## About this unit

First, we will measure length using unit squares and rulers, compare and estimate length, and solve length word problems. Next, we will read and make picture graphs, bar graphs, and line plots. From there, we will tell time on analog clocks and count U.S. coins and dollars. After that, we will identify quadrilaterals, pentagons, hexagons, and octagons. Finally, we will break shapes into equal parts.
