Find a benchmark
Give each unit a body or object benchmark: a centimeter is about the width of a fingertip, a meter is about a big step, a gram is about a paper clip. Kids use their benchmarks to estimate before they measure.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.
