This document provides a math lesson for kindergarten students on place value and writing numbers from 1 to 30. It reviews the concept that each number has a place (tens and ones) and name. It uses cubes to demonstrate how to write the number 25 by putting 5 cubes in the ones place and grouping leftover cubes into tens places until all cubes are accounted for. Students are then asked to write other numbers using this method.
