Discovering Math: Computation
Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate expressions. Note: the associate video is only available via purchase, but the other activities hold enough value to support the lesson without it.
What are Inverse Operations?
Explore inverse operations. Video viewers watch as a teacher shows how to "undo" an operation by using the opposite operation. By the end, learners should grasp that addition is the opposite of subtraction and division is the opposite of multiplication. You might build context and let pupils know when they will need inverse operations.
Simplifying Expressions (Addition and Subtraction)
Seventh graders simplify algebraic expressions using addition and subtraction to combine like items and solve for the variable. They work with inverse operations to solve equations with guided practice. Everyone completes various problems for independent practice.
Using Inverse Operations to Solve Equations
Fifth graders discover how to use inverse operations to solve equations. In this inverse operations lesson, 5th graders explore visual examples. Students also practice solving problems that their instructors model.
Using Knowledge of Inverse Operations to Solve Algebraic Word Problems
Fifth graders explore the concept of inverse operations. In this algebra lesson, 5th graders use part, part, whole model to describe inverse operations. Students solve equation problems and word problems as they apply their knowledge of inverse operations.
Solving Single-Variable Equations Part II
Brainiacs explore the concept of solving single-variable equations.They use inverse operations to solve equations, and participate in activities such as balancing an equation scale. This is an awesome lesson, complete with game transparencies, worksheets, and multiple pdf attachments.
Using inverse Operations to Solve Equations
Fifth graders solve equations. In this algebraic equations lesson plan, 5th graders use the inverse operation to solve an equation. The teacher reminds students to perform the operation on both sides of the equation. This lesson plan follows a teacher script.
Dr. Al Gebra
Young math whizzes role play a doctor operating on a patient without diagnosing the patient's condition. They relate this medical malpractice to performing a mathematical operation before evaluating conditions or deciding what the outcome should be.
Performing Operations With Signed Integers
Need a great activity to get your class performing operations with signed integers? Here are six different worksheets to use with lessons on adding, subtracting, multiplying, dividing, and problem solving with integers. This would also be great to use as for reviewing these concepts with your class.
Solving One Step Equation
Students solve one step equations. In this algebra lesson, students solve linear equations using division, multiplication, subtraction and addition. They investigate the correct way to keep an equation balanced.
Equations and Formulas
Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra learners practice solving equations with multiple variables. This could also be good practice for science class.
In this inverse operations worksheet, students solve equations using inverse operations. A detailed example and explanation is available prior to the exercises. This two-page worksheet contains four problems.
Introducing the Concept: Adding and Subtracting With Negative Integers
A basic narrative is outlined for teaching a activity on the addition and subtraction of integers. Using a number line, you can demonstrate how to find the sum of a positive and negative integer. On the right side of the page are links to subsequent lessons in the use of negative integers.
Third graders apply real world knowledge of how to undo something to addition and subtraction. In this inverse lesson, 3rd graders write the inverse of number problems. Students use inverse number sentences in word problems. Students complete several worksheets.
Solving Equations How Sweet it Is.
Eleventh graders solve one and two step algebraic equations. In this algebra lesson, 11th graders solve equations using multiplication, division, addition and subtraction. They model solving equations using candy so the students can see what is going on instead of just memorizing the rules.
Introducing Two-Step Equations
Your class always thinks they know what's on your mind. How about testing them on this with these math riddles? For example, "I'm thinking of the number that when multiplied by eight and then two is added, the result is 58?" is a great introduction to creating and understanding multiple-step equations. Understanding the role of variables to represent quantities, as well as the importance of grouping symbols, and solving real-world problems are all covered.
Use this complete lesson plan to introduce geometers to inverse trigonometric functions. Learners use trigonometric ratios to solve triangles when an angle measure is known, then explore using the inverse process when only side lengths are given. The exploration naturally leads to a discussion about use of the inverse trigonometric function keys on the calculator. The lesson also includes five practice problems, three of which are real-world scenarios. Each practice problem has multiple parts.
MULTIPLYING AND DIVIDING FRACTIONS, TEACHER'S GUIDE (7, SAXON MATH, Pp. 25-28)
In this teacher's guide to the multiplying and dividing fractions worksheet, learners learn that fractions are converted to decimals on a calculator. Students have guided practice multiplying a fraction by a whole number; multiplying a fraction by a fraction; and dividing fractions and mixed numbers, all on a calculator.
Models for Dividing Fractions - Grade Six
Fifth and sixth graders use food and candy to help them represent division of fractions and develop algorithms to solve fraction problems. They discuss dividing whole numbers by fractions. Pupils use sticks and chocolate bars to study fractions. Everyone writes number sentences about fraction division problems and creates algorithms to solve equations.
Solving One Step Equations
Students solve linear equations using one step. In this algebra lesson, students solve problems using addition, subtraction, multiplication and division.
