Expand the the comparative language of young mathematicians with a hand-on weight measurement activity. Working independently or in pairs, children compare the weight of large wooden blocks to various other classroom objects, recording their results by drawing the items in either the heavier or lighter side of a two-column table. Though not mentioned in the lesson plan, consider allowing the use of balance scales for making comparisons to avoid any possible confusion with objects having similar weights. Conclude the lesson with a whole-group discussion, allowing children to practice using comparative language as they share their results with the class.
