This lesson is designed to support student understanding of addition and subtraction in real-world situations. This lesson builds on student understanding in 3rd grade to add and subtract using place value strategies. Students are familiar with decimal place values to the hundredths place due to their work with money. However, the connection should be explicitly made.
The two instructional blocks in this lesson are adding decimals and subtracting decimals
The first instructional block has students adding decimals by using the standard algorithm. Students practice this strategy with real world problems.
The second instructional block has students practice subtracting decimals with real world problems.
Intentional scaffold is built in to support alignment of multi-digit addition and subtraction problems using decimal place value.
