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 solve problems involving marking and translating points in the first quadrant on a coordinate grid.
Key Notes
- Coordinates are recorded in brackets with the numbers separated by a comma.
- Count along the x-axis and then the y-axis to find the coordinates for the marked point.
- The shape made with the new points after translation should be exactly the same shape and size as the original shape.
Vocabulary To Learn
- Translate / translation: Sliding or moving a shape without rotating or flipping it means to translate.
Common Mistakes To Avoid
- Pupils might write the y-coordinate (vertical distance) first instead of the x-coordinate (horizontal distance).
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Coordinates are recorded in brackets with the numbers separated by a comma. Count along the x-axis and then the y-axis to find the coordinates for the marked point.
2. Use this key word in a maths sentence and explain it clearly. 'Translate / translation'
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 write the y-coordinate (vertical distance) first instead of the x-coordinate (horizontal distance). Correction: Reinforce the correct order by teaching "x comes before y" just like in the alphabet. Practice with examples and devices like "along the x-axis, then up the y-axis" to solidify this concept.
