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...

Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

Youngsters discover the difference between estimating and guessing. They estimate how many items are contained in a jar as they read a story. After the story, pupils discover the differences between estimating and guessing and create a...

Young leearners identify subsets of the real number system and play a number game to identify natural numbers, whole numbers, integers, rational and irrational numbers.

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

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....

Third graders investigate two mathematic scenarios and determine which is correct. They compare adding columns and places (such as the tens place, hundreds place, and so on) and familiarize themselves with how to add larger numbers.

Help your class make sense of quantities and their relationships. Given is the product of two numbers. It is up to your number crunchers to think about the quantitative relationship when the product is one-tenth or ten times the product...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

Why do all sizes of pictures not show the same thing? Class members analyze aspect ratios of various sizes of photos. They determine which sizes have equivalent ratios and figure out why some pictures need to be cropped to fit...

Solving a murder is like isolating a variable. Using a video on a murder mystery, the narrator introduces the idea of solving a literal equation for one variable. After solving several equations, the class comes up with a set of...

Patterns, patterns, everywhere! Young scholars examine the multiplication table to identify patterns. Their exploration leads to an understanding of the difference of squares and sum of cubes by the completion of the algebra project.

The addition and subtraction of decimals is a relatively simple process. The most important thing to remember is to have all of the decimal points lined up. This presentation gives that strategy, plus some others to use when performing...

Using a varity of strategies, young mathematicians solve multistep word problems. They play a logic game as a whole group, and then work with a partner on a computer to complete a worksheet that requires a variety of problem solving...

Let the resource stretch the minds of your young scientists with a lesson about tensile strength and stiffness of materials. Groups consider how easily materials stretch and relate this property to engineering design.

Fifth graders practice using money in everyday situations. They use their addition and subtraction skills as they work in cooperative groups to solve problems involving decimals.

Sixth graders listen to Demi's, On Grain of Rice: A Mathematical Folktale. They use the problem solving strategy of finding a pattern to determine the number of rice Rani will receive after 30 days. They create a spreadsheet which...

Learners complete subtraction problems where they use goldfish crackers as their manipulatives in the problem. In this subtraction lesson plan, students use words and pictures to also show their problems.

Mix it up by using an intriguing resource that teaches young metallurgists that alloys are a metal mixture. They learn about the advantages of using alloys over pure metals and investigate titanium alloys as an example to finish the...

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...
