# 5.7 Shapes on the Coordinate Plane

## Unit Goals

• Students plot coordinate pairs on a coordinate grid and classify triangles and quadrilaterals in a hierarchy based on properties of side length and angle measure. They generate, identify, and graph relationships between corresponding terms in two numeric patterns, given two rules, and represent and interpret real world and mathematical problems on a coordinate grid.

### Section A Goals

• Locate points on a coordinate grid.

### Section B Goals

• Classify triangles and quadrilaterals in a hierarchy based on angle measurements and side lengths.

### Section C Goals

• Generate, identify, and graph relationships between corresponding terms in two patterns, given a rule.
• Represent and interpret real world and mathematical problems on a coordinate grid.

### Glossary Entries

• area

The number of square units that cover a flat figure without gaps or overlaps.

• axes
The numbered lines on a grid.

• coordinate grid
A grid containing the horizontal and vertical axes.

• coordinates
A pair of numbers that shows an exact position on a grid. The first number represents a position on the horizontal axis and the second number represents a position on the vertical axis.

• cubic unit
A unit cube with side lengths that are standard measurement units that is used to measure volume.

• horizontal axis
The number line that runs from left to right in a pair of axes.

• power of 10
The result of multiplying 10 by itself a given number of times.

• rectangular prism
A solid figure which has six faces that are rectangles.

• right triangle
A triangle with a 90 degree angle.

• unit cube
A cube whose sides are 1 unit long, used to measure volume.

• vertical axis

The number line that runs up and down in a pair of axes.

• volume
The number of unit cubes that fill a solid figure without gaps or overlap.
