Unpacked Content
Knowledge
Students know:
- Terminology associated with coordinate systems.
- Correct construction of coordinate systems.
Skills
Students are able to:
- Graph points corresponding to ordered pairs.
- Represent real-world and mathematical problems on a coordinate plane.
- Interpret coordinate values of points in the context of real-world and mathematical situations.
- Determine lengths of line segments on a coordinate plane when the line segment joins points with the same first coordinate or the same second coordinate.
Understanding
Students understand that:
- A variety of representations such as diagrams, number lines, charts, and graphs can be used to illustrate mathematical situations and relationships.
- These representations help in conceptualizing ideas and in solving problems.
- Distances on lines parallel to the axes on a coordinate plane are the same as the related distance on the axis (number line).
