Does the media shape people's views on gender? Scholars use data on gender portrayal in magazines to explore the idea. They use a spreadsheet program to create bar graphs and perform a chi-square test. They also use provided data to...

Learners make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

What's next in the series? Mathematicians study figures, graphs, and statements to determine what comes next in this patterns worksheet. They experiment with a multiplication chart and draw their own figures to continue specific...

Fourth graders use inductive reasoning to find algebraic patterns in geometric figures. They use technology (i.e., calculators, computers) and manipulatives to discover number patterns involving geometric concepts. They solve concrete...

Use this video to show your learners an example of how to translate word phrases into an equation to solve a real-world problem. The presenter begins with a review of how to use cross products to solve a proportion, including how to do...

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Students locate an area of marsh and, by measuring the total number of individual plants in a sample area, determine whether purple loosestrife population density is correlated to the total plant diversity of the community. They...

Functions behaving badly: the squaring function and the absolute value function are both zero at x=0. Yet when you divide each by x, different things happen. Here, your class will explore each scenario as a means to adding depth to their...

In this greatest and least area game worksheet, students cut out the cards, draw a card and record the measurement in the length or width column of a graph. When all columns have been filled, they calculate the areas to find the winner...

There are four irrational numbers that participants need to graph. Pi(π), -(½ x π), and √17 are easy to approximate with common rational numbers. On the other hand, the commentary describing the irrational number 2√2 is not...

Learners, after reading an explanation from a NASA Web-based textbook, demonstrate their ability to use, graph (using a graphing calculator), and interpret a text equation.

High schoolers explore a variety of ways of solving quadratic equations. Students choose from graphing, factoring, finding square roots, completing the square and using the Quadratic formula. They ponder in the end on polynomial equations.

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Students study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Students also graph the data they collect and...

Fifth graders find the area of rice farms. For this area lesson, 5th graders draw shapes and grid them to find the area. They compare different rice fields to see which one takes up more space and has the larger area. 

Clarify the Common Core standards for your eighth grade mathematicians with this series of classroom displays. By rewriting each standard as an achievable "I can" statement, these posters give students clear goals to work toward...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Students map and describe small area of the schoolyard and discuss habitats.

Uncover the relationship between factoring quadratics and higher degree polynomials. Learners develop their factoring skills through repetition. A comprehensive lesson begins with quadratics and shows how to use the same patterns to...

High schoolers are able to calculate the population density of a country, and calculate the population density of large cities in that country. They are able to create an appropriate graph to represent their data for that country.

In this pollution worksheet, students collect particles using a pollution detector and then observe their results under the microscope.  They calculate the average number of particles collected in three different locations. They...

Pupils practice a variety of strategies with varying numbers of tiles to form shapes and then find the minimum and maximum perimeter for each one. Each group is assigned a different area to build either with square tiles or a geoboard....

Learners complete the square and identify different parts of a quadratic equation. In this algebra lesson, pupils graph conics using the TI calculator. They rewrite equations by completing the square.
