Estimate and Measure Stage 2 Recording Sheet

Narrative
Students choose an object and a unit (inches, feet, centimeters) to measure it with. They estimate the length of the object and then measure to see the actual length to the nearest whole unit.
Additional Information
Gather or identify objects of various lengths (pencils, markers, books, glue, scissors, shoes, tape dispensers, sides of desk, length of bulletin board).
