General Activity Information
 Activity ID: 2706 Title: Balancing Act Digital Tool/Resource: Illuminations Pan Balance-Expressions Web Address – URL: https://www.nctm.org/Classroom-Resources/Illuminations/Interactives/Pan-Balance----Expressions/ Overview: In this activity, students will create equivalent expressions using an online tool. Students are provided two expressions and asked to find the value of the variable to make the two expressions equal. Then, students are provided an expression and a value of the variable and asked to generate a different expression equal to the original expression. Through the online digital tool, students are able to substitute values and develop strategies for creating equivalent expressions. This provides a great opportunity for students to investigate how to solve problems using multiple methods.Balancing Act Student Response Page
Associated Standards and Objectives
Content Standard(s):
 Digital Literacy and Computer Science DLIT (2018) Grade: 7 27) Identify data needed to create a model or simulation of a given event. Examples: When creating a random name generator, the program needs access to a list of possible names. Mathematics MA2019 (2019) Grade: 7 7. Generate expressions in equivalent forms based on context and explain how the quantities are related. Alabama Alternate Achievement Standards AAS Standard: M.AAS.7.7 Match equivalent expressions using the properties of operations. M.AAS.7.7a Identify a pattern in a sequence of whole numbers with a whole number common difference (e.g. when skip counting by 5, the whole number common difference is 5).
Learning Objectives:

Students will use an online tool to create equivalent expressions.

Students will determine the value of a variable to create equivalent expressions.

When given the value of a variable and an expression, the student will generate a different expression equivalent to the original expression.
