Estimate 'N Measure
measurement · estimating and measuring perimeter of irregular shapes
Estimate and measure the perimeter of irregular shapes [5.SS(M).3].
Estimate 'N Measure is a measurement game for Grades 3 and 6–8 that focuses on estimating and measuring perimeter. On each turn, students estimate a section of an irregular shape in centimeters, mark the predicted distance, and then measure the actual distance with string. Moving forward depends on how close the estimate is, so precision matters throughout the trip around the shape.
Use it for partner work when you want estimation connected directly to actual measurement instead of treated as a separate warm-up. Students can discuss how their estimates change as they become more familiar with centimeters and the shape. Create a free account to generate lesson support for Estimate 'N Measure.
