You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

There's only one way to multiply, right? Not when it comes to polynomials. Reach each individual by incorporating various representations to multiplying polynomials. This lesson approaches multiplying polynomials from all angles. Build...

Guide your class through the intricacies of solving compound inequalities with a resource that compares solutions of an equation, less than inequality, and greater than inequality. Once pupils understand the differences, the...

Be ready mathematicians of every level. This lesson plan leads to the discovery of the zero product property and provides challenges for early finishers along the way. At conclusion, pupils understand the process of using the zero...

How big is the biggest pumpkin you've ever seen? Did it weigh over a ton—literally? Young learners view pictures of some record-breaking pumpkins, including some that weighed over 1,300 pounds, before answering five word problems about...

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

Learners will have fun creating a parachute to collect data with. They will construct the parachute in small groups, measure the materials, and create an observation sheet. Then they drop the parachute and make predictions about how long...

Using Wolframalpha graphing capabilites, algebra learners graph polynomials with degrees of three and larger. They identify the roots and graph each polynomial, predict zeros and shapes of graphs, and validate their understanding through...

Kids gain a deeper understanding of mathematical symbols, by playing an interactive game using flash cards. They complete an attached Missing Symbols Worksheet, flash card and an assessment are also included.

Learners gain an understanding of how the powers of 10 and scientific notation can be used to represent the scale of things in the universe. They relate the number of stars in the universe to the number of grains of sand on Earth's beaches.

Learners explore the concept of probability. They calculate the probability of an event happening and graph their results. Students determine the probability of winning a sweepstakes. They construct a bar graph to represent all the...

Patterns emerge as the class works together to fill in a number grid. This whole group activity is designed to make all learners feel successful, and ultimately turns into a lesson on the least common multiple.

Investigate perimeter and area of polygons! In this measurement lesson, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.

Dedicate one or two class periods to creating a class glossary of geometry terms. Many geometry terms also appear in our every day vocabulary, but they have very different meanings. For example, the word gross in geometry is very...

Youngsters improve their measuring and counting skills using sunflowers. They view pictures painted by Van Gogh. Everyone works in groups to measure sunflowers and record their findings, and they all use sunflower seeds to create...

Tenth graders investigate the history of Pi and how it relates to circles. In this geometry lesson, 10th graders measure the circumference of a circle and the diameter of a circle. They relate these measurements to the number of Pi or 3.14

What a great way to have pupils apply classroom learning to real-world skills! They complete problems involving the addition and subtraction of decimals related to banking-type questions, and then use a spreadsheet to display their results.

It's time to get crafty with shapes! Your future farmers demonstrate their geometric ability by building a farm using triangles, circles, rectangles, and squares. But first, scholars take part in a brainstorm session inspired by their...

Reinforce the concept of probability with a series of lessons highlighting the idea of likelihood, probability formulas, relative frequency, outcomes, and event predictions. The collection is made up of four lessons offering informative...

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

Using a similar process from the first instructional activity in the series of finding area approximations, a measurement resource develops the proof of the area of a circle. The problem set contains a derivation of the proof of the...

How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and...
