Spaghetti Measure
Students receive a copy of a "Spaghetti Measure" task sheet along with the scoring rubric. Students preview the task and the rubric prior to starting the task. tudeThey determine the circumference of a circle of spaghetti that will...
Curated OER
Around and Around
Students 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 find the...

It's My Time!
Students create a pie chart. In this time lesson, students determine the amount of time they spend on given activities. They create a pie chart diagraming the data. Students share their graphs with the class.
Curated OER
Measurement
Students identify and categorize different problem situations or contexts using one of four measurements to solve the problem. Through guided and independent practice, they discover ways to determine which measurement to use when...

Segments Formed by Intersectiong Chords, Secants, and Tangents
Learners investigate the properties of segments formed which chords, secants, and tangents, intersect. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding segment relationships.

Similarity
In this similarity worksheet, 9th graders solve and complete 6 different types of problems. First, they complete the statement in the box shown. Then, students determine whether they agree or disagree with the statement and given...
Curated OER
Round and Round--Wheels and Axles
In this wheels and axles worksheet, students read a 1 page article, make a list of how many objects they can find or think if that uses a wheel or axle and then design their own machine.
Curated OER
Volume Word Problems
In this volume worksheet, 10th graders solve 10 different word problems that include determining the volume in each one. First, they determine the ratio of their radius given the cubic meters of a sphere. Then, students determine the...
Curated OER
Properties of the Centers of a Triangle
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.
Curated OER
Time Management: Piece of Pie
Students examine their own lives and how well they manage their time outside of school. In this this time management lesson, students discover the amount of time they spend on other activities, and create a pie chart with that...
Curated OER
Putting the 'pi' in Pumpkin Pie
Students use geometric formulas to divide a pumpkin pie. In this geometric formulas lesson plan, students review equations for area and circumference of a circle and divide a pumpkin pie to practice the formulas. Students use the...
Curated OER
Round The Track
Fourth graders develop problem solving skills while learning to measure an athletic track. The focus upon logic and reasoning is helpful for all types of science and math calculations.
Curated OER
Geometry Review
Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...
Curated OER
Triangles with Collinear Circumcenters
Students identify the circumcenter of a triangle. In this geometry lesson, students construct a perpendicular bisector using a straight edge and a compass. They differentiate between triangles and collinear points.
Curated OER
Properties of Shapes
In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.
Curated OER
History and the Approximations of pi
Middle schoolers investigate Pi. In this mathematics lesson, learners discuss the history of Pi and determine how the approximation of Pi was discovered.
Curated OER
Around We Go
Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?
Curated OER
What a Square
Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.
Curated OER
The Internet Pizza Server - Pizza Simulation
Learners simulate going to a pizza restaurant, ordering a pizza, and determining whether a small, medium, large, or family size pizza is a "better-buy." Students calculate the price/per/topping and determine whether this price is "fair"
