Grade 4 Unit of Study 9: Equalities

In This Unit of Study…

Students will explore equalities and determine if equations are true or false. Students will explain how they determined an equation was true or false using comparative relational thinking. When given a real-world or mathematical context, students will write an equation involving multiplication or division using a variable for the unknown. Students will also solve for the unknown.
