Most of us grew up with the belief that there was one way to add and one way to subtract large numbers - regrouping. It may seem silly to some that students are now taught several different ways to solve a problem. In order to help students become fluent mathematicians, we now teach mathematics conceptually. This helps students to build an understanding and make connections. At the beginning of the year, we worked hard to build a firm foundation of number sense .
At this point of the year, students should feel more confident with their conceptual strategies and departing from less efficient ways to solve problems (such as tally marks). If you were unable to attend our Parent Math Night, you can download the math strategy sheet on our Second Grade Parent Wiki. There is a link on the right side of the blog and you can search "math strategies" on the wiki.
Thank you for teaching us stategies! I am now more comfortable with Regrouping and Compensation.
