Curated OER
Journey North
Third graders study butterflies and their migration habits. They track butterfly migration and communicate via e-mail with students in Mexico where the butterflies migrate. They write letters to the students in Mexico, as well.
Curated OER
Inventors Timelines
Students create a class timeline using the patent year for their selected inventor or invention. Using a piece of yarn, they physically create a timeline, and create and answer math word problems using the years from the timeline.
Curated OER
Fast Food Survey Using Bar Graphs
Second graders conduct survey and sort data according to categories, construct bar graph with intervals of 1, and write a few sentences about their graphs.
Curated OER
Noughts
Young scholars try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Young scholars apply the symmetries of regular polygons. Students devise ways to critically follow a chain...
Curated OER
The Tiled Courtyard
Fifth graders use the guess and check technique to solve a problem involving transformations. They work with a grid and criteria provided by the teacher to solve a sequence with black and white rows.
Curated OER
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Curated OER
Pocket Change
Students explore algebraic relationships using the coins in their "pocket." Interactive games that demonstrate the use of estimation in algebraic problem solving help them build a framework for understanding word problems in a way that...
Curated OER
Looking into Eratosthenes' Radius of the Earth
Pupils, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the size...
Curated OER
Strawberry Milk
Young scholars work in groups or alone to solve the problem. They use a systematic approach to get all possible answers. They report back to the class with solutions. They may extend their studying using a crate with room for 9 bottles.
Curated OER
Mum's Kitchen Floor
Students discuss patterns on a chess board examining symmetries. They read the problem and then brainstorm for ways to solve the problem. As they complete the floor pattern, they record symmetries that it contains.
Curated OER
Working Together
First graders discuss how people in the community work together to get jobs done and complete a worksheet matching number words for the workers with the correct numerals.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Learners construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
Getting to the Bottom of the Pyramids
Middle schoolers work together to develop logical arguments about pyramids and chain letters. They share their ideas with other groups and create a diagram showing the breakdown. They discuss the results.
Curated OER
Physics: Eigenvalues
Students solve problems by discovering the eigenvalues that satisfy design questions. They explain how relaxing a small angle approximation can change the solution. Students apply the numerical model of pendulumm motion to solve the...
Curated OER
Area of Parallelograms
Seventh graders review the process of finding the area of a rectangle and complete a couple of examples as a class. They discuss what a parallelogram is and what the formula would be for finding its area. They listen to an explanation...
Curated OER
Tessellating Art
Fourth graders create artwork showing their own unique tessellating shapes. They apply the symmetries of a regular polygon and describe the reflection or rotational symmetry of a figure or object. They share their art work with the class.
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
Curated OER
Lots of Squares
Pupils work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.
Curated OER
More No-Three-In-A-Line
Fourth graders read Mary's problem and make sure that they examine it.
After some discussion, let the class work on the problem in their groups.
They then take turns in putting a picture of their arrangement on the board.
Curated OER
Battery Depletion and Piecewise Linear Graphing
Students examine a recent flight of Pathfinder. In groups, they use the information to create a table of values showing the battery charge of the space machine. They predict what the charge would be further on in the mission. They use...
