True and False Equations
What does English have to do with math? Teach your class the "grammar" of a number sentence. Sentences with correct grammar can be false! Understanding of a number sentence leads to a comparison with equations.

An Exploration of the Slope of a Line
Learners define the slope of a line. For this algebra lesson, students differentiate between parallel and perpendicular lines using their slopes. They rewrite equations in slope intercept form and explain the meaning of the slope.
Curated OER
Write an Equation of a Line Given Slope and a Point
Ninth graders are investigating slope of a line. The line is plotted using the slope and points on a line. They also write an equation given the right information. The use of a PowerPoint is part of the presentation.
Curated OER
Multiples of a
Sixth graders use problem solving strategies to evaluate linear expressions by substituting values. They substitute values for the letters in their names before applying the concept to other words. They complete worksheets in which they...
Curated OER
Transposition Cryptography
Learners differentiate the types of cryptosystems and use them to communicate privately. In this algebra lesson, students use substitution and transposition to identify the cryptographs. They send and receive cryptograms as they try...
Curated OER
Tilted Squares and Right Triangles
Learners investigate squares. They generate patterns from structured situations and find a rule for the general term and express it using words and symbols. Students generate patterns from a rule and substitute values and formulas.
Curated OER
Doubling Up
Fifth graders explore the powers of two and substitute values into their own names by solving a math word problem. They perform calculations with powers of numbers, find square roots, and explain the relation between a square root and a...
Curated OER
Go Negative
Fourth graders advance to new levels in the lesson we're dealing with here. It is the fourth of a sequence of six dealing with the same theme. These develop from Level 2 to Level 5. In the process they involve number concepts at the...
Curated OER
Write the Equation of a Line Given the Slope and a Point
Students write the equation of a line given the slope and y-intercept. In this algebra lesson, students are given a point a the line and the slope of the line and are asked to write an equation of the line. They relate lines to real life...
