Battle Ship Using Grid Paper
Before you open · source notes
Ships are located with first-quadrant coordinates on grid paper. Use it for plotting points, not every transformation.
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 the coordinates of one ship square and plot a given ordered pair.

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
- Read the coordinates of a point on a grid as (3, 5)
- Explain that the first number is the horizontal distance and the second is the vertical distance
- Identify the coordinates of all vertices of a shape plotted on a grid
“If your child is playing a grid-based treasure map game, can they correctly say where the treasure is using two numbers — like "three across and four up" — from the corner?”
