Use a Property of Triangles to Solve for Unknown Angles
- Grade:
- 4
- Subject:
- Math
This measurement and geometry lesson focuses on using a property of triangles 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 180 degrees. Finally, they interpret the measurement of the angle. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
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.
Properties of Operations in Simplified Expressions
- Grade:
- 6
- Subject:
- Math
This algebra and functions lesson focuses on identifying the commutative and associative properties in simplified expressions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the expressions as they are simplified. Then, they identify which property of addition was used to simplify them. They justify their answer by explaining that if the addends were put into different places in the expression, then it was commutative, while if the addends were grouped to add them together, it was associative. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.
Solve for Unknown Angles (Supplementary, Complementary, Triangle Interior Angle Sum)
- Grade:
- 7
- Subject:
- Math
This measurement and geometry lesson focuses on solving for unknown angle measures using properties of angles. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students determine the property of angles needed. Then, they solve for the unknown angle measurement using the properties by substituting the given angle measure(s) into the equation and calculating. Finally, they write the solution using the angle measure and degree symbols. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.

Use Real Number Properties to Perform Computational Procedures
- Grade:
- High School
- Subject:
- Math
This Algebra 1 lesson teaches students how to use the properties of real numbers to perform computational procedures. The lesson includes research-based strategies and strategic questions that prepare students for assessments.
