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 draw polygons on a grid according to a given translation.
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
- Translate / translating: Sliding or moving a shape without rotating or flipping it means to translate.
- Translation: Translation is a transformation in which every point of a shape moves the same distance in the same direction.
- Horizontal: Horizontal is side to side, like the horizon.
- Vertical: Vertical is an up-down direction or position.
Common Mistakes To Avoid
- Pupils might think that translating a shape changes its size, shape, or orientation, rather than just its position.
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. 'Translate / translating'
Sliding or moving a shape without rotating or flipping it means to translate. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils might think that translating a shape changes its size, shape, or orientation, rather than just its position. Correction: Clarify that translation only changes the position of the shape on the grid; the shape itself remains identical in size, shape, and orientation. Use visual examples to compare the shape before and after translation to reinforce this concept.
