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 give directions to move an object from one position to another on a grid.
Key Notes
- Up, down, right and left can be used to move objects on a grid.
- Combine direction with a number of squares to give accurate directions.
- The move can include a horizontal and a vertical direction.
Vocabulary To Learn
- Grid: A set of lines used to help us accurately draw graphs is known as grid.
- Position: Position means where something is located (often in relation to something else.)
- Horizontal: Horizontal means side to side, like the horizon.
- Vertical: Vertical means in an up-down direction.
Common Mistakes To Avoid
- Pupils may mix up directions, for example, moving left instead of right, or up instead of down. Pupils might start their movement from an incorrect position, leading to an inaccurate final location.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Up, down, right and left can be used to move objects on a grid. Combine direction with a number of squares to give accurate directions.
2. Use this key word in a maths sentence and explain it clearly. 'Grid'
A set of lines used to help us accurately draw graphs is known as grid. 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 mix up directions, for example, moving left instead of right, or up instead of down. Pupils might start their movement from an incorrect position, leading to an inaccurate final location. Correction: Use clear and consistent language when teaching directions. Reinforce understanding by having students physically point or move in the indicated direction.
