Explore the connection between fractions and rational expressions. Young scholars manipulate fractions with unlike denominators to find a total. Challenge questions allow them to check their work to ensure they are correct.

Working in groups, pupils plot three points on the coordinate plane representing three different parabolic paths. Using a calculator, they determine the quadratic regression equation for their models. Each team then figures out the...

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Establish healthy eating habits with a instructional activity focused around MyPlate's food recommendations and the importance of eating fruits and vegetables. Through class discussion and worksheet completion, scholars discuss the best...

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

How much does your class know about Puerto RIco? How much can they learn from the back of a 2009 quarter? Use the coin, part of a series of quarters that depict US territories, to teach learners about the geography, culture, and history...

Young learners will view a math adventures video and practice math concepts.  Afterwards they will navigate through Internet sites to participate in teacher selected math adventures. This guide walks you through integrating...

Mathematicians use a CBR 2™ motion detector to determine their speed or velocity going down a playground slide. They also experiment with different ways to increase their speed going down the slide. Finally, students complete the Student...

Young mathematicians explore the maximun area for patio with the added complexity of finding the mimimum cost for construction. First, they maximize the area of a yard given a limited amount of fence and  plot width v. area on a...

Place value and the reading and writing of large numbers, are the focus of this math PowerPoint. Students are taught that place values can be bunched up into "periods," which consist of the ones, thousands, millions, billions, and...

Your mission, if you decide to accept it, is math skills practice. In this app, Mission Impossible meets basic number operation skills, and your students are the secret agents. 

Develop an understanding of positive and negative numbers using football. Pupils create a football field and game pieces. The teacher gives plays and the pupils move pieces to see who wins the game.

Uncover the properties of translations through this exploratory lesson. Learners apply vectors to describe and verify transformations in the second installment of a series of 18. It provides multiple opportunities to practice this...

Help your pupils find a pattern of direct variation. Young scholars use input-output pairs to find a constant of variation and then write the equation. As they build their equations, the interactive lesson provides feedback.

Join together to investigate truss joints. Scholars learn how to analyze forces at truss joints to determine the strength of truss bridges. They apply the "method of joints" in calculating the tension and compression forces at each joint...

What a great way to have pupils apply classroom learning to real-world skills! They complete problems involving the addition and subtraction of decimals related to banking-type questions, and then use a spreadsheet to display their results.

There are four activities in this extensive lesson covering the identity matrix and scaling, the linear representation of translations, the linear representation of rotations, and reflections. In small groups, they use the Cabri II...

Decimal place value is the topic of a Battleship themed-interactive. Scholars answer five questions—multiple-choice and true or false—while referencing a grid that acts as the board game. The practice concludes with a discussion...

Using the NASA website, class members try to determine if changes could be detected in cloud cover, temperature, and/or radiation measurements due to the lack of contrails that resulted from the halt in air traffic after the attacks...

Using Google SketchUp, learners draw a model of their bedroom. They begin by measuring the dimensions of their bedroom, inputting this information into the software program, and calculating perimeter and area. This is an interesting and...

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

Learn more about genetic modification, organic farming, and the role of biotechnology in agriculture by watching a documentary that shows how newly gained knowledge can be applied to specific situations involving farmers and the choices...

Three activities make up an introductory lesson designed to create a strong foundation in comparing fractions to decimals and exploring and building decimal models. Pupils brainstorm and complete a Venn diagram to show how decimals and...

Some lessons feature videos, some interactive practice problems, and some have notes and activities. This comprehensive look at factoring and solving polynomial equations using the zero product principle has all of this and more. Though...
