Geometry and Quilting
Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...
Curated OER
Area
Learners solve problems involving area. In this geometry activity, students calculate the area of an object and relate it to the area of the ocean. They define what exactly and area is and then solve problems relating to the real world.
Curated OER
What a Square
Young scholars 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
Square Circles
Students analyze and demonstrate how a circle can be measured in square units and examine how diameter, circumference and radius are related.
Curated OER
Area graphics for 7th graders
Students randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.
Curated OER
Moving On: Octagoning the Circle
Students explore circles through the use of octagons. They inscribe a circle in a regular octagon and find the area and perimeter of the hexagon with respect to the radius of the circle. Students present their findings to the class.
