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 write coordinates for already marked points in the first quadrant of a coordinate grid.
Key Notes
- Count along the x-axis and then the y-axis to find the coordinates for the marked point.
- Coordinates are recorded with the horizontal distance along the x-axis, then the vertical distance along the y-axis.
- Coordinates are recorded in brackets with the numbers separated by a comma.
Vocabulary To Learn
- x-axis: The x-axis runs horizontally (left-right) through zero.
- y-axis: The y-axis runs vertically (up-down) through zero.
- Origin: The origin is where the x-axis and y-axis cross. It has the coordinate pair (0,0).
Common Mistakes To Avoid
- Pupils might confuse the x-axis and y-axis, leading them to count along the wrong axis.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Count along the x-axis and then the y-axis to find the coordinates for the marked point. Coordinates are recorded with the horizontal distance along the x-axis, then the vertical distance along the y-axis.
2. Use this key word in a maths sentence and explain it clearly. 'x-axis'
The x-axis runs horizontally (left-right) through zero. 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 confuse the x-axis and y-axis, leading them to count along the wrong axis. Correction: Reiterate that the x-axis runs horizontally (left to right) and the y-axis runs vertically (up and down). Use visual aids, like arrows or labels, to clearly mark the axes on the grid.
