Running Around a Track I
The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...
Curated OER
Measurement, Perimeter and Area
Pupils explore the concept of measurement. In this measurement lesson, students collect data about themselves such as height, finger length, neck circumference, foot length, and other body measurements. Pupils cut squares of certain...
Curated OER
Geometric Relatioships
Students explore measurements and geometric formulas. In this geometry lesson, students investigate pi as it relates to geometry. They collect data and use a chart to organize the data.
Curated OER
Investigation-On the Surface
Learners compute the surface area of 3 geometric solids to determine the shape of package that would require the least amount of paper to wrap. In this geometry lesson, students work on a two-question assessment embedded in the plan. The...

Tessellations: Use Right Angles To Explain The Tessellation of Objects
Young scholars examine a selection of shapes and identify which shapes tessellate and why. They design and make a pattern which involves translation, reflection, or rotation. Students describe the features of 2-dimensional and...
Curated OER
Naming Angles
In this geometry worksheet, students solve 6 problems in which an angle is analyzed. From 5 choices, students circle the correct math symbol that names the angle. There are no examples or explanations for the symbols, which would be...

Bill's Badge
Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.
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, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their results.
Exploratorium
Measuring and Mapping the Playground
The school playground is a great place to learn about math. Pupils measure the dimensions of a playground using baby steps and individual strides. They use their measurements to create a scale drawing of the playground by applying an...

Overlapping Squares
The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....
Curated OER
Introductory to Area (Squares, Rectangles, and Triangles)
Students explore the concept of finding area. In this finding area lesson plan, students use knowledge of area of triangles to find area of squares and rectangles. Students find area of irregular figures by breaking the figure down into...
Curated OER
Family Activity: Triangles and Quadrilaterals
In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...
