Introduction Points
In this math activity, middle schoolers find the points on the Cartesian plane. The graphs use the color green and red to differentiate the positive and negative points.
Curated OER
Robot Cartography
Students identify points plotted on the coordinate plane. In this geometry lesson, students learn to read a map using concepts of a coordinate plane grid. They find the path given a map to tell them where to go.
Curated OER
Melissa's Garden
In this math activity, students identify the location of pictures on a coordinate plane. They write some answers as an ordered pair. They read ordered pairs and identify the picture at a specified location. Six problems are on a page. An...
