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.

Conjectures and Conclusions
Learners draw conclusions and make conjectures given a specific scenario. In this geometry lesson plan, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is what it is.

Light Beam
Students measure and convert between units. For this geometry lesson, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.

Polynomial Divisions
Young scholars factor polynomials and use long division t solve problems. In this algebra lesson, students find the zeros of polynomials by synthetic and long division. They perform operation using complex numbers.

Amusement Park Physics
Students get up close and personal with principles of motion. For this physics lesson, students collect and analyze acceleration data on amusement park rides. Students use CBLs to collect data in this lesson.

Exploring Centers of Triangles
Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.
