### Subtract Multi-Digit Numbers With Decomposing

This lesson covers how to subtract numbers with decomposing. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will line up the numbers by place value of their digits, subtract the digits in each place value, decompose the number (if needed), and then interpret the difference. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the assessment items.

### Add Money Amounts

This number sense lesson focuses on adding money amounts. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the problem and set up the addition by lining up the decimals. Then, they find the sum of the money amounts by adding digits in each column (starting from the right) and writing in the decimal point and the dollar sign. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
