This math topic focuses on identifying points on a Cartesian grid, specifically in one dimension (either x or y values only, not both). The problems, structured with multiple-choice answers, ask students to identify either the x-value or the y-value of a given point. Each question presents a different set of points with corresponding options for students to match the correct coordinates. This topic is part of a broader unit on Cartesian Grid Foundations, intended to build foundational skills in understanding and interacting with one-dimensional points on Cartesian grids.
