![]() Students should name their representations in different forms (e.g., word, expanded) during classroom discussion.For example, students may prefer to multiply 1.2 × 4 as 12 tenths × 4 to use more familiar numbers ( MTR.2.1, MTR.5.1). Representing multi-digit numbers with decimals flexibly can help students reason through multiplication and division as well.Thinking about 2.1 as 210 hundredths may help subtracting 2.1 – 0.04 easier for students because they can think about the expression as 210 hundredths minus 4 hundredths, or 206 hundredths. This representation shows that 2.1 can also be composed as 21 tenths or 210 hundredths. For example, the image below shows 2.1.Using base ten models flexibly helps students think about how numbers can be composed and decomposed in different ways. During instruction, teachers should emphasize that the value of a base ten block (or another concrete model) is flexible (e.g., one flat could be 1 ten, one, tenth, hundredth, and so forth). Instruction may include multiple representations using base ten models ( MTR.2.1).Composing and decomposing numbers also helps build the foundation for further work with the distributive property in grade 6 ( MA.6.NSO.3.2). Flexible representations of multi- digit numbers with decimals also reinforces the understanding of how the value of digits change if they move one or more places left or right ( MA.5.NSO.1.1). While students have composed and decomposed whole numbers in grade 3 ( MA.3.NSO.1.2) and fractions in grade 4 ( MA.4.FR.2.1), naming multi-digit decimals in flexible ways in grade 5 helps students with decimal comparisons and operations (addition, subtraction, multiplication and division). ![]() The purpose of this benchmark is for students to use place value relationships to compose and decompose multi-digit numbers with decimals.
