Using a concept attainment approach, learners identify surface area and volume by sorting examples (photos) that depict each concept (positive)  from those that don't (negative). Then as a class, they develop definitions of each...

Upper elementary and middle schoolers work with the concept of probability. They are introduced to the concept of chaos. Learners graph and analyze using a line plot, work with mean, and are introduced to the concept of variance.

Students use ratios and proportions to represent quantitative relationships as they investigate the concept of how percentages are used by designers. Students decorate the same room using three different percentages of colors.

Learners understand the definitions for perimeter and circumference and know the difference. They then go over sample problems as a class. Students use drill and practice skills to complete activity pages.

Sixth and seventh graders investigate the concept of negative numbers. The instructional activity begins with a review of positive numbers and progresses to the various operations with negative numbers. The instructional activity...

Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Students work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

Students collect data and visually represent it. They conduct a survey of favorite movies. Using a spreadsheet, students organize the data and create bar and circle graphs. Students answer statistical questions regarding the data.

Learners are introduced to the concept of radicals and how to use them in various situations. They review rational and irrational numbers while simplifying different number sentences. They also practice factoring perfect squares.

Students explore the concept of central tendencies. In this central tendencies lesson, students sort M&M's or Skittles based on color. Students graph their results. Students find the mean, median, and mode of their data.

Middle and high schoolers explore the concept of scale drawings. They discuss what a scale is and that scales provide a ratio. Pupils construct a scale drawing of their classroom using graph paper.

Middle schoolers apply properties of probability to the real world. In this probability instructional activity, learners simulate the construction of empirical distribution. They collect and analyze data using central tendencies.

Ready to introduce your class to the coordinate plane? This website includes a detailed lesson plan that includes two interactive games to help learners practice graphing ordered pairs. The scripted discussion is a little cheesy and a...

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

Written as an accompaniment to a field trip to the Out of Africa Wildlife Park in Arizona, this is an interdisciplinary, themed lesson on lions. Even if you cannot take your upper-elementary kids to this attraction, there are a few...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...

Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a...

Students practice using measurements and bar graphs to solve a running problem in this active Math lesson for various age levels. The lesson meets state standards in Mathematics and requires the use of "math journals" for final...

Students draw a ship to scale, and calculate the real life size. They show that measurements on the drawingsare annotated with the distances reported in inches (fractions and decimals), and their real-world equivalents

Students make observations of effigy mounds and record them in a notebook. In groups, they must determine the scale of measurement and create their own grid to scale part of the Effigy Mounds National Monument. They also practice using...

Learners participate in guessing their partners' hidden Lego pieces from their verbal clues. They work in partners to accomplish their goals. They are meeting a variety of math standards by completing this lesson.

Students discuss the appropriateness of using a specific tool to measure and define an object. After measuring the area of their classroom and the objects in it with the appropriate tools, they create a floor plan that makes the most...

Learners convert English to metric units. In this math lesson, students give examples of measurements they encounter in their daily lives. The share their answers in class.
