In this triangles learning exercise, students solve 4 multiple choice problems. Students find the centroid, orthocenter, incenter, and circumcenter or various triangles.

Tenth graders explore the properties of the incenter of a triangle. In this geometry lesson, 10th graders construct a triangle and the angle bisectors of each angle. The dynamic properties of Cabri Jr. allow students to locate and...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

Students listen to the story, Earth Day - Hooray!, and discuss the story as it is being read.  In this Earth Day instructional activity, students discuss incentives and penalties in regards to taking care of the Earth.  This...

Students discuss the incentives and opportunity costs of spending vs. saving. They follow an interactive website which shows them the how much money they could end up with by saving instead of spending.

What's so special about tangents? Learners first explore how if a circle is tangent to both rays of an angle, then its center is on the angle bisector. They then complete a set of exercises designed to explore further properties and...

You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

Tenth graders find the incenter of a triangle. In this geometry lesson plan, 10th graders define the way to create an incenter with an angle bisector. They differentiate between incenter and incircle.

Students explore the concept of the rise of big business in the United States. In this economics lesson, students investigate the impact of tariffs on businesses. Students also investigate the impact that incentives have on special...

High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This lesson requires the use of Cabri, Jr.

Learners explore profit and risk. In this economics lesson, students read about McDonald's and Nabisco stock and discuss the risks and rewards of stock ownership. Printable worksheets ask questions about rights of stock owners and the...

Learners assess both negative and positive incentives associated with credit card use. They identify profit as an economic incentive for banks to offer credit cards.

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Challenge the class with inscribed circles in triangles. The assessment task requests class members use their knowledge of circles and right triangles to prove two triangles are congruent. They go on to utilize their knowledge of...

It's all about location, location, location. Small groups work to find the best spot for a rec center to serve three different communities. Learners construct the inscribed and circumscribed circles of a triangle to find the best place....

Students explore investing and saving. In this investing lesson, students identify their own financial goals and hurdles to success, calculate interest, and simulate banking and investing transactions. Incentive certificates, a quiz, and...

Students complete a worksheet that asks them to calculate the true energy cost of various appliances. They compare appliances with energy saving features, rebates and other economical incentives.

You and your learners will enjoy having a nicely organized, typed up unit circle, all filled in with degrees and radians as well as cartesian coordinates. 

Students use economic reasoning to analyze both the short-term and long-term benefits and opportunity costs of educational choices, identify incentives that may influence students' career decisions and solve an "economic mystery"

There are endless uses for printable play money in your classroom, and you'll definitely want to check out these well-designed, attractive printables to add to your bank of manipulatives.

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

In this geometry worksheet, 10th graders solve problems involving the perpendicular bisectors and angle bisectors of a triangle and their points of concurrency.  The one page worksheet contains sixteen questions.  Answers...

Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.
