Students identify variables that affect the system, and specify which variables are independent and which are dependent.

Drawing circles isn't the only thing compasses are good for. In this first installment of a 36-part series, high schoolers learn how to draw equilateral triangles by investigating real-world situations, such as finding the location of a...

What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Groups sort through NASA data provided in a graphic to create a graph using uniform units and intervals. Individuals then make connections to the increasing, decreasing, and constant intervals of the graph and relate these...

Does a linear or exponential model fit the data better? Guide your class through an exploration to answer this question. Pupils create an exponential and linear model for a data set and draw conclusions, based on predictions and the...

Math language? Set notation is used in mathematics to communicate a process and that the same process can be represented as computer code. The concept to the loop in computer code models the approach pupils take when creating a solution...

What does English have to do with math? Teach your class the "grammar" of a number sentence. Sentences with correct grammar can be false! Understanding of a number sentence leads to a comparison with equations.

How many ways can you represent solutions to an equation? Guide your class through the process of solving equations and representing solutions. Solutions are described in words, as a solution set, and graphed on a number line....

Teach solving equations through an exploration of properties. Before pupils solve equations they manipulate them to produce equivalent equations. The activity switches the focus from finding a solution to applying properties correctly.

Do properties of equations hold true for inequalities? Teach solving inequalities through the theme of properties. Your class discovers that the multiplication property of equality doesn't hold true for inequalities when multiplying by a...

English and math have more in common than you think. Make a connection between a compound sentence and a compound inequality with an activity that teaches learners the difference between an "and" and "or" inequality through solutions...

Be ready mathematicians of every level. This lesson leads to the discovery of the zero product property and provides challenges for early finishers along the way. At conclusion, pupils understand the process of using the zero product...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Ratios may not be created equal, but they are equivalent. Pupils learn the theorem relating equivalent ratios and equal values in the eighth segment in a series of 29. Classmates use the theorem to determine whether ratios within...

Even or not, here I come. Groups investigate the parity of products and sums of whole numbers in the 17th lesson in a series of 21. Using dots to represent numbers, they develop a pattern for the products of two even numbers; two odd...

Where in the world is the equator? Explore a world map with your class, coloring in oceans, continents, and rainforests while locating the three major lines of latitude: the equator, Tropic of Cancer, and Tropic of Capricorn. Discuss how...

Scholars determine statements as fact or opinion in a practice page consisting of two reading passages followed by multiple choice and short answer questions. Fact and opinion passages detail information about Chicago and Ethiopia. 

Discover how trend lines can be useful in understanding relationships between variables with a lesson that covers how to informally fit a trend line to model a relationship given in a scatter plot. Scholars use the trend line to make...

Gustav Holst's The Planets provide young musicians an opportunity to examine how composers can create a suite: a collection of smaller pieces grouped to explore a single topic. After listening to "Jupiter," they examine "Mars" in...

Guide your readers to explore character traits. As a class, discuss and record the traits of a commonly-known fairy tale character. Then do the same with the main character in the class novel. Finally, have learners use magazines...

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

Students view a teacher demonstration of comet composition. In this comet science lesson, students watch as the teacher combines sand, ammonia, cola, and dry ice to simulate the composition of a comet. They answer discussion questions...

Elementary schoolers identify the three methods of heat transfer: conduction, convection, and radiation. The lesson is mostly lecture-based. When the teacher has finished the presentation, groups of pupils get into teams and they must...

Not really a resource for use in the classroom - this file is a PowerPoint presentation which gives information about Dyspraxia. It is a very interesting presentation because it shares many signs to look for in a person who may be...
