In math we worked on story problems. We worked with problems where the sum was known, but the addends were not. For example, "Miss Wolfe has seven jellybeans. Some are red, and some are green. How many of each color could she have?" For this, children are using what they know about decomposing to find possible answers. 7= 1 + 6, 7 = 2 + 5, etc.
Have a nice evening!
