Coordinates in four quadrants: what children learn
In this game children read coordinates with negative numbers and move points across the axes. The rules are the same as in the first quadrant: along first, then up. Negative numbers mean left of or below the origin.
Supports part of Common Core 6.NS.C.8: points in all four quadrants of the coordinate plane. This focused game does not cover the entire standard.
Common Core connection: 6.NS.C.8. This is focused practice for part of the standard.
How to play
Answer 10 questions before the clock runs out. Tap an answer, or press 1 to 4. Each game has 10 multiple-choice questions and a 150-second timer. A wrong answer shows the correct one before moving on. You earn up to three stars depending on your score.
Step by step
- Find the origin. The origin is (0, 0), where the axes cross.
- Negative x means left. A point with a negative first number is left of the y-axis.
- Negative y means down. A point with a negative second number is below the x-axis.
- Moving across zero. Moving 5 right from −2 is −2 + 5 = 3. Count on through zero.
Worked examples
Example 1: A point is 4 squares left of the origin and 2 squares up.
Working: Left means negative x.
Answer: (−4, 2)
Example 2: A point starts at (−2, 3). It moves 5 right. Where is it now?
Working: −2 + 5 = 3.
Answer: (3, 3)
Example 3: A point starts at (4, −1). It moves 6 left. Where is it now?
Working: 4 − 6 = −2.
Answer: (−2, −1)
Common mistakes and how to fix them
- Losing the negative sign. Say 'negative' aloud every time you read a coordinate.
- Counting across zero wrongly, so −2 + 5 = 7. Use a number line and count on through 0.
- Writing coordinates the wrong way round. Along the corridor, then up or down the stairs.
Activities to try at home
- Play battleships on a grid with four quadrants.
- Draw a map with the house at the origin and name places with negative coordinates.
- Talk about temperatures below zero as a link to negative numbers.
Ideas for the classroom
- Students plot a shape in one quadrant and translate it into another.
- Use the hall floor as a big four-quadrant grid.
- Give coordinate clues that cross the axes for a treasure hunt.
