Juxtaposing the architecture of Ellis island with that of the proposed Trump Wall creates many opportunities for mathematical analysis and frames a discussion of how our nation’s attitude toward immigration has changed
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.
This lesson is the first in a series of four lessons which will help build an understanding of area and perimeter by using real world applications in order to build a skateboard park.
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
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 Read more
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.
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 Read more
