Fifth graders investigate data from maps to solve problems. In this data instructional activity, 5th graders study maps and collect data from each map. Students present their data in a variety of ways and calculate the mode, mean,...

Students investigate place value in base ten. In this number sense lesson, students participate in an online lesson at www.shodor.org/interactivate/activities/NumberBaseClocks and demonstrate how to convert numbers from base ten to other...

Learners investigate poverty using graphs. In this algebra lesson, students collect data on the effects of poverty and use different rules to analyze the data. They graph and use the trapezoid rule to interpret the data.

In this assessment task, learners determine whether a crown with given information is composed of pure gold. The task expects algebraic and numerical solution methods, so unlike Archimedes, no bathtub is necessary.

Learners investigate the effects of low and high temperatures on potato products. For this potato products lesson plan, students demonstrate the effects of storage conditions on Irish potatoes. They investigate the effects of frying,...

Students study operations with real numbers using mental computation or paper-and-pencil calculations. They judge the reasonableness of numerical computations and their results. They set up and solve proportions for direct and inverse...

Students investigate Mayan Numbers. In this algebra lesson, students compare our number system to the number system of the Mayans. They identify base 10 and base 20 numbers including zero in the Mayan symbols. They solve a Mayan problem.

Students identify Roman numerals and the history associated with them.  In this historical number lesson, students investigate charts and photographs to discover the history of Roman numerals.  Students bring a Roman numeral...

Students explore game theory.  In this secondary mathematics lesson, students investigate the playing of a game called Hog which involves rolling dice.  Students explore many different scenarios as they consider the best...

Eighth graders investigate the order of numbers and how they are located on the number line. They also review the symbols used to compare quantities in order to decipher simple expressions and graph them on the numberline.

If you're not right-handed, are you wrong-handed? Young statisticians calculate the percentage of left-handed people using a given data set in the assessment task. They plot data on a scatter plot and consider how the line of best fit...

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...

Your favorite sports team is ranked #1. How do the powers that be determine this rating? Learn how ratings are mathematically computed using probability concepts, from the Elo Rating System for chess to the Rating Percentage Index for...

Don't be a square! Help your budding mathematicians discover patterns within squares. Scholars create squares on geoboards and identify patterns in the number of nails, both nails on the edge of the squares and nails within the squares....

Third graders examine simple machines. In this simple machines lesson, 3rd graders observe simple machines at work in a video, then experiment with creating their own simple machines to move objects.  

Students use a simple machine (a lever) to launch a plastic frog. students determine who is able to make their frog "jump" the farthest and graph the results.

Students identify properties of parabolas. In this algebra instructional activity, students factor quadratic equations and identify the properties of parabolas. They find the roots, vertex and intercepts of a parabola.

Students investigate levers. In this simple machine lesson, students study levers and  the mechanical advantage of using levers. They will collect data and illustrate their systems for eight different tests.

Young scholars identify the nth term in a sequence. In this algebra lesson, students generate sequences given the formula for each sequence. They find the formula given the sequence.

Learners investigate woodbugs. In this scientific investigation instructional activity, students explore the steps scientists take when conducting an investigation using live specimens. Learners explore habitat preferences for woodbugs...

Young scholars study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Fourth graders interpret the weather data they gathered in Investigation 6. They take an average of each component in each season. They compare the same components of each season and write the differences they see between the seasons.

Students independently investigate the Pythagorean Theorem. They are given a set of triangles that involve whole number Pythagorean Triples. The main focus of the lesson is exploration rather than discovering the Pythagorean Theorem.
