Students complete nine fill-in-the-blank problems about triangle base lengths, coordinate patterns moving right by a fixed amount, and the next point in a diagonal pattern. The matching activity pairs four descriptions — a line rule, a horizontal line, a shape, and a midpoint — with their coordinate answers.
Extending coordinate patterns and matching rules to graphed lines connects the coordinate plane to algebraic thinking and prepares students for middle school function reasoning.

Coordinate Plane
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A triangle has vertices at (1, 1), (5, 1), and (3, 5). The base along the bottom is 4 units long.
2. A pattern starts at (1, 2) and each point moves 2 units right. The third point is at (5, 2).
3. Points are plotted at (1, 1), (2, 2), (3, 3), and (4, 4). The next point in the pattern is (5, 5).
4. A path goes from (0, 0) to (3, 0) to (3, 4). The total distance traveled is 7 units.
5. A shape has corners at (2, 1), (6, 1), (6, 3), and (2, 3). This shape is a rectangle.
6. Points at (1, 3), (3, 3), (5, 3), and (7, 3) all share the same y-coordinate.
7. A pattern starts at (0, 1) and moves 1 right and 2 up each step. The second point is at (1, 3).
8. Using the same pattern, the third point is at (2, 5).
9. A square on the grid has corners at (3, 2), (7, 2), (7, 6), and (3, 6). Its area is 16 square units.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Points (1,2), (2,4), (3,6) follow the rule: y =
→ 2 times x
(4, 5) and (1, 5)
A horizontal line through y = 5 passes through
→ (4, 5) and (1, 5)
square
Shape with 4 equal sides and 4 right angles
→ square
(3, 0)
Point exactly halfway between (0, 0) and (6, 0)
→ (3, 0)
2 times x
