Inject fun into your math review! Pupils review basic math operations with decimals as well as addition and subtraction with simple fractions. In this number operations lesson, students work in groups to create a game for the math skill they are given. Students share their ideas, decide on one and create the game. This could be used as a cumulative assessment.
Numbers, Number Sense, and Number Operations
Students define what prime and composite numbers are and how to identify them. Through games, drills, and quizzes, they identify they rules that make prime and composite numbers. Worksheets and forms are included.
Ordering Numbers And Understanding Addition And Subtraction
Learners study the vocabulary of comparing and ordering numbers. They order whole numbers to at least 100, and position them on a number line and 100 square. They find a small difference by counting up from the smaller to the larger number.
The Big Bus Module: Mental Maths
Elementary schoolers practice their mental calculation skills to strengthen all four number operations. They interact with the Big Bus Module to participate in a variety of exercises their multiplication and division skills. Each student masters the ability to quickly and accurately to math problems presented on the screen.
Complex Number Operations
Students solve problems with complex numbers. In this algebra lesson, students use addition, subtraction, multiplication and division of complex numbers.

Your mission, if you decide to accept it, is math skills practice. In this app, Mission Impossible meets basic number operation skills, and your students are the secret agents.
Properties of Operations
Learners consolidate and extend understanding of simple properties of the four arithmetic operations. They use these properties as an aid to easy calculation. They discover and use some more complex properties of addition, subtraction, multiplication and division.

Sometimes the simplest ideas can be the most challenging to solve! In this app, you are given five numbers and a set of operators, and you need to create an expression that when evaluated using the order of operations simplifies as the target number. Sounds easy, doesn't it?
Number and Operations Sense: Whole Numbers
Explore operations with whole numbers, using a calculator to develop understanding of the effect an operation has on the numbers involved. Your class collects data, looks for patterns, and makes conjectures regarding numbers or operations.
Number Lines and Bead Strings
Students solve addition and subtraction problems using strings of beads and number lines. They mentally perform addition and subtraction problems, and write and solve story problems involving whole numbers.
Introduction to Order of Operations
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 several examples to demonstrate the order of operations at work and clarifies the times when the answer to an equation will be the same no matter what the order.
A Human Number Line: Teacher Notes
Twenty-one pieces of tagboard can lead your class to a greater understanding of integers when you use them to form a human number line. After creating this math tool, two strategies for adding and subtracting will have your mathematicians up and manipulating positive and negative numbers. Assessment opportunities include suggestions for graphing equations and inequalities.
Business Basics (Numbers Operations)
Seventh graders solve problems using order of operation. For this algebra lesson, 7th graders compare and contrast rational and irrational numbers. They create a T-chart to help differentiate between the two.
Independent Practice 1: Number Operations
In this number operations worksheet, students write in the missing symbols between the numbers to make the equation correct. For example: 4 __ 3__ 1, and students write in the symbols so it reads: 4 - 3 = 1. There are 20 problems on this worksheet.
Students listen to the problem and think about the first question and the number operation that they would use and explain. They work in pairs and record their solutions so that they can be displayed and shared.
Operation and Symbol Sense
Young scholars write what each of the 4 basic operations mean, provide examples, and solve problems. In this operations lesson plan, students also fill out charts and identify patterns.
Properties of Real Numbers
Students use paper cups and colored chips to observe properties of operations with real numbers. As a class, students brainstorm and use manipulatives to demonstrate associative, commutative, distributive identity and inverse properties. In groups, they write a "properties poem" and create a slide show explaining the properties. Additional multi-sensory projects are listed.
Operations with Complex Numbers
This activity is a great introduction to the operations of complex numbers. Combining their knowledge of algebra and the use of a calculator, your class can discover and apply the rules for adding, subtracting, and multiplying complex numbers.
Understanding Rational Numbers and Proportions
Here is an excellent lesson on fractions, decimals, unit rates, proportions, and problem solving. In it, learners engage in six activities in an "investigation center." The activities are based on a fictitious trip to a bakery, and involve several important concepts of rational numbers and proportions. Outstanding blackline masters are embedded in the plan, which will make it easy to successfully implement the lesson with your class.
Addition of Two and Three Digit Whole Numbers
This is a cute lesson that kids will be able to relate to. They are shown how to trade tens and regroup when adding and subtracting two digit numbers. The nice thing about this lesson is that it can be personalized to fit your class.
