What are the Odds
Students predict the-outcome of an event. In this algebra lesson, students compare and contrast the probability of an event occurring. They calculate the odds of a simple event and make estimation.

Alike and Different
Learners compare and contrast objects and are introduced to a Venn Diagram. In this alike and different lesson, students make observations regarding properties of objects. Learners classify object and build ideas about variables....
Curated OER
The Topsy-Turvy Twins
Fourth graders read the problem and brainstorm for ways to solve the problem - list these on the board for the students to refer to as they solve the problem. They work in pairs and focus on the strategy selected.
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Buying vs. Leasing Car
Young scholars use the Internet and worksheets to calculate the costs, advantages and disadvantages to buying or leasing a car. They write a summary of their investigation and decide which option they think is better.

Foreign Stamps
Eighth graders convert the price of US stamps to those of a number of foreign currencies. They use conversion charts to make the changes.
Curated OER
Cinderbank
Fourth graders identify major components of a "Cinderella" story in order to create a database.

Closer To the Ground Lesson 2: Providing a Helping Hand
Students examine how businesses and corporations contribute or sponsor activities for the common good. They read annual reports of major corporations to determine how they contribute to focused activities for the common good.

The Truth About Triangles and Squares
Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.

Creating Polygons
Young scholars describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

How Many Bears in the Forest?
Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
