Subtract Two-Digit Numbers (With Decomposing)
- Grade:
- 2
- Subject:
- Math
This number sense lesson focuses on subtracting numbers (two digits long). The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students determine if regrouping is needed. Then, they subtract digits in the ones place, and in the tens place. Finally, students read the problem and sum aloud. In addition to the lesson, there are "lining up subtraction" flashcards along with seven pages of Independent Practice and review with questions modeled after current adaptive testing items.
Subtract Multi-Digit Numbers With Decomposing
- Grade:
- 3
- Subject:
- Math
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.
Subtract Multi-Digit Numbers (with Decomposing)
- Grade:
- 4
- Subject:
- Math
This number and operations in base ten lesson teaches students how to subtract multi-digit numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will extend their knowledge of multi-digit subtraction by adding numbers up to the hundred thousands. Students will apply the standard addition algorithm with a focus on correctly lining up the numbers by place value and decomposing digits correctly. This lesson also contains real-world examples for students to practice with.
Subtract Whole Numbers (Standard Algorithm)
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on subtracting whole numbers. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the subtraction problem and line up the numbers by their place value. Then, they subtract each column (starting from the right) and regroup, if needed. Finally, students interpret the difference. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
Subtract Decimal Numbers
- Grade:
- 5
- Subject:
- Math
This number sense lesson focuses on subtracting decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students identify the numbers that are being subtracted, if needed. Then, they line up the decimal numbers by place value, making sure the decimal points line up. Finally, they subtract, line up the decimal point in the difference, and interpret the difference. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.
