Group it by tens
Give kids a big pile of beans or cubes and ask them to count by making groups of ten. Then group ten tens into a hundred. Grouping a huge pile shows kids why counting by tens and hundreds is so much faster than counting by ones.
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.
