Understanding the concept of equality is fundamental to the success of young mathematicians. To explore this basic idea, children compare the dots arranged in pairs of rectangles in order to determine whether or not they contain an equal...

It's said that opposites attract, but what about opposites of opposites? Individuals learn about the opposite of opposites using number lines. They complete a group activity in which members determine the opposite of opposites of...

Kurt Vonnegut's short story "Harrison Bergeron" engages adolescents with its theme about the dangers of complete societal equality. Learners complete a graphic organizer to track literary elements in the story, as well as an inference...

Scholars learn to order rational numbers in the seventh lesson in a series of 21. Reasoning about numbers on a number line allows for this ordering.

Individuals learn how to plot rational numbers on the number line in the sixth lesson of a 21-part module. They identify appropriate units and determine opposites of rational numbers.

Integers can be challenging, but this presentation makes teaching integers a whole lot easier! Comprehensive information, a song, chant, and pop quizzes provide an in-depth look into what integers are, and how to add, subtract, and graph...

Division can be seen in two ways; as splitting a whole into a certain number of pieces, or splitting it into pieces of a certain size. Help your class reach this understanding with these two simple word problems. Encourage the use of...

Understanding when to divide by two or one-half can be confusing. Here is an activity that gives four different scenarios. It is up to your number crunchers to decide if they divide by two or one-half. The easiest way to approach the...

Increase understanding of the algebraic properties and their importance. Scholars justify their steps as they simplify expressions and solve equations. They formalize their work as two-column proof.

The Internet is known as the information superhighway, but sometimes it's hard to know when to hit the brakes on unreliable sources. Using a well-rounded lesson plan, pupils read and summarize articles about the gender pay gap and...

Deepen the fractional number sense of young learners with this introductory lesson on equivalent fractions. After completing a short warm-up activity, children go on to work in pairs using fraction circles to complete a table of...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

What's in a name? Pupils create a data set based on the number of letters in classmates' names. Each group then uses the data to create a visual representation, such as a histogram, circle graph, or stem-and-leaf plot.

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

Explore properties of addition as they relate to matrices. Using graphical representations of vector matrices, scholars test the commutative and associative properties of addition. They determine if the properties are consistent for...

Challenge the addition skills of young learners with this open-ended math problem. The task is simple, get from start to finish by connecting a series of three numbers. The trick is that the sum of the numbers must be less than...

Statistics are more than just numbers—they can give you important information about a set of data. Pupils learn how to find the mean, median, and mode of a data set. They also find the next score to reach a desired mean.

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

What are fractions? Find out using a reference page and video that goes in depth on how to make fractions equivalent, write fractions in simplest form, convert improper fractions into mixed numbers, and vice versa. Following...

What does it mean to solve an equation? The resource revisits the concept of making a linear equation true. Classmates use algebraic methods to transform sides of equations to expressions with fewer terms. They use substitution to...

Practice your fourth grade math concepts with a series of flash cards. Covering topics such as place value, decimals, fractions, measurement, and many more, the flash cards can help learners of any level with their comprehension. The...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Visual models are a great tool for demonstrating the concept of equivalent fractions. Given two pictures, young mathematicians first identify each fraction and then write an explanation for why they are equivalent. Use as a guided...
