This is a set of Task Cards suitable for 4th, 5th, 6th Grade Math. Students measure the area and perimeter of quadrilaterals.
I printed and laminated off several sets to be used as a Math center in my room. That is one option.
You could print off enough sets for every student, pairs of students, or even small groups of students.
You could also use as an assessment tool.
Common Core Aligned for 4th Grade.
Included is a recording sheet and an answer key!
