Title: Equations and Solutions
This lesson will use the substitution property to determine solutions to equations and inequalities. The students will be given a replacement set of values. The student will check the values to determine if the result is true or false. The values that are true will be the solution. The student will graph the inequality solutions on the number line.
This lesson results from the ALEX Resource Gap Project.
Standard(s): [MA2015] (6) 16: Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. [6-EE5]
Title: Balancing Shapes
In this lesson, one of a multi-part unit from Illuminations, students balance shapes using an interactive pan balance applet to study equality, essential to understanding algebra. Equivalent relationships are recognized when the pans balance, demonstrating the properties of equality.
Standard(s): [MA2015] (7) 10: Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. [7-EE4]
Title: ALGEBURST BEJEWELED
ALGEBURST iPad App Web Address URL:
[MA2015] (7) 5: Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. [7-NS2]Digital Tool Description: ALGEBURST Lite is a free game that improves mental math skills. It helps to simplify numeric and algebraic expressions. Play against the clock or at one's own pace to match tiles, explode bombs, and use Starburst and hypercubes to achieve a 3-star rating. Take on periodic challenges to improve accuracy and overall rating.
Title: Pan Balance -- Numbers
This student interactive, from Illuminations, can be used to find numerical expressions that are equivalent to one another. If equivalent expressions are placed in the blue and red pans on the virtual scale, it will balance.
Standard(s): [MA2015] (8) 9: Solve linear equations in one variable. [8-EE7]
