Numbers and Operations Teacher Resources

Break down addition and subtraction into short sentences using this brief worksheet. Each question prompts scholars to make a number by doing three math operations. For the first, they make 10 by adding three, adding five, and...

These equations are missing numbers, and scholars must process multiple operations to complete them. There are addition, multiplication, and division problems here, each missing an addend, divisor, or factor. After completing 24 of these...

When did math become so relevant? Scholars choose from four operations to solve five word problems dealing with money and measurements. They show their work in a designated space, and must include units in their answers. Learners work...

Can Dan make a conjecture about dividing fractions with the same denominators? That is what your scholars are to determine. They must show that if the statement is true, they understand how the quantities were determined, and how...

Teach class members to work with rational expressions using their knowledge of fractions. The lesson plan starts with a warm-up of rational expressions at four different levels of complexity. The different levels continue throughout...

There are three parts to this lesson on integers. In the first, learners explore positive and negative numbers on an actual painter's tape number line and by playing a "Hot Seat" game. In part two, they view a BrainPop video and work...

Expand your knowledge of exponents with an activity that promotes critical thinking and comparison skills. Middle and high schoolers compare numbers written in expanded and exponential form and explain their strategies for solving...

Is your class beginning a project? Here's a template that shows researchers how to use the features of Google Scholar. Directions for how to use Advanced Search, Operators, and Bibliography Manager, as well as how to locate affiliated...

To present a potential inconsistency in the price-to-earnings ratio, Sal creates a scenario based on two entrepreneurs who each purchase a pizzeria with identical assets. The first pays the entire cost outright, while the second pays 10%...

For this sequencing worksheet, learners make a number sequence chart by following the given rule, continue number sequences through seven additional numbers, and continue patterns. Students solve five multiple answer problems.

Go on an electronic field trip. Discover Spanish-speaking countries through Internet exploration. Young scholars participate in a whole group discussion to general knowledge about the location, cultural background, independence and...

This unit on integers includes a pre-test, a post-test, four spreadsheets, and links to an interactive web-site to support the learning of integer operations. Access to computers and the Internet are imperative to this unit. The lessons...

Here is a basic video on scientific notation. The presenter defines scientific notation for very large and very small numbers. Then he shows how to convert numbers to scientific notation, and how to do the reverse by converting from...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Show your classes the magic of numbers. Using a number trick, learners practice writing algebraic expressions. They then use their expression to perform the trick. Their exploration should help them understand the magic behind the trick.

Work with fractional cookies. The three-part assessment task checks the pupils' ability to find the product of fractions and whole numbers, mixed numbers, or fractions. Learners determine the amount of ingredients needed and how many of...

Two online lessons, one in math and one in language arts, are here for you. In them, learners play online games which reinforce important skills in literacy and numeracy. The thing I like about both of these lessons is that they get the...

How can two numbers be multiplied to get a product of one? Why is this even important? One reason this is an important skill has to do with getting rid of denominators. So learn about multiplicative inverses in this video.

How much do you know about exponents? The pre-test covers the concepts of integer exponents with both numerical and algebraic one-variable expressions. The test is also over representing numbers in scientific notation, operating with...

Eric and Leila's video game scores are the inspiration for writing equations with parenthesis. The numbers are purposefully large to deter the class from calculating them: rather this activity meets the standard that asks 5th graders to...

Students create a group wall drawing that demonstrate the contributions that each part makes to the whole.

Abracadabra! Letters can be used in math to represent numbers with the operations of addition, subtraction, multiplication, and division to solve problems! Math magicians will participate in an activity that uses a calculator and a bag...

These four lesson plans build algebra skills for working with numbers in exponential form and for examining triangles. Be aware that in the text, scientific notation is referred to as index notation and the laws of exponents as the laws...

This presentation takes the topic of scientific notation past the basics to look at some more complicated problems of simplifying numbers in scientific notation. Specifically, they cover multiplying a number in scientific notation by a...
