Today we learned two new ways to add. The students were able to quickly grasp partial-sums, but struggled with column addition. I think this is becuase it just seems like the traditional way they add, but with more (and confusing steps). Part of the theory behind our Everyday Math program is to develop a great "number sense." This means learning more than just one way to solve a problem.
I asked students who were struggling to bring home their Student Reference Books (pgs 10&11). These pages can also be access on
www.everydaymathonline.com.
Here are two examples with videos (click the titles) of each method:
More examples can be found
here under "Algorithms," "4," and then "Addition."
