Use Repeated Addition to Multiply
- Grade:
- 2
- Subject:
- Math
This number sense lesson focuses on using repeated addition to multiply. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the multiplication problem and find the number that is added, and the number of times the number is added. Then, they fill in the repeated addition chart, add the numbers, and read the multiplication problem. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.
Add Money Amounts
- Grade:
- 3
- Subject:
- Math
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.
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.
Add Multi-Digit Numbers (with Composing)
- Grade:
- 4
- Subject:
- Math
This number and operations in base ten lesson teaches students how to add 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 addition 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 composing tens correctly. This lesson also contains real-world examples for students to practice with.
Use a Property of Quadrilaterals to Solve for Unknown Angles
- Grade:
- 4
- Subject:
- Math
This measurement and geometry lesson focuses on using a property of quadrilaterals to solve for unknown angles. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students list the given angle measurements, then solve for the unknown angle by adding the given angle measurements and subtracting the sum from 360 degrees. Finally, they interpret the measurement of the angle. In addition to the lesson, there are five pages of Independent Practice and review with questions modeled after current adaptive testing items.
Add Mixed Numbers With Like Denominators
- Grade:
- 4
- Subject:
- Math
This Common Core number and operations -- fractions lesson focuses on adding mixed numbers with like denominators. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students will read the problem aloud, identify the whole numbers and fractions, and write them as an addition problem. Then, they will combine the sum of both problems to determine the answer. Finally, they will reduce the fraction or regroup, if needed. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after the Common Core assessment items.
Use Pictures to Add Fractions
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on using pictures to add fractions. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students represent the sum of the fractions by shading the number of equal parts. Then, they add fractions by using the pictures (keeping the common denominator and finding the numerator by adding the number of equal parts). In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
