The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Pupils work in pairs to investigate what it takes to prove that two triangles are similar. They work through various shortcuts to find which are enough to show a similarity relationship between the triangles. Small groups work with the...

In this math worksheet, students state the tests for convergence or divergence of a series. Then they apply the tests of convergence and divergence.

A five-lesson unit challenges teams to design a complex to allow people to colonize the Moon. The teams first work in order to understand the challenge before becoming experts. Expert teams learn about different aspects needed to survive...

Sixth graders examine how to select samples and apply them to an experiment. In this sampling lesson, 6th graders use a bag of yellow and blue cubes to take a sample. They predict how many of each color there are the bag. They set up and...

Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

Middle schoolers are introduced to a problem involving an environmental issue. They are introduced to the capture-recapture method which involves capturing fish, tagging them, returning them and recapturing another sample. Pupils work...

Mathematicians compare triangles at different scales. In this geometry lesson plan, high schoolers calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles are...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

Middle schoolers examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Pupils incorporate their conceptual understanding of proportions to write a creative piece similar to the example poem.

Seventh graders use the internet to investigate the salaries of professional football players. They calculate how much the top five paid athletes in football earn for one game and for one minute of playing time. Students determine the...

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, students need to determine...

Explore rational numbers with the young mathematicians in your class. They will investigate decimals, fractions, and percents before ordering and comparing rational numbers. This multi-day unit includes differentiation activities and...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

Learners estimate the total number of species in Ecuador using the capture/recapture method. They collect data about each species and act as members of a science expedition to determine the total number of species by using mathematical...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

Warm-up pupils' fraction muscles with a four-question quiz, then delve into a learning game designed to reinforce the concept of simplifying fractions. Based on the "I do, We do, You do" method of teaching, the lesson directly...

Eighth graders follow a recipe, focusing on the concepts of ratio and proportion, to mix a batch of icing. They decorate cupcakes in the form of a pumpkin.

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...
