# SAVY 2019: Session 5, Day 5 – Solving for the Unknown (Rising 3rd/4th)

Posted by on Friday, July 19, 2019 in Grade 3, Grade 4, SAVY.

Hello SAVY parents!  Today was a very exciting day as we spent most of our day getting prepared for your arrival at Open House.

Our culminating activity, “At the Mall” was a project where students were able to setup the classroom as if they were at the mall with a variety of shops.  Pairs of students worked together as the owners of each shop, and were charged with the task of making signs advertising their store’s merchandise in the form of equations.  There were two types of signs on display.  One sign used single equations, and one used a set of equations to advertise special deals. Students used symbols that stand for the variables in the equations.  Store owners had to write and solve equations that would represent the cost of the items in their store.  They also were charged with the responsibility of developing a poster that would advertise a store sale that used a set of equations.

The store simulation was an opportunity for students to demonstrate that they understand that expressions on both sides of the equal sign must have the same value.  It also represents that students are able to use the substitution method to make sure the value for each variable is correct.  Students may not have realized that they have been working with equality the entire unit. In this culminating lesson, students synthesize their understanding of solving equations.  As students wrote and solved sets of equations, they exhibited their understanding of the big ideas of variables and equality.

Thank you for your participation in our Open House activity. It is my hope that your child obtained a wealth of knowledge while here with us at SAVY. We appreciate your participation in this program and hope you will return for other courses.  It has been a pleasure for me to be able to ignite a flame in the developing minds of all the students that were with me this week!

Thank you so much!!
