Reveal Math Grade 5, Unit 12: Coordinate Geometry

In this unit, your child learns to use the coordinate grid. They locate and plot points like (6, 3) from the origin, name the x-coordinate and y-coordinate, and graph points from real situations, explaining what each one means. It follows the unit on classifying shapes and closes the fifth-grade year, laying groundwork for graphing in middle school.

Sample questions to try together

These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.

Question 1 of 3

In the coordinate plane, the point (4, 2) is plotted. What does the number 2 in this ordered pair represent?

A coordinate grid, x from 0 to 5 along the bottom and y from 0 to 5 up the side. A point is at (4, 2).
  • The total distance from the origin to the point.
  • The distance up from the x-axis.
  • The distance right from the y-axis.

How you can help

  1. Play hide-and-seek on a hand-drawn grid: hide a 'treasure' at a point and give clues as ordered pairs, going across first and then up.
  2. Time a regular walk every few days, then graph days across and minutes up. Ask your child what one point says in a full sentence.
  3. Look at a park or zoo map with a letter-and-number grid. Ask how it is like a coordinate grid and how it is different.

Where kids can get stuck

  • Counting the origin as 1 instead of 0, so each point lands one step short of where it belongs.
  • Plotting (5, 2) by going up 5 and across 2, putting the point where (2, 5) belongs.
  • Ignoring the scale, treating each grid line as 1 when the axis counts by 5s or 10s.

Practice makes perfect

Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.

Words your child will hear

coordinate grid
A grid with numbered lines across and up, used to locate points.
origin
The point (0, 0), where the two axes meet.
x-axis
The number line that runs across the bottom of a coordinate grid.
y-axis
The number line that runs up the side of a coordinate grid.
x-coordinate
The first number in an ordered pair; how far across to go.
y-coordinate
The second number in an ordered pair; how far up to go.
ordered pair
Two numbers in order, like (6, 3), that name one point on a grid.
scale
How much each step on an axis stands for, like counting by 5s.
