Plotting points in the first quadrant

PROCEDURAL
Mathematics›Geometry|Ages 10—11|ID: mt_snlqRCiA1R

Plot and read ordered pairs in the first quadrant of the coordinate plane; represent real-world and mathematical problems by graphing points and interpreting coordinate values in context

Mastery Evidence

  • Plot the point (4, 7) accurately on a first-quadrant grid
  • Graph a set of data pairs (e.g. time vs distance) as points on the coordinate plane
  • Read coordinates of a plotted point and explain what they represent in a given scenario

Assessment Prompt

“If you tell [child] a car journey passes through grid points (2, 3), (5, 7), and (8, 4) on a map, can they plot those points and describe what the journey looks like?”
