Properties of Fractals
Young scholars build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...
Curated OER
Patterns in Fractals
Students explore the concept of fractal patterns. For this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...
Curated OER
Pythagorean Theorem
Young scholars solve right triangles using the Pythagorean Theorem. For this solving right triangles using the Pythagorean Theorem lesson, students find the missing side of a right triangle. Young scholars find the hypotenuse...

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.
Curated OER
Million Dollar Gift
Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.
Curated OER
Donut Dinero
Students set up a classroom currency exchange and explore the idea of bartering to get what they want. They create a monetary unit that is based on fractions and multiples of a standard unit, and compare this system to the U.S. monetary...
Curated OER
Cannot Buy Me Love
Young scholars investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and...
Curated OER
Tortillas
Learners convert recipes for tortillas. They calculate the amounts of ingredients as they convert recipes and write an explanation of the task to demonstrate their calculations. After reviewing their calculations, they demonstrate how...

Grade 2: Texas Problem Solving
Second graders use numerical data about Texas to write and solve real-life problems involving addition and subtraction (or multiplication and division). They work in pairs to choose three numerical facts about Texas to use to make up...
Curated OER
Two-Step Equations
Students explore the concept of solving two-step equations. In this solving two-step equations lesson, students watch a short video about solving equations. Students view a PowerPoint presentation about solving two-step equations....
Curated OER
Circles and Clocks, Shapes and Time
Students work in groups to research clocks and practice telling time. In this telling time instructional activity, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles...

Plan a Cruise Lesson Plan
Young scholars measure distances and report them in fractions, convert fractions to decimals, and multiply decimals.
Curated OER
Angles Lesson Plan
Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.
Curated OER
Irregular Fractals
Middle schoolers 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.
