Add Up To Four Two-Digit Numbers
- Grade:
- 2
- Subject:
- Math
This Common Core numbers and operations in base ten lesson covers how to add multiple two-digit numbers. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students are asked to add the digits by place value. Students are also asked to regroup any group of ten or more with concept demonstrations to show what regrouping means in real terms. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
Add Three-Digit Numbers (With Regrouping)
- Grade:
- 2
- Subject:
- Math
This number sense lesson focuses on adding numbers (three digits). The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students add the digits in the one's place and regroup if the sum is ten or more. Then, they add the digits in the tens place and regroup if the sum is 10 or more. Finally, students read the addition problem and the sum aloud. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
Add Multi-Digit Numbers (with Composing)
- Grade:
- 3
- Subject:
- Math
This lesson covers how to add numbers with composing. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will line up the numbers by the place value of their digits, add the digits in each place value, compose the number (if needed), and then interpret the sum. In addition to the lesson, there are four pages of Independent Practice with questions modeled after assessment items.
Multiply a Multi-Digit Number By a One-Digit Number (with Composing)
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on multiplying numbers with regrouping. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students multiply the bottom number with each digit of the top number, regrouping if needed (add the regrouped number, if needed). Then, they read the product aloud. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
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.
Multiply Decimal Numbers
- Grade:
- 5
- Subject:
- Math
This number sense lesson focuses on multiplying decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students multiply the bottom factor with each digit of the top factor, regrouping if needed. Then, they count the total number of decimal places in the two factors and place a decimal in the product that many places to the left. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
