Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Students pretend they are about to buy their first new car. They must do all the calculations necessary to estimate the cost of purchasing the car. They see that the math they learn in school really does have real-life applications.

Second graders investigate the addition of whole numbers. They mentally perform calculations involving addition and subtraction. They make sensible estimates and check the reasonableness of answers.

Learners use an Internet tool, "The Take-Away Bar" to solve subtraction problems by breaking them into parts. They write and solve comparison problems. Students make sensible estimates and check the reasonableness of answers. They use...

Learners experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

High schoolers make sensible estimates and check for reasonable results. They also solve problems with positive and negative integers using practical activities or models as needed.

Young scholars explore the concept of Venn Diagrams through word problems. In this Venn Diagram lesson plan, students solve word problems about groups of people using Venn Diagrams. Young scholars use survey results about MySpace and...

Students calculate the time difference between Beijing, China and their local community. They discuss how time difference affects intercultural communication.

Get your class out in the environment for hands on math activities. For this wetlands lesson, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They then make...

Students practice multiplying decimals and/or mixed numbers, explore the effects of multiplying decimals and mixed numbers, and practice predicting the effects of multiplying a number by a decimal or mixed number.

Students investigate money. In this consumer math lesson, students use coins, identify their value, then group them in various ways to equal a dollar.

Constructing decimals correctly is a crucial concept for elementary learners to grasp. Here, have the young mathematicians in your class explore standard and expanded form while comparing decimal values. This unit is taught while...

Students build and program a car to drive a specific challenge distance.They must at the end of the lesson, have the car that stops the closest to a challenge distance.

High schoolers discuss what expected value is, they are introduced to the concept of varyting payoffs. Students use a computer simulation of a "real world" example where expected value is used.

Sixth graders explore a relevant application of ratios and proportions. They apply this concept through guided practice and interactive feedback.

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.

Students collect and record data. In this early data analysis lesson, students gather data about their partners face. As a class, the students use tally marks and pictographs to record the data and answer question about the information...

Second graders explore how to incorporate a new type of technology, the cash register and/or a calculator, as a motivational tool for solving real life problems. They practice estimating money and counting back change from $20.00.

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students explore the global grid system. In this globe lesson, students identify latitude and longitude lines and how these can tell the coordinates of any place. They use the Internet to find the exact coordinates for their town. 

Students convert metric units of length, specifically meters, centimeters, and millimeters. In this lesson of converting measurements, students participate in various games which require them to put the measurements in order or convert...

Students solve the handshake problem and investigate triangular numbers. In this geometry lesson, students investigate Blotto games as they apply concepts of triangles and geometric theorems.

Middle schoolers explore expected value, are introduced to the concept of varying payoffs, and have used a computer simulation of a "real world" example where expected value is used

Young scholars demonstrate and describe the effect of multiplying or dividing by a fraction less than or greater than one. They create and explain a variety of equivalent ratios that represent a given situation. Students draw a picture...
