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...

Multiplication in polar form is nice and neat—that is not the case for coordinate representation. Multiplication by a complex number results in a dilation and a rotation in the plane. The formulas to show the dilation and rotation are...

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Look no further for a Valentine's Day-themed packet intended for math and literacy centers. Learners practice writing, reading, and representing numbers in a variety of ways, including skip counting by 2s, 5s, and 10s to 100. The pink...

How many tens and ones are in the number 67? This is exactly the type of question learners are required to answer. They write the numbers in written form, expanded form, and then identify the amount of tens and ones in a given number.

Learning math is so much more fun when it involves playing games. Following the rules of the classic game Memory, young mathematicians flip over two cards at a time as they look for numbers whose sum or difference is equal to the value...

Study Islamic achievement in mathematics by exploring the six standard forms of equations. High schoolers will review the six forms of equations of Al-Khwarizmi. They solve equations using different forms. Links and resources are...

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

Complex doesn't have to mean harder! Learners experiment with online software to determine the quadratic equations with complex solutions. They use the quadratic formula to solve equations with both real and complex solutions.

From exponents to slope-intercept form, an array of extra practice exercises will reinforce necessary skills for your middle and high schoolers. The worksheets include practice with order of operations, graphing equations, scientific...

In this algebra learning exercise, students solve exponential and problems using exponential properties. There are 17 questions, with an answer key.

Find out what's so standard about standard form. Scholars learn to write multiplication expressions with variables in the 10th lesson plan in a series of 36. They use different symbols for multiplication and translate between standard...

How do you write a number in scientific notation? The handout and video provide an explanation on how to convert from standard form into scientific notation and vice versa. The resource also contains a short discussion about choosing...

Place value to the millions is the focus of this math lesson plan. Third and fourth graders investigate multiple ways to represent a number. They examine place value while studying factual information about Pablo Picasso. Resources are...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

How do you operate with numbers in scientific notation? The resource provides examples on how to divide and multiply with numbers written in scientific notation. The handout and video also cover the procedure for addition and subtraction...

Understanding how to multiply a whole number by a fraction is the key concept. Young mathematicians create a visual model of this real-world example and find the solution. Extensions are possible for making this an even richer activity....

Students explore number sense by creating a math presentation in class. In this parts of a whole lesson, students define and discuss the relationship between fractions, decimals and percentages before completing a problem worksheet in...

What was the relationship like between George and Martha Washington? To protect their privacy, Martha Washington destroyed all her husband’s letters after his death so historians have little evidence of their lives together. Two letters...

Learners participate in hands-on activities using a hundreds chart and counting toes and fingers. They discover the patterns that are created when counting by ten. After a lecture/demo, students practice by using a worksheet embedded in...

Capitalism, socialism, communism ... these may seem like a whole bunch of isms to your scholars. High schoolers won't  confuse them after completing an informative resource. Your class masters how to use primary sources to...

Third graders compare numbers. In this math activity students compare ones, tens, and hundreds. They also order numbers from least to greatest and from greatest to least.

Elementary learners discover counting through a counting chart. In this math lesson, students identify numbers 1-100. They then point or recite their counting numbers.

Students study the art forms of the Gilded Age. In this integrated arts lesson, students research the art, music, dance, and drama of the historical era and then create their own personal projects that exemplify the time period.
