Help the class visualize operations with complex numbers with a lesson that formally introduces complex numbers and reviews the visualization of complex numbers on the complex plane. The fifth installment of a 32-part series reviews...

Do you want your budding mathematicians to be able to explain 'why' and not just 'do'? This lesson encourages an understanding of the process of elimination. Pupils are expected to understand how and why the elimination method is a valid...

Define the terms domain, range, function, vertical limit test, and linear function notation with your class. They can then, graph several equations applying the vertical line test to determine which are and which are not functions, write...

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

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...

Be prepared the next time you're in need of a substitute with a daily plan equipped with an assortment of activities covering subjects math, reading, word work, writing, and science. 

Students review how to graph parabolas. They practice graphing two different parabolas using the vertex and table method. They solve problems related to graphing circles, determining the radius and the center.

Graphing systems of linear inequalities is the focus of this worksheet. Problems range from checking solutions of inequalities, graphing systems of two inequalities, and graphing systems of three inequalities. Graphing horizontal lines,...

For this real-world example, algebra learners start to get a sense of how to represent the relationship between two variables in different ways. They start by looking at a partial table of values that define a linear relationship. They...

According to the resource graph, which costs more: peaches or plums? Algebra learners compare two proportional relationships and then throw in a banana. Leaving out the scale helps students become intuitive about graphing. 

Turn your algebra learners into meteorologists. Students are given three graphs that contain information about the weather in Santa Rosa, California during the month of February, 2012. Graph one shows temperatures, graph two displays the...

Here is a task that gives the graph of the solutions of a system of linear inequalities and asks learners to analyze and write the algebraic form of the systems. By turning the problem around, learners make the connections between...

Making a clear connection to algebra concepts helps learners understand the definition of a derivative. The lesson begins with looking at limits of simple linear and rational functions, and leads to the definition of the...

Each form of a linear equation has its purpose — pupils just have to find it. Building on the previous lesson in the series, learners examine point-slope and standard form. Using point-slope form, pupils write the equation of a...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Young mathematicians look for patterns in inverse functions as they relate to the original functions. The comprehensive lesson emphasizes vocabulary throughout as well as algebraic and graphical characteristics of the inverse functions.

First graders examine the relationship between numbers and number families. They listen to the poem "Kangaroo and Toad" by Shel Silverstein and create a list of the largest animals they can think of. Students then order the animals...

In this more or less worksheet, students look at each pair of numbers and then color the number that is larger than the other green. Students repeat the process for the second set of numbers, but color the number that is less yellow.

In this more or less instructional activity, students look at each pair of numbers and color the numbers that are more green. Students color the second set of numbers that are less yellow.

Students make weather predictions and observations, research the cost of snowboarding equipment, and use their math skills to plot the course of a Giant Slalom Snowboarding event.

First graders use patterns in order to identify and recognize even and odd numbers.

For this place value worksheet, students in pairs shuffle a set of place value cards and then lay them out face down on a table. Students then draw a card and place it under one of their place value cards.

Second graders have an opportunity to work in pairs as they search for the missing addend to complete a mathematical sentence. They identify and demonstrate the ability to change the order of the addends and still produce the same sum....

In this congruent triangles worksheet, 10th graders solve 5 various types of geometry problems related to triangles. First, they draw and label triangles, indicating the additional pairs of corresponding parts that would have to be...
