Sir Cumference and the Dragon Pi
Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and then consider...
Curated OER
Angles and Arcs
Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs.
Students give examples of concentric, similar, and congruent circles and congruent arcs.
Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.

Investigating Pot Sherds
Sixth graders measure pot sherds and use their knowledge of Pi to infer possible uses of pottery. They also infer possible functions of ancient ceramics. After tracing rounded pottery pieces onto paper, 6th graders use compasses to...
Curated OER
Math: Arcs and Chords
Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...

Geometry Worksheet: Area (6)
In this geometry learning exercise, 10th graders express the area of the ring between two concentric circles in terms of the length of a segment tangent to the smaller circle. The one page learning exercise contains a drawing of and an...
Curated OER
Geometric Figures
Young scholars compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.
Curated OER
Modeling Permutation Group
Students explore the concept of transformations. In this transformations lesson, students construct an equilateral triangle and a square with a circumscribed circle. Students reflect and rotate their constructions.
Curated OER
Around and Across
Tenth graders investigate the circumference and diameter of a circle. For this geometry lesson, 10th graders relate circumference to diameter. They create a scatter plot to estimate the value of pi.
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
Curated OER
Geometry: Area
Students visit various websites to calculate the area of circles, triangles, rectangles, trapezoids, and parallelograms. They explore math problems and play interactive games dealing with geometry.
Curated OER
Which Word Matches the Image? #2
In this math worksheet, students learn to match the name of a geometric figure with the picture. Students examine a drawing of a geometric shape, then circle the word that matches it.

Worksheet 1, Coordinate Graphing
In this algebra worksheet, students determine the quadrant a given point is in. They find the midpoints of two line segments. Students plot points to form a triangle and find the distance between points. Students find the area of the...
Curated OER
Creating Tessellations
In this creating tessellations worksheet, 10th graders solve 2 word problems that include creating various tessellations. First, they explore the various techniques used to form tessellations, including triangles, quadrilaterals,...
Curated OER
Symbol Search
In this visual thinking activity, students analyze 50 different symbols in a grid. Students must find 10 specific symbols in the puzzle and color or circle them.
Curated OER
Same Worksheet
This basic shapes worksheet has students look at the shapes in 3 rows, and circle the shape that is the same as the first shape in each row. Very basic shape recognition.
Curated OER
Perimeter and Area of 2D Shapes
Young scholars find the perimeter and area of circles, triangles, and rectangles. For this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no...
