Cool circle patterns! To investigate patterns of shading in circles, learners use the values for specific examples of the pattern to generate a verbal rule for the arrangement.

We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson plan then...

Young mathematicians explore number values by utilizing food as a visual aide. They discuss the differences between halves, fourths, and eighths and how they are visually represented by a pizza. Then create their own pizza in class and...

Even kindergartners can draw triangles in circles, but the assessment task requires a bit more geometric knowledge. Scholars investigate triangles that have a diameter of a circle as one of its sides. They must consider triangles that...

Anyone can draw a square, but can you CONSTRUCT a square? Here is a resource that challenges math scholars to create steps to finish their own construction. They test their ability to read and follow directions to complete a construction...

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Discover the concept of fractions by using fruit as a model. Scholars discover fractions are part of a whole, similar to the pieces of fruit which are placed in front of them. They then cut up several different types of fruit and discuss...

Students calculate the area and circumference of a circle. In this geometry activity, students solve word problems with circles and create formulas to calculate the area. They find the rate and complex area of a circle.

Gobble up a slice of the task. Scholars first consider the area of a whole pizza, half a pizza, and a quarter of a pizza. They then consider other central angles and develop a formula for the area of any sector of a circle.

Exactly how fair are the board games children grow up playing? Young mathematicians investigate this questions as they work their way through this five-lesson series on basic probability. 

Students explore measurement in terms of pizza toppings. In this math lesson plan, students draw a circle using string and a ruler, determine areas of different size circles, find how many two topping pizzas can be made using 14...

Students identify different locations on a unit circle. In this precalculus lesson, students identify the different trig properties and rewrite the equation of a circle in standard form. They use mnemonic devices to help them...

Math pupils, by viewing a video, discover the history of pi and some of the applications of its uses in the world today. They conduct an experiment by measuring the diameter and circumference of various circular objects to calculate...

Learners calculate the area and diameter length of a circle. In this geometry lesson, students investigate the use of pivots as they review parts of a circle. They create a circle using cardboard and label all the parts.

Students develop techniques for estimating the area of a circle and use ideas about area and perimeter to solve practical problems. In this area and perimeter instructional activity, students apply the concepts of perimeter and area to...

In this multi-faceted introduction to pi, participants perform a bevy of pi-related activities. Ranging from measuring household items to singing pi songs and reading pi stories, this fun and non-intimidating resource serves to bring up...

High schoolers identify chords and angles. In this geometry lesson, students calculate the length of the chords inside and outside of-the circle. They differentiate between tangent and secant lines.

Middle schoolers create a spreadsheet to record information about circular objects. They measure and record information from a variety of objects. Students calculate the ratio of the circumference to the diameter of each object. They...

Sixth graders inspect M&M's to complete statistical data. Students interpret percent of colors represented. They convert data from decimals, fractions, and percents. Using the data, 6th graders create a bar graph and a circle graph.

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson plan. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber...

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

High schoolers identify the relationship between angles and arcs. In this geometry lesson, students rotate and move the circle around to create different arcs on the TI-Navigator. They differentiate between major and minor arcs.

Learners differentiate between the different properties of arcs, arc lengths, chords, and chord lengths. In this circles lesson, students calculate the arc length of a given circle, and find the measure of the inscribed angles of a...

Students define an arc and calculate its length. For this geometry lesson, students find examples of arc in the real world. They show their understanding of arcs through problem solving.
