Using objects to model real problems

Use objects, drawings, or simple number sentences to represent a real-world situation (early mathematical modelling)

Lesson

Set out your lesson

Represent a simple counting story with objects and a number sentence.

Before teaching

Activity

Ask for an example of one prerequisite idea; revisit if needed. Historical graph coverage does not establish this learner’s readiness.

Printer, credit, and teaching notes
Instructions

Use drawn objects or safe counters. Read the story without adding extra quantities.

No Printer

Use supplied stage sheets on screen or scrap paper; keep adult keys separate.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.

Check understanding

  • Draw a picture or use objects to represent a simple real-world situation involving counting or comparing
  • Write or dictate a number sentence to describe a real-world situation (e.g. 'I had 5 apples and ate 2')
  • Use the model to answer a question about the situation
“If you describe a simple real-life situation to your child — like "there are 3 birds on a fence and 2 more land" — can they write a number sentence like 3 + 2 = 5 to represent it?”
