Students will see an animated presentation of the proof of the Pythagorean Theorem. This animated PowerPoint presentation uses shearing and the invariance of the area of triangles with congruent bases and heights to show a step-by-step geometric proof of the Pythagorean Theorem.

Students learn about and use a right triangle to determine the width of a „pretend“ river. Working in teams, they estimate of the width of the river, measure it and compare their results with classmates.

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 […]

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 […]
