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 […]

The classroom poster helps students understand fractions as parts of a whole by illustrating pizzas and fractions of pizzas. These eight images show a whole pizza, a pizza cut in half and in quarters with various pieces removed. It is an excellent visual to present students as they dive into more complex understanding of fractions […]

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.
