Add It Up

Second grade is working on adding and subtracting with in 1000.  We have been discussing different strategies to solve problems.  More importantly, we have been explaining our mathematical thinking.  I love to hear how they are thinking and solving problems.

In class, we have spent time on three important addition strategies specifically; bracketing, open number line, and the traditional regrouping (carrying) method.  Each of the students made a video to "teach" the strategies.  All the videos are delightful, it was hard to just choose one to share!



The students know the strategies, so now we just need to practice, practice, practice.  For addition we have been playing different games that involve adding double digit and triple digit numbers.

Here is a great game that would be really easy to play at home.  The students love playing it at school.  All you need is a deck of cards and some scratch paper.
