Topic 3: Decimals and Volume
This topic builds on students’ prior knowledge of volume, area, and decimal
operations. Students are introduced to the language of prisms and pyramids so that distinctions can be made as they
solve volume and surface area problems. Through problem-solving activities with volume, students review addition and subtraction of decimal numbers and
continue operating with decimals, with the eventual goal of fl uency. Students decompose three-dimensional solids into two-dimensional nets and compose solids from nets. Students review whole-number and decimal multiplication and learn how to long divide with whole numbers and decimals..
