Coordinate Plane
Read, plot and reason about points on a coordinate grid.
Every point on a graph has an address, and Coordinate Plane teaches how to read and write it on a grid children can tap. Early rounds ask them to read the coordinates of a lettered point or find the point that matches a pair. Later the grid grows to include negative numbers, and the child plots a point by tapping an intersection and pressing a button to check it.
The game moves from the first quadrant to all four, then on to the signs of coordinates, distance, reflections and finding the fourth corner of a rectangle. Every answer is explained in terms of how far across and how far up or down, which keeps the focus on what the numbers mean.
What children practice
- Read the ordered pair for a labeled point on a grid
- Plot a point by going across for x, then up or down for y
- Name the quadrant of a point from the signs of x and y
- Recognize points that sit on the x axis or the y axis
- Find the distance between two points on a grid
- Reflect a point across an axis and find a rectangle's fourth corner
Levels
- Level 1: Read a point
- Level 2: Plot and find points
- Level 3: All four quadrants
- Level 4: Signs and axes
- Level 5: Distance
- Level 6: Reflect and rectangles
How it works
- Six levels go from first quadrant points to reflections and rectangles.
- Some questions are multiple choice, and others ask the child to tap a grid intersection and press Check my point.
- A wrong answer says try again, and a right one comes with a note about how far across and how far up the point is.
- The speaker button next to each question reads it aloud.
Best for: A good fit for grades 4 to 7 when a child is learning to graph points or starting to work with negative numbers.
Tip for parents: Play a paper version: draw a grid, hide a small treasure at one point and give clues like three across and two up. Always say the x number first, then the y number.
Questions parents ask
Does it include negative coordinates?
Yes, Level 3 opens the grid to all four quadrants with numbers from negative 5 to 5. Level 4 looks at signs and points on the axes, and some of its grids reach 10 in each direction.
How does a child plot a point?
The prompt names a pair such as (3, 4). The child taps the matching intersection, can tap again to move the dot, then presses Check my point. If the spot is wrong, they can move it and check again.
What are the reflection questions like?
Level 6 shows point P and asks for its new coordinates after a reflection across the x axis or the y axis. The explanation says which coordinate changes sign, so children can see the pattern for next time.
