These matrices help students better understand perimeter and area by figuring missing information when given only partial problem informaiton.
Why matrices help students:
Students must think about a problem in different ways.
It helps students makes sense of math.
It connects various models and representations.
It exposes students to the various ways they may be tested on this standard.
These matrices may be done separately or together. They can be printed on regular paper to turn in or made into center mats by printing on white cardstock and laminating.
Given the area or perimeter information, students must solve for the missing information.
3.6C determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row
3.6D decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area
3.7A represent fractions of halves, fourths, and eighths as distances from zero on a number line
