Lesson objective: Apply understanding of the relationship between the three whole numbers in a multiplication and division equation to solve real world problems.

This lesson provides an opportunity for students to apply their knowledge and understanding of the relationship between multiplication and division to a real-life situation. Students are asked to write and solve multiplication and division equations to find unknown numbers related to the purchase of art supplies and then use equations to distribute the supplies equally among 4 work tables.

Key Concept students will use: 

  • we can use the relationship between the three whole numbers in a multiplication and division equation to identify a missing number that makes the equation true

Skills students will use:

  • write and solve multiplication and division equations with unknowns
  • use division to equally distribute items 
  • answer questions to real world problems involving multiplication and division

Students engage in Mathematical Practice 2 (reason abstractly and quantitatively) as they write equations with unknowns to find unit cost, quantity, or total cost of several art supply items and then write equations to determine how to equally distribute the items to student work tables.

Key vocabulary: 

  • distribute
  • division
  • equation
  • multiplication
  • one-half
  • unknown
