Lesson objective: Apply understanding of addition and subtraction and knowledge of using a variety of tools to solve problems and to create equations.     

This lesson provides an opportunity for students to apply their understanding of the meaning of addition and subtraction to a real-life situation. Students are asked to examine pictorial solutions to addition and subtraction problems to create their own equations. The pictorial solutions will be done on a variety of familiar tools such as number lines, ten frames, snap cubes, or number bonds.

Key Concept students will use: 

  • The meaning of addition and subtractions do not change, no matter which tool you are using.

Skills students will use:

  • Addition can be thought of as "putting together" and subtraction as "taking apart."
  • Addition and subtraction problems can be solved using a variety of tools.
  • Equations can be used to represent mathematical problems.

Students engage in Mathematical Practice #3 (Construct viable arguments and critique the reasoning of others) as they share equations they have created and discuss their reasoning for which equatioon is the best match to a pictorial solution. 

Key vocabulary: 

  • tool 
  • addition
  • subtraction
  • equation
