Area of a house

CC_BY-NC-SA

Goal: The goal of this activity is for students to find the area of a house floor plan. They will need to use their knowledge of rectangles to identify the missing side lengths to find the correct area. This also allows students to see how area is used in a real-life application.

2015 Excellence in Mathematics Contest

CC_BY-NC

This is the Team Project from the 2015 Junior High Excellence in Mathematics Contest at Chandler-Gilbert Community College. It involves lots of open ended problems from many mathematical areas: Find the weight of a snowman (geometry, proportional reasoning) Find how long it takes ice to form on a lake (rate of change, awkward units) Questions about the amount of mining done in Northern Minnesota (proportional reasoning, conversions) You can use just one part or all parts depending on the audience and the purpose.

Earth Day Math

CC_BY

This powerpoint presentation for Earth Day Mathematics Lesson touches on many mathematical concepts such as volume, estimation, mean (average), measurement, and unit conversion. Students work in cooperative groups to find the approximate volume of rubber that a small business has 'rescued' from a local landfill. Alternate application ideas provided.

Proving the Pythagorean Theorem with Geogebra

CC_BY-NC-SA

The Pythagorean theorem is one of the most important concepts in all of mathematics. This activity uses Geogebra to help students see why the relationship between the sides of a right triangle are as they are.

Pythagorean Theorem Investigation: It's As Easy As… a, b, c

CC_BY-NC-SA

Oftentimes, the Pythagorean Theorem is taught from the standpoint of, "Here is the formula, let's practice finding the lengths of the sides of triangles!" without helping students understand or develop the relationships between the sides on their own. This activity helps students experience those relationships using multiple approaches, prove why the theorem is true, and practice using it.

Directed Distance - An Introduction to "Graph"

CC_BY-NC-SA

This annotated lesson can be used to introduce directed distance and the concept of graph. It can be used as the very first experience students have with graphs, as a review, and/or as an introduction to “circular” coordinates (you can choose to never refer to them as polar coordinates). It is highly interactive and connects the concepts of “new” graphing systems to rectangular coordinates. Initially, there is a brief history given and review of the Cartesian rectangular coordinate system.

Proportional Relationships of Triangles - An Activity

CC_BY-NC-SA

This is a two-part activity and will most likely take two 50 - 55 minute class periods – one day per part. Part I (Day one) is a hands-on activity that allows students to work together on computers to discover the proportional relationship between a pair of similar right triangles. Ideally, you will have a class set of computers or a computer lab you could use for this lesson. If you don't have access to these resources you can run a demonstration on one computer and project it for the class and have students come up to manipulate the triangles.

A Bug's Life - Estimating Area of Irregular Polygons

CC_BY-NC-SA

This is a creative writing project that includes a rubric for scoring student's work. It works well as a team project. The focus of the project is on solving a contextual problems involving area of a two-dimensional object composed of triangles, quadrilaterals, and polygons.
