Painting an irregular figure can be tricky if we don't know the exact area. This interactive presentation reveals that irregular figures can be broken into smaller, simple figures that use the area formulas. Go through two examples,...

There are several ways to estimate the area if the curve does not create nice geometric figures. The presenter introduces the idea of using areas of rectangles to estimate the area under the curve. Pupils use four types of Riemann Sums,...

Expand area problems to incorporate prior knowledge. Pupils begin by reviewing the formulas for finding the area of parallelograms and triangles. The scholars apply previous learning of trigonometric ratios and the Pythagorean Theorem to...

Make it complete. Pupils work through 16 problems to review factoring. The problems consist of straight factoring of polynomial expressions, solving equations by factoring, and applying factoring to real-world problems.

Hit the highlights. Pupils complete 20 problems to review key aspects of skills learned about polynomials. They multiply, divide, and factor polynomials along with determining the zeros of a polynomial. At the end, individuals complete...

Students complete activities for geometric shapes and multiplication. For this multiplication lesson, students watch a video about carpets and square foot multiplication problems. Students then work in pairs to solve the main problem in...
