Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

In the first installment of a 21-part module, scholars build on previous understandings of probability to develop the multiplication rule for independent and dependent events. They use the rule to solve contextual problems.

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

Don't discount how much your pupils understand percents! The 27th lesson in a series of 29 presents a problem to find the cost of a discounted outfit. Small groups determine either the original price or the discount received given the...

Your statisticians examine the characteristics of conditional probability and the probability of simultaneous independent events. They perform computer activities to find probabilities for simple compound events. They examine the...

Explore business problems through mathematical analysis. The task has individuals write and graph a linear system to determine the best business model. They use their models to answer a series of questions that help to make a conclusion.

Students raise their design awareness about construction considerations for large public facilities including safety, accessibility, funding, construction materials, and space, use geometry and other mathematical skills to calculate size...

In this math PowerPoint, the process of adding fractions with unlike denominators is broken down into a logical, easy-to-follow sequence of steps. Definitions and examples of multiples, least common multiple, and least common denominator...

Unifix cubes are wonderful tools that can be used to model a variety of mathematical concepts. Children will compose number two through eight by placing Unifix cubes on their paper and then coloring in the cubes they used. 

The AP® exam is not just about the calculations. By reviewing the free-response questions from 2008, teachers and pupils see that several items require justifications and explanations to gain full credit. The chief reader even points out...

The last installment of the 18-part Grade 5 Math Module 1 is an end-of-module assessment. Scholars answer questions that require explaining the connection between powers of 10 and place value, rewriting decimals in different forms,...

Light, distance, and mathematics come together to help scientists plan for space missions. Groups examine the relationship between distance from the sun and light availability in a hands-on exploration activity. They model the inverse...

Eighth graders combine like terms in this properties of variables lesson. Using named items (stars, moons and hearts), they combine like terms using variables. They use the distributive property to combine like terms. Finally, they write...

Show the class how to find the factors of numbers. They use a variety of strategies, including unifix cubes, to find the factors of a whole number. This resource includes clear procedure to follow. Included are an anticipatory set,...

Start with the basics and move up the exponential ladder to master a variety of problem-solving and application problems. The problems are heavy on exponential growth and decay, compound interest, and natural log.  

Watch scholars' understanding of fractions bloom. The resource presents a performance task where the fractions are equal parts from the same whole, and mathematicians must use them to solve problems about a grade level garden. Teachers...

Introduces addition of decimals by using unit notation to represent the problem. Pupils use a place value chart to decompose the numbers and then add before connecting to the standard algorithm. 

Explore how the study of diseases and epidemics can be comprehended from a mathematical perspective. Investigate finite geometric series, calculating threshold values, and statistical models of the spread of disease. How many makes it an...

Pupils solve multi-step number stories. They create number models to solve number stories.  Everyone chooses the appropriate operation to use after reading the problem, and then work in small groups to...

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Third graders demonstrate models to represent a 3 digit counting number. They use manipulative materials to represent place value in whole numbers. Students represent numbers in expanded notation.
