Unit Summary
In this unit pupils will interpret numbers greater than and less than zero. They will read and write negative numbers, explain how the value of a number relates to its position from zero, positioning on a number line.
Lesson Summary
You will learn to explain how negative numbers are used on a coordinate grid.
Key Notes
- Coordinates can include negative values
- The x or horizontal value is always the first value in a coordinate
- The y or vertical value is always the second value in a coordinate
Vocabulary To Learn
- Coordinates: Coordinates are a set of values that show an exact position.
- Quadrant: Any of the four areas made when a plane is divided by an x and y axis.
- Axis / Axes: The x and y lines that cross at right angles to make a graph or grid.
Common Mistakes To Avoid
- Pupils can get mixed up with which comes first, the x or y axis, when reading/plotting coordinates.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Coordinates can include negative values. The x or horizontal value is always the first value in a coordinate.
2. Use this key word in a maths sentence and explain it clearly. 'Coordinates'
Coordinates are a set of values that show an exact position. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils can get mixed up with which comes first, the x or y axis, when reading/plotting coordinates. Correction: There are lots of aide-mémoires to remember the order. However, regular practice using a stem sentence like the one in the lesson will help.
