Answer to Question 1 (4 marks)
1. Read along the horizontal axis first, then up the vertical axis (along the corridor, then up the stairs). A is 2 along and 4 up: A (2, 4). B is 5 along and 1 up: B (5, 1). C is 0 along and 3 up: C (0, 3) (3 marks: 1 for each point).
2. A point on the vertical axis has not moved along at all, so its x-coordinate is 0. That point is C (1 mark).
Answer to Question 2 (4 marks)
1. Two corners have y = 2 and two corners must have y = 5; two corners have x = 6 and two must have x = 1. The missing corner is (1, 5) (1 mark).
2. The width is 6 − 1 = 5 units and the height is 5 − 2 = 3 units. Perimeter = 5 + 3 + 5 + 3 = 16 units (2 marks: 1 for the side lengths, 1 for 16).
3. Area = width × height = 5 × 3 = 15 square units (1 mark). Counting the squares inside the rectangle on the grid gives the same answer.
Answer to Question 3 (4 marks)
1. Moving right adds to the x-coordinate and moving up adds to the y-coordinate: (2 + 4, 3 + 2) = (6, 5) (1 mark).
2. Moving left subtracts from x and moving down subtracts from y: (7 − 3, 5 − 1) = (4, 4) (1 mark).
3. Compare the x-coordinates: 1 to 5 is 4 more, so 4 right. Compare the y-coordinates: 6 to 2 is 4 less, so 4 down. The translation is 4 right and 4 down (2 marks: 1 for each direction).
Answer to Question 4 (4 marks)
1. Add 2 to every x-coordinate and 3 to every y-coordinate. P (1, 1) becomes P′ (3, 4), Q (4, 1) becomes Q′ (6, 4) and R (1, 3) becomes R′ (3, 6) (3 marks: 1 for each corner).
2. The base P′Q′ runs from x = 3 to x = 6, so it is 6 − 3 = 3 units. The original base was 4 − 1 = 3 units: a translation slides a shape without changing its size (1 mark).
Answer to Question 5 (4 marks)
1. The gate (0, 0) and the cafe (5, 0) are on the same horizontal line, so the distance is 5 − 0 = 5 squares (1 mark).
2. Cafe (5, 0) to pond (5, 4): same x, so 4 − 0 = 4 squares up. Pond (5, 4) to playground (2, 4): same y, so 5 − 2 = 3 squares left. Whole path: 5 + 4 + 3 = 12 squares (2 marks: 1 for the three parts, 1 for 12).
3. Each square is 20 m: 12 × 20 = 240 m (1 mark).

How to use these Year 4 coordinates and translation test answers

First, sit the test under timed conditions before you read anything here. Then mark each answer and give yourself the marks shown, including method marks. When you lose marks, read the worked solution and find the step you missed. After that, revise the coordinates and translation lesson and redo the worksheet.

Also, the Year 4 coordinates and translation test answers are available as a PDF, so a teacher can mark printed tests quickly. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
