Paper folding, flu spreading in a school, bacteria growth, and continuously compounded interest all provide excellent models to study exponential functions. This is a comprehensive resource that looks at many different aspects of...

Scientist work with negative integer exponents all the time. Here, participants will learn how to relate negative exponents to time and to generate equivalent numerical expressions. Learners will apply the properties of integer exponents...

The speed of a dragonfly brings math into the real world as your learners collaboratively see the value in calculating unit rates in direct proportion problems. This six-phase activity encourages you, as the teacher, to only ask...

Here is another opportunity for math students to apply reasoning to solve real-world problems with ratios. The ratio of the number of votes for two candidates is provided. Your class is asked to use this ratio and information given about...

An interesting example of a discrete function and how it is applies to the real world. This could easily make a good collaborative lesson with an environmental science class. Practice reading a table and drawing a scatter plot make up...

Take a walk through time, 1852 to 2005, following the mathematical history, development, and solution of the Four-Color Theorem. Learners take on the role of cartographers to study a United States map that is to be...

How many boys are in the class? Here is an introductory exercise describing ratios. The commentary shows different ways learners can approach the problem, using a tape diagram of boys to girls and using a table. The activity includes...

The learner must use the given constant speed to find the unit rate. A table is made in order to relate the speed to the time and the distance. From the table, learners are able to see the unit rate in miles per minute and miles per...

Your learners explore growing patterns by describing, extending, creating, and evaluating practical pattern problems in this three-day collaborative unit. Beginning with concrete patterns and function tables to extend and...

An inventive lesson shows learners how to collect, organize, and present mathematical data. They access websites which lead them through a variety of ways to engage in data collection. They get to design and create graphs, and present...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

This comprehensive resource applies simultaneous equations to a real-life problem. Though the commentary starts with a graph, some home consumers may choose to begin with a table. A graph does aid learners to visualize the shift of one...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

The votes are in and your mathematicians are going to calculate how many votes each candidate received. Three different solution choices are given, depending on which method is taught. Have your learners set up a table, compute parts, or...

An addition table supports third graders as they learn strategies to improve their math fluency. When finding sums greater than ten, students are taught how to first make a ten and then add on the rest. A similar method is also...

Put math into action with the real-life scenario of a bake sale. The participants at this bake sale are ready to divide their fresh-baked cookies into bags. It is up to your number crunchers to help decide how many cookies should go in...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Using the Hudson River as the focus, learners discuss the difference between salt water and fresh water environments, analyze maps and graphs, and complete addition and subtraction problems. This activity comes with a wealth of...

Everyone loves math when it includes food! This lesson tries to take the notion of combining like terms in algebra and comparing it to sorting apples and oranges. It takes a step-by-step approach to helping students understand this...

Rivers aren't just a place for animals to live, they also provide industrial transportation. The class will examine the Hudson River on a map, discuss all the commercial vessels that use the River to transport materials, then complete a...

Using boats along in the Port of Albany as the focus, learners practice adding single-digit numbers and interpreting data. This lesson comes with the worksheets, resource links, and other materials to make it a worthwhile experience.

Just about every public building that your learners are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

An outstanding lesson on music awaits your young composers! They learn about patterns found in music, the different sections of an orchestra, and see the differences between musicians and a composer. Excellent streamed videos and good...

Using a game format, learners review what they know about theoretical probability. As they roll tetrahedron dice, they record their results as odd or even. Afterwards, they discuss their findings.
