Curated OER
Perimeter
Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.
Curated OER
Symmetry of Road Signs
Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.
Curated OER
Transformations and Rotations
Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
Curated OER
Octagon Lesson Plan
Students investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.
Curated OER
Fractions Describe Parts of a Whole
Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...
Curated OER
Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...
Curated OER
Translating Transformations in Geometry
Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
Curated OER
Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...
Curated OER
What's Your Design?
Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.
Curated OER
Exploring Volume of Cylinders
Tenth graders investigate the volume of a cylinder. In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions. The lesson progresses to the use of the formula to find the...
Curated OER
Problem Posing Mathematics
Learners work on multiplication problems. In this hands-on math lesson, students practice the concept of multiplication through manipulatives, arrays, pictures, and drawings. They discover other ways of learning multiplication besides...
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Cracks on the Walls
Young scholars observe the cracks in school walls and pavements. For this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.
Curated OER
You Can Count on Squares!
Fourth graders engage in and explore to develop mathematical, specifically algebraic, ideas. Although the tasks are built around measurement, they are algebraic to the extent that they require 'formulae' to be derived form the geometric...
Curated OER
Fly Away With Averages
Learners discover the process of finding the mean, median, and mode. Through guided practice and problem solving activities, they use a computer program to input data and create a graph. Graph data is used to calculate the mean,...
Curated OER
Fly Away With Averages
Students study mean, median, and mode. They construct paper airplanes and test them to see how far they fly. They measure the distance and then find the averages of their throws. They use spreadsheet software to record the data in a...
Curated OER
Distortion Unleashed
Learners view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...
