Unit 5 - Decimals

Content Emphasis/ Big Ideas

In the unit, students begin developing an understanding of decimal numbers. Students use models to compare and order decimals and find decimal and fraction equivalents. Students apply their understanding of whole number addition and subtraction to adding and subtracting decimal numbers. They continue to use estimation and properties of operations to improve their computational efficiency. Students apply all these skills to solve various types of multistep practical problems involving addition and subtraction.
