards.  We also encourage using the patterns of a 100's chart and the fact that if you go up or down from a number it is + or - 10.  Students may choose to use this shortcut.  For example if the problem is 22 +12, they would begin on 22 and then instead of "hopping" 12 times they would go down one (+10) and then over 2 in order to make 12.

As we move forward in math over the course of this year and do two-digit subtraction and addition these techniques and familiarity of the 100's chart will be helpful.
