Describing Movements

Mathematics · Geometry · procedural

Describe movements between positions as translations of a given unit to the left/right and up/down

Sign in to track this

What mastery looks like

  • Describe moving from (2,3) to (5,3) as 3 units to the right
  • Translate a shape 4 units right and 2 units up and state the new coordinates
  • Predict where a point will be after a given translation

Check your understanding

If a shape is at position (2, 3) on a grid and you tell Describing Movements to move it four squares right and two squares up, can they work out its new position without drawing it first?
