Polygons/Measurement:
In order to be effective, pieces should
be used daily. Have students to record
responses on blank monthly calendar
or in a journal.
For days 12, 15, and 16, provide the
additional pages for students because
the actual day card is small and may be
difficult to see unless up close.
COS Objectives:
CS 3: Solve word problems that
involve decimals, fractions, or money.
