Thinking in the Three Dimensions
Discover different dimensions with paper folding. Pupils first read about zero, one, two, and three dimensions, and then learn about the fourth dimension, time. They then use origami to create models of shapes in three dimensions and use...

Triangle Sum Theorem
Your visual geometry learners will appreciate triangle drawings as they model the triangle sum theorem and algebraically solve to find the missing interior angle in a triangle. Practice problems increase in complexity and vary in their...
Curated OER
Fill the Number Grid
Patterns emerge as the class works together to fill in a number grid. This whole group activity is designed to make all learners feel successful, and ultimately turns into a activity on the least common multiple.
Curated OER
ABC's Transformer
Fourth graders design their own letter graph, and then produce the resulting graphs after a translation, reflection, and rotation. After a review of vocabulary, 4th graders create their graphs using crayons.
Curated OER
Folding to Make Shapes
Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...
Curated OER
The Pythagorean Theorem, the Distance Formula, and Slope
Students explore the concept of the Pythagorean Theorem. In this Pythagorean Theorem lesson, students derive the distance formula and slope of a line from the Pythagorean Theorem.

Problem Solving with Fractions
Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson plan includes essential questions, vocabulary, a materials list, and links to related units.
Curated OER
Contact Angle. Interfacial Tension and Wetting
Students determine the contact angle of water on different surfaces. In this physics activity, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...
Curated OER
Surface Area
In this geometry instructional activity, 10th graders define surface area, net and lateral face. They calculate the surface areas of cones, prisms and cubes. There are 9 surface area questions.
Curated OER
Measuring Angles
Identifying and measuring angles with a protractor can provide a fun way for students to learn this mathematical concept.
Curated OER
Performing Transformations
Students investigate the concepts relating to creating a tessellation. They include using pattern blocks in order to create interconnecting patterns. Students review translations, rotations, and reflections.
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
Finding the Area of a Parallelogram with Translations
Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.
Curated OER
The Right Angle
In this geometry worksheet, 10th graders determine the answer to a vocabulary questions and then follow the give rules to place the answer in the appropriate place on the crossword grid. The one page worksheet contains 18...
Curated OER
Exploring Earth Through Maps and Technology
In this maps instructional activity, students read 3 pages of detailed information about maps, latitude, longitude, topography, satellites and global positioning. Students then answer 10 questions. There is also a research project...
Curated OER
The Dragon Curve Fractal
Students identify the properties of a dragon curve. For this geometry lesson, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Fly Away With Averages
Students 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
Young scholars 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...
