Coordinates (age 8+)
Plot specified points on a coordinate grid and draw sides to complete a given polygon
Lesson
Set out your lesson
Plot ordered pairs and use side relationships to complete a polygon.
Before teaching
Use this short check, then start teaching.
Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Walking the Block
Before you open · source notes
Walking the block supports using coordinates on a plane. Not every transformation proof.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk the learner to name coordinates for a path around a block.
Opening this link does not save learning or assess mastery.
Source, access and review notes
Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Plot points (1,1), (1,4), (5,4), (5,1) and join to make a rectangle
- Given three vertices of a square, plot the fourth vertex
- Complete a triangle by plotting the third vertex at given coordinates and drawing sides
“If your child is given three coordinate pairs on a grid, can they plot each point and then connect the dots to draw the correct triangle or rectangle?”
