Connecting Representations

Mathematics · Mathematical Thinking · meta

Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)

Sign in to track this

What mastery looks like

  • Write a number sentence (e.g. 14 + 5 = 19) to match a word problem and explain the connection
  • Draw a bar model or part-whole diagram to represent a problem, then solve using the diagram
  • Translate between a concrete model and a symbolic equation, describing what each number represents

Check your understanding

When Connecting Representations solves a word problem, can they draw a diagram or write a number sentence to show their thinking — and then explain how the picture and the numbers match the real situation?
