Numbers and Operations

Have your class read and write large numbers, factor, and solve decimal and fraction problems with this worksheet. For this activity, pupils complete 5 math problems. This worksheet could be used as a practice activity, a pre-assessment,...

There's nothing negative about this mini-unit on integers! Engaging young mathematicians in a series of hands-on activities and collaborative learning opportunities, this resource offers an excellent way to introduce your class to...

In this algebra worksheet, students add, subtract and multiply using complex numbers. They apply the correct property of i as they solve. There are ten questions with an answer key.

Young mathematicians solve 12 equations, determine operations performed and solve 2 test prep questions. Houghton Mifflin text is referenced.

Your learners use many different number representations like positive and negative integers, exponents, radicals, and combinations of operations as they learn and strengthen their use of the order of operations. Thoughtfully organized to...

It's the classic please excuse my dear aunt sally strategy to remembering the order of operations. Young mathematicians practice to develop an understanding of the order of operations. Examples and practice problems include absolute...

Demonstrating a "really hairy and beastly problem," Sal again shows the power and importance of solving an equation according the order of operations. Additionally, he guides viewers through a step in the equation when there are multiple...

First demonstrating the improper ways of solving an equation (left-to-right, multiplication first), Sal shows viewers how the answer of an equation can be drastically incorrect by neglecting to use the order of operations. He uses...

Before Sal can divide a mixed number, he has to rewrite it as an improper fraction. He explains that dividing a fraction is the same as multiplying it by its reciprocal and that you can "cancel out" numbers to make multiplying easier.

Deepen the number sense of your math class with a short presentation on writing equations. Using the relationship between numbers, young mathematicians learn how to determine the missing operator in an equation. A number of opportunities...
