Inject fun into your math review! Pupils review basic math operations with decimals as well as addition and subtraction with simple fractions. For 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.
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.
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.
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.
In this video, a complex number is defined and graphed on the complex plane. Sal also shows how to add, subtract, and multiply two complex numbers. He starts showing how to divide two complex numbers, but runs out of time and continues in the next video.
Fourth graders examine the relationship between multiplication and division and subtraction and division, and determine which operation is needed to solve various problems. They observe and participate in a teacher-led lecture, and complete various worksheets.
Students solve problems with complex numbers. In this algebra lesson, students use addition, subtraction, multiplication and division of complex numbers.
This video continues looking at dividing complex numbers by looking at the conjugate of a complex number. The instructor then uses the conjugate to rationalize the denominator of a rational expression with a complex number in the denominator. (Although, he doesn't use the terminology "to rationalize the denominator.") He ends the video by challenging the listener to graph the complex numbers in the complex plane and the results after addition, subtraction, multiplication, or division. Doing so, will help give learners a good visual representation of what each of those operations accomplishes.
Seventh graders solve problems using order of operation. In this algebra lesson, 7th graders compare and contrast rational and irrational numbers. They create a T-chart to help differentiate between the two.
Seventh graders use a variety of strategies to solve problems with integers, fractions, decimals, and percents. In this number operations lesson, 7th graders discuss sales tax and use grids to represent money and percents. Students shade in the grid to solve percent problems. Students solve sales tax, discounts, and sales price percent problems. Students improve reasoning skills and visualize real world percent problems with the grids.
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.
Using unifix cubes, a spinner, a number line, and fact family triangles second graders will play their way to subtraction competency. They engage in a series of activities that has them playing game that require them to add and subtract single and simple double-digit numbers. They use flash cards, manipultives, fact families, and a number line to show what they know. Several game boards and worksheets are included.
Students write what each of the 4 basic operations mean, provide examples, and solve problems. For this operations lesson plan, students also fill out charts and identify patterns.
Students review numbers, number systems and the number operations through the use of online webpages.
Pupils measure and problem solve to fabricate a multi-step, interactive math-learning tool. They calculate correct number bonds (equations) while using their number wheels. Students comprehend that addition and subtraction are inverse relationships.
Students engage in a lesson that is concerned with the concept of recognizing numbers. They use Crayola Coils to imitate a number that is made from a ball. The activity is especially suitable for students who are kinesthetic.
Young scholars practice the concept of mathematical closure as it relates to even and odd numbers. In this math lesson plan, students perform 4 different tasks to  understand the number closure concept. Young scholars identify, explain, predict, determine, and make  calculations to arrive at correct mathematical conclusions.
Monitor the growth of young mathematicians with a comprehensive addition and subtraction assessment. Using the context of a class field trip to an apple orchard, this series of four story problems allows children to demonstrate their fluency with adding and subtracting two-digit numbers by implementing strategies of their own choosing. Included is a rubric for grading, the answers and work shown for each problem, as well as a graphic organizer for analyzing the results of the entire class. As either a formative or summative assessment, this is an excellent resource that supports teachers in developing the number sense of primary grade students.
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. 
In this whole numbers worksheet, students read through an explanation of how to add, subtract, multiply and divide whole numbers. Then, students answer 60 questions in which they will do one of these operations with whole numbers. Students can click on the "Check" box next to their answer to see if they got it right or wrong. Also, they can click on "Tell Me" to see the correct answer. The worksheet is graded at the bottom of the page.
