This week we will have our chapter 6 test in math, which focuses on 3-digit addition and subtraction with and without regrouping (“borrowing”)! Here is a fun video we watched today that gives us a nice trick to remember that “if the number on top is SMALLER than below, it’s time to go with the regrouping flow” when we are subtracting.
Upon returning from our fall break, we began chapter 5 in Go Math! This chapter focuses on subtraction with regrouping. I was excited to introduce this educational song, with helpful rhymes in it, to our class yesterday!
At this time in our second grade classroom, we are focusing on the following addition strategies:
Solving word problems by finding the given information, determining what the problem is asking us to find, and identifying key words or phrases
Solving addition problems with up to 4 addends vertically
While there are number of strategies my students know how to use, I’m a big fan of the “spiral review”, which includes going back and reminding ourselves of some addition tips and tricks we may have picked up in first grade. I recently discovered fun educational hip hop videos created by Flocabulary, a Brooklyn-based company that creates educational hip hop songs and videos for students in grades K through 12. Below is a video that we watched on Monday to remind us of our “tens partners” which will help us add (and subtract… which we will be delving into when we return from the winter break in January) more quickly!
