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 activity, young scholars 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.
Young scholars 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.
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.
Students 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.
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.
Students solve problems with complex numbers. In this algebra lesson plan, students use addition, subtraction, multiplication and division of complex numbers.
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.
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.
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 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.
Students 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.
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. 
Sometimes the simplest ideas can be the most challenging to solve! For 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?  
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.
This is a cute instructional activity 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 instructional activity is that it can be personalized to fit your class.
Students investigate place value in base ten. In this number sense lesson, students participate in an online lesson at and demonstrate how to convert numbers from base ten to other base values.
Sixth graders will practice dealing with whole numbers using the order of operations and performing calculations using the four basic operations. The lesson also includes practical investigation into the use of rational numbers.
First graders read Imogene's Antlers by David Small the create pipe cleaner antlers. Using these as a tool students combine and create number sentences. They continue to work through the framework of a software program.
Students perform operations with decimals. In this algebra lesson, students analyze data using the mean, median and mode. They use Frayer Model to help them understand how to solve problems with decimals and how to use it in the real world.
Fifth graders play a game that reinforces basic mathematic operations. In this operations lesson, 5th graders listen to the story, The best of Times by Greg Tang then practice using addition, subtraction, division, and multiplication with whole numbers.
