Be a rock detective
Hand each table a few rocks and a magnifying glass. Kids describe color, texture and shiny spots, then sort them their own way and explain their rule. Observing real rocks before reading about them gives the vocabulary something to hold on to.
Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.
