Complete every measurement decision, then check your thinking.

This pilot aligns only to uncovered Year 3 records MAT-0077–MAT-0082. MAT-0076 remains attributed to MAT-TOOL-003. It samples perimeter, money/change, clocks, time vocabulary, calendar facts and duration; it does not complete the unit, replace practical experiences, provide a lesson sequence or satisfy an assessment.
