This algebra and functions lesson focuses on writing addition number sentences. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the word problem and identify addition key words and number words. Then, they write an addition number sentence and practice reading aloud. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.

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.

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.

This algebra and functions lesson focuses on solving problems involving rates. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem, identifying the given rate and the given and unknown quantities of the other rate. Then, they set up the proportion and solve it by cross-multiplying.

This algebra and functions lesson focuses on using a variable to write an algebraic expression. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem, identifying the unknown amount, the given number or known amount, and the operation (using clue words or actions such as sum, difference, product, or quotient). Then, they write the algebraic expression. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.

This geometry lesson covers how to solve 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 substitute the given angle measures into the equation and solve it. Finally, they write the solution using the angle measure and degree symbol.

This Algebra 1 lesson teaches students how to solve rate problems. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Students will identify whether the problem is a distance addition or equal distance model. Then, they will organize the information using a distance, rate, and timetable, representing unknown values algebraically. Finally, they will set up an equation using distances, solve for the unknown rate or time, find remaining unknown values, and interpret the solution in a complete sentence. In addition to the lesson, there are two pages of Independent Practice and six pages of periodic review.

This circles lesson teaches students how to identify inscribed and circumscribed angles of a circle and to use the appropriate formula to determine the measure of the angle from the intercepted arcs. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will identify given and unknown information and apply the correct formula to find the unknown angle.
