Second graders subtract two-digit numbers. In this mathematics lesson, 2nd graders subtract both with and without regrouping. Students use manipulatives and place value mats to assist in problem solving.

Once your geometers know how to apply the formula V = l w h, they will be ready to take on the fractional volume of a fish tank. Have your number crunchers swap heights so they can see that the fractional volume will not change. 

Teach teenagers to think critically about data. Young data analysts must create two questions that can be answered using a provided data set on Olympic cycling times. Of course, they then have to answer their questions using mathematics.

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Investigate how public key cryptography works. Scholars continue their study of one-way functions and asymmetric keys and apply this information to public key cryptography. They use an app to explore public key cryptography and its...

What makes number pairs perfect? The resource provides five problems regarding perfect pairs of numbers, the definition of which changes in complexity with each task. Solutions require pupils to apply number sense and operations, as well...

Challenge individuals to compete as many tasks as possible. Lower-level tasks have pupils apply costs and rates to solve problems. Upper-level tasks add algebraic reasoning and conditional probability to the tasks.

Your breakfast cereal is a good source of math practice. Young mathematicians apply ratios and percents to analyze the amount of protein and carbohydrates in two brands of cereal. They complete a worksheet to answer several questions on...

Learners apply their understanding of luck to a probability experiment. They play a game of Pass the Pigs to determine the probability of a specific outcome. Using analysis for their data, pupils declare the measures of center, dot...

Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...

Tap into the desire to learn about computer codes. Pupils apply the Tap Code and the Polybius Square to send secret codes using sound. They design a code that tells a robot what movements to make and then test out their code using one of...

Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

High schoolers explore and analyze how the human face is proportioned and explore ways artists use mathematics to make art. They demonstrate the basic face proportions by creating a reference sketch and illustrating visual clues to...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this activity is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions....

Students explain the practical uses of robots. They interpret possible careers in robotics, apply the safety guidelines of robots, and develop a perspective of the use of robots. They empathize with the cultural issues of robots in work...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

This interactive website provides a variety of lesson plans according to which standards you are applying and which textbook you use. Introduce functions to your class by having them construct single operation machines and create...

A bouncing ball serves as more than entertainment when learning to apply quadratic functions to real-world events. This is the second of a two-part lesson, which can also be accessed from the website. The instructions say to measure the...

Students consider the future of endangered species. In this conservation lesson, students view a slide show and use mathematical data to construct a prediction for the survival of an endangered species. This lesson includes, personal...

Sixth graders explore the scientific method by conducting an in class experiment. In this scientific averages lesson, 6th graders discuss the concept of the scientific method, and define the different mathematical averages, mean, median...

Have learners graph complex numbers to gain a visual and mathematical understanding of the distance and the midpoint between two complex numbers. This lesson is short, but to the point, and addresses an important complex number...

Mathematicians show their understanding of a division problem. If a student can apply long division to a pair of numbers and determine a quotient, what other factors and multiples become apparent? The example illustrates a simple...

Get your learners to think outside the box. Learners require a good understanding of ratios and their relationship to fractions to complete the problem. The only quantities given in the problem are the ratio of the number of votes for...
