Connecting Formulas Related to Geometric Figures

Young scholars explore how to solve any quadratic equation with a video about the quadratic formula. They then use the quadratic formula to solve a set of quadratic equations.

This unit on connecting algebra and geometry covers a number of topics including worksheets on the distance formula, finding the perimeter and area of polynomials, the slope formula, parallel and perpendicular lines, parallelograms,...

Formulas and procedures for finding the area and circumference are not provided on this handout, so it will be best used as a practice of already-acquired skills. It is a well-rounded assignment, however, as it includes diagrams,...

Turn up the volume in 3-D. The video introduces the concept of volume and the units used to measure it. Using a graphical representation of translating 2-D figures, the resource develops the formulas for finding the volume of prisms and...

Is prism just another mathematical term for a solid? It must be since this lesson is about volume. The teacher illustrates and explains how to find the volume of a rectangular prism and also how to find the volume of a triangular prism....

Build an explicit formula using tiles. Pupils develop a tile representation of a term within a sequence given figures of previous terms. Using the diagrams, learners develop the explicit formula by recognizing the common difference and...

Trying to find the volume of a composite figure? Wait! What's a composite figure? A composite figure is a combination of familiar simpler figures. So the composite figure can be taken apart and represented as the simpler figures in order...

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Make a parallelogram out of two trapezoids to find the area of one trapezoid? Sounds pretty complicated. Well, it's not complicated but there are a lot of steps. The instructor does a pretty good job of diagramming and explaining just...
