"Sir Cumference and the First Round Table" by Cindy Neuschwander
Students analyze characteristics of various 2 dimensional shapes and explore their properties and use various vocabulary terms to discuss geometric relationships.
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
Prime and Composite Numbers, Prime Factorization
Students research prime and composite numbers. With a partner, students use graph paper to draw rectangles of various sizes. They list the dimensions of rectangles and discuss how the dimensions relate to the factors of each number....
Curated OER
Pythagorean Circles
Pupils solve problems using smaller steps. In this geometry lesson, students find the diagonals of rectangles and the area of the annulus between two circles. They are given the starting point and the radius.

Describing and Creating Plane Figures - Grade One
Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...
Curated OER
Rectangular Gardens
Students create a rectangular garden using paper and tiles. In this geometry lesson, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the rectangles creating a...
Curated OER
I Can Build It.....Yes I Can!
Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson would be an excellent choice for...
Curated OER
Exploring Area
Fifth graders explore the concept of area using the geometry of selected objects. The laboratory for this experience is the classroom. The lesson plan focuses upon the objects that have four sides like squares and rectangles.
Curated OER
Area and Perimeter
Pupils participate in a hands-on activity that shows the independence of perimeter and area for simple irregular figures.
Curated OER
Dilations of 2 and 3 dimentional figures and their effect on area, surface area, and volume.
Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry lesson plan, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their...

Chapter 8 Extra Problems Worksheet: Similar Triangles
In this similar triangles worksheet, students solve 6 similar triangles. Students use proportions to solve similar triangles and similar rectangles.
Curated OER
Midpoints and Bisectors
In this geometry worksheet, learners calculate the midpoints of polygons using coordinate pairs. They find the angle bisector, altitude and median of the given triangles. There are 33 questions.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Connections Involving Geometry And Inequalities
In this math worksheet, students investigate inequalities using problems like: If x and y are randomly determined so that 1 < x < 3 and 4 < y < 7, then what is the probability that | x – y |< 4?
Curated OER
The Great Cover Up!
Young scholars use non-standard measurement tools such as body parts, beans and counters to find the area of shapes drawn on the floor. They continue to determine the area of other objects in the classroom.
Curated OER
Volume
Students, after reviewing the measuring of the lengths of sides of different shapes along with the calculation of their perimeters and areas, encounter what it means by the 'perimeter' of a polygon. They practice measuring units of...

Proving the Pythagorean Theorem
Students solve problems using the pythagorean Theorem. In this geometry lesson, students complete proofs using the Pythagorean Theorem. They share their proofs and solutions with their classmates and family members.
Curated OER
Building Shapes From Numbers
Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.
Curated OER
Graphing Data
Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They calculate the volume, area and perimeters of the shapes created on a coordinate plane.
