Things go into the two "pans", and the heavier pan will go down, like in a seesaw. If the two things weigh the same, the balance stays balanced. a. The square weighs _____ b. The square weighs _____ c. Solve simple linear equations using a balance beam representation.
students use a modified pan balance to investigate the equivalence of two numeric expressions.

Balance Scales Unit 6: Algebra Grade Level 4 Overview In this activity, students find an unknown quantity, explore the relationship between quantities, and enhance their understanding of the equal sign as equivalence and a balance point. Key Standards M4A1. Students will represent and interpret mathematical relationships in quantitative expressions. b. Represent unknowns using symbols, such. Pan Balance. This is an interactive website where students explore equivalence. Students fill in numbers or expressions on either side of the scale to see if they balance the scale and also can see graphically how the expressions compare. This could be used to introduce the idea of equivalent expressions as an individual exploration activity or a class activity. Students could also use this.
