Solve Addition Equations
- Grade:
- 1
- Subject:
- Math
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.
Solve Two-Step Word Problems with an Unknown (4 Operations)
- Grade:
- 3
- Subject:
- Math
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Use a Property of Triangles to Solve for Unknown Angles

Use a Variable to Write an Algebraic Expression
- Grade:
- 6
- Subject:
- Math
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.
Solve Problems Involving Rates

Solve Rate Problems
- Grade:
- High School
- Subject:
- Math
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.
