Students explore fact families. In this multiplication lesson, students use a multiplication table to find the answers to several multiplication equations. Students form fact families from each completed equation.

In this determinants worksheet, 9th graders solve 10 different problems that include different matrices. They calculate the determinant of each matrix using the data given for each. Then, students define the 2 X 2 matrix and its...

Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve...

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. 

Don't worry, this resource actually exists. Scholars learn about imaginary numbers and work on problems simplifying square roots of negative numbers. As an extension, they research the history of imaginary 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...

Kids gain a deeper understanding of mathematical symbols, by playing an interactive game using flash cards. They complete an attached Missing Symbols Worksheet, flash card and an assessment are also included.

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....

Matrix multiplication can seem random to pupils. Here's a instructional activity that uses a real-life example situation to reinforce the purpose of matrix multiplication. Learners discover how to multiply matrices and relate the process...

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.

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...

Young scholars explore multiplication concepts.  In this multiplication instructional activity, students define "array" and draw several arrays to represent multiplication number sentences.  Young scholars construct arrays on...

Eleventh graders study how to combine like vector's that are matrices. For this matrix operations worksheet, 11th graders combine matrices linearly and define the matrix-matrix product and its properties. Students also study matrix...

Investigate how public key cryptography works. Scholars continue their study of one-way functions and asymmetric keys and apply this information to public key cryptography. They use an app to explore public key cryptography and its...

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...

The class explores the concept of complex numbers on a website to generate their own Mandelbrot sets. They will practice performing operations with complex numbers and then to get a visual understanding, graph the absolute value of a...

Start with the definition of a determinant and how to evaluate a 2x2 determinant. Apply this skill to solve systems of two equations with two unknowns by using Cramer's rule. These four basic problems would be good for a quick review or...

Students explore math functions by completing a worksheet in class. In this spatial movement lesson, students utilize a four square grid and a penny to practice moving the coin horizontally, vertically and diagonally as instructed....

Students explore statistics by completing a graphing activity. In this data analysis lesson, students define a list of mathematical vocabulary terms before unpacking a box of raisins. Students utilize the raisins to plot data on a line...

Third graders collect data about themselves and use in a line plot. In this analyzing data lesson, 3rd graders collect various sets of information,create a line plot and compare the data.  Students complete a worksheet on their...

Ninth graders factor equations and find prime numbers. In this algebra lesson, 9th graders find the factors and prime factors of a number using multiples and relatively prime numbers.

Learners draw arrays. In this multiplication lesson, students draw arrays, write multiplication sentences for arrays and discuss how changing the order of the factors affects the product.
