In Classroom Resources, Number and Algebra

The focus of this activity is for students to not just to find solutions for each of the numbers, but to accurately use their knowledge of the order of operations to accurately record each equation.

  • Identify the qualities of a good mathematician
  • Demonstrate the qualities of a good mathematician
  • Explain and record thinking using a systematic approach
  • Identity the different mathematical operations
  • Explain the order of operations
  • Use brackets to modify the order of operations
  • Explain the use of brackets
  • Record and solve equations that involve the use of brackets and different operations


Curriculum Connections: AUSTRALIAN CURRICULUM
  • Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers (ACMNA123)


Curriculum Connections: NSW MATHEMATICS K-10
  • Select and apply efficient mental and written strategies, and appropriate digital technologies, to solve problems involving multiplication and division with whole numbers (ACMNA123)
  • Explore the use of brackets and the order of operations to write number sentences (ACMNA134)


At the end of this lesson students should be able to answer the following questions
  • What do you know about this problem?
  • What is an equation?
  • What does the equal sign mean?
  • What are the different mathematical operators?
  • In what order do you solve operations?
  • What do brackets do in an equation?
  • How can you change the order of operations?
  • What happens if all the same operators are used in the equation?
  • What are other operations we can use?
  • Is there more than one way to find the same solution?
