Unit Summary
In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations.
Lesson Summary
You will learn to move objects including polygons on a grid according to directions and mark the new position.
Key Notes
- Objects covering more than one position on a grid can be moved by giving directions.
- A shape can be moved to a new position on a grid according to the directions.
- If a shape has moved, you can describe the move using left, right, up, down and the number of squares moved.
Vocabulary To Learn
- Polygon: A polygon is a 2D shape made up of three or more straight lines.
Common Mistakes To Avoid
- Pupils may miscount the squares when moving the shape, leading to inaccurate placement.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Objects covering more than one position on a grid can be moved by giving directions. A shape can be moved to a new position on a grid according to the directions.
2. Use this key word in a maths sentence and explain it clearly. 'Polygon'
A polygon is a 2D shape made up of three or more straight lines. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may miscount the squares when moving the shape, leading to inaccurate placement. Correction: Encourage students to carefully count squares from the current position of each vertex and ensure consistency in their counting across the entire shape. Practice counting out loud as a class or in pairs. Relate it to counting on using a number line.
