In this tutorial, „Linear functions of the form f(x) = a x + b and the properties of their graphs are explored interactively using an applet.“ The applet allows students to manipulate variables to discover the changes in intercepts and slope of the graphed line. There are six questions for students to answer, exploring the […]

From Elizabeth Stapel at Purplemath, this module helps students understand how to solve linear inequalities with an introduction to the topic using both inequality notation and a graphic representation to express the inequality.

This set of instructional materials and problems helps students understand ratios and proportions, starting with a simple review and progressing into the more advanced territory of similar triangles

In this session, students will begin to explore the questions „What can be measured?“ and „What does it mean to measure something?“ Students identify measurable properties of objects such as weight, surface area, and volume, and discuss which metric units are appropriate for measuring these properties.

These 20 images give students practice measuring the height and width of various pictures with paperclips. Ready to print, each sheet contains a spot for students to write in their measurement of the pencil, ice cream treat, insect, car, and many other common objects. This is excellent practice for students to explore measurement, what aspects […]
