Doing is more effective than watching. Learners use spaghetti to discover the relationship between the unit circle and the graph of the sine and cosine functions. As they measure lengths on the unit circle and transfer them to a...

Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...

Tenth graders plot points on a coordinate plane. In this geometry lesson, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

Young scholars create a quilt, using different patterns. In this geometry lesson, students apply prior knowledge as they use different patterns to help them create a quilt using transformations and geometric shapes.

This lesson introduces students to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Young scholars, after researching the history and foundation of Renaissance rose windows, access ArtEmboss to create an original window design. They employ a basic metalworking technique utilizing a soft metal. The design created...
