Scholars show what they know about data collection and analysis with an activity that examines a smaller population of Houghton, Texas. Independently or in pairs, learners identify their research question, gather, graph, and analyze...

Convey to your pupils the importance of units, then show how to use dimensional analysis to perform a unit conversion. The math lesson includes detailed worked-out solutions to guide learners in their practice.

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students work on different mathematical skills that align with state standards. The skill of problem solving is done with reasoning and communication is made to students through solid brain connections to the math concepts.

Students investigate currency and exchange rates.  In the middle school mathematics lesson, students use ratio and proportion to convert from Australian currency to the U.S. dollar and vice verse.  Students create their own...

Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.

Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.

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...

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

Students explore numbers, computation, ratios, proportions, probabilities, statistics, and money in this six lessons unit. Practical applications in the real world are emphasized through an interactive approach to math in these lessons.

Students explore the concept of percentages. For this percentages lesson, students find the percentages of various colored m&m's in their bags. Students find the cost of items before and after a discount. Students use proportions to...

Ninth graders gain an application level understanding of probability, symmetry, and ratios and rates that exists in one's everyday environment relative to human genetics.

Learners use cross-multiplication to find the unknown respiration rate of an astronaut. In this multiplication lesson plan, students also use the same process to find missing values in proportions.

Students figure out the mileage from one state to another using a map. In this map lesson, students look at the scale factor and turn it into a fraction. They measure the distance between two cities and use the proportion to find the...

Students examine how driving a hybrid car can save money and cut down on pollution.  In this hybrid vehicles lesson students complete an exercise that shows them how to work with proportions, percents, dimensional analysis and...

Students determine the length and width of leaf samples to the nearest millimeter and the circumference of trees. They participate in a discussion about the importance of collecting specimens carefully. They compile accurate...

Learners identify and use properties of similar figures. In this geometry instructional activity, students use proportions of the sides of triangles to solve triangular relationships. They use soda can as their visuals.

Young scholars examine and discuss typical linear equations, and the difference between a linear and nonlinear equation. They observe examples of linear equations and complete a worksheet.

Sixth graders express numbers as percents greater than 100 and less than one. In this lesson on percents, 6th graders work in groups with real life scenarios to develop an understanding on percentages greater than 100 and less than one....

Students demonstrate fraction symbols. In this fractions lesson plan, students use paper strips to represent various fractions. Students then use fraction circles to compare various given fractions.

Learners read different scenarios and discuss how to add fractions. in this addition of fractions lesson plan, students learn how to add unlike fractions and practice 4 problems.
