Young scholars identify the slope of a line given two points on the line. In this algebra lesson, students solve linear equations by finding and comparing slopes of lines. They differentiate between the steepness of the slope and the line.

Fifth graders accurately measure the distance to eight points on an uneven surface by conducting a simulation of sattelite altimetry. They create a two-dimensional model of the simulated ocean surface by graphing data from the Radar Run...

Students compare and order integers on an umber line. In this algebra lesson, students differentiate between positive and negative numbers. They plot point in the correct order on a number line.

Students study conservation and how cities obtain their water.  In this water lesson students view a PowerPoint presentation and draw a picture of the water cycle.
