Click here for the Partitioning Lessons!

Suggested Dates:

December 16- December 19

As an additional resource for the 1^{st} grade partitioning lessons, teachers can use the 4 lessons included in Investigations and the Common Core book (pg. CC37-CC57).

Keep in mind that the goal is for students to notice that when we create more shares, the size of the share gets smaller.

The lessons should be adjusted by providing cut-outs of squares, rectangles and circles for students to fold and cut.

Discussions should occur as to what happens when they increase the number of cuts or folds. The reference to partitioning as it relates to time should be omitted from these lessons.
