Students should have background knowledge of math vocabulary words that indicate operations i. There is a teacher handout attached with commonly used vocabulary that could be used to help review.
What are the guiding questions for this lesson? Please refer to these questions throughout the lesson and class work.
In what operations might the incorrect order of doing the operations provide the wrong answer? Subtraction and division; multiplication and addition What does the variable represent? Insist that students include units when answering this question.
One or more numbers. Why do we use numbers and symbols in math instead of words? The following questions can be utilized throughout the lesson. What operation uses this action?
What does this number represent in the problem? How would you represent this part of the phrase in math language? Does this expression match the word phrase? Why is the ability to translate from English phrases to math language important? How will you use this in the future? How will the teacher present the concept or skill to students?
As an introduction to this lesson, students should be refreshed on vocabulary terms such as sum, difference, product, and quotient as well as the meaning or action of the four operations. The following word situations address the action of the operation without allowing students to pull out numbers without thought and perform an operation.
The teacher should facilitate a discussion about each situation as students reason about what is happening in the situation. Project each problem with a document camera, or if unavailable, the problems could be copied and given to students.
The cafeteria bought lots of frozen pizzas to serve. If you know the total amount of money they spent and how many pizzas they bought, how could you figure out the cost of 1 pizza?
Why do you believe that? What is the action of this operation? You would divide the total cost by the number of pizzas to find the cost of one pizza.
Division separates the money spent into equal stacks. Each stack represents the cost of one pizza. Division separates a quantity into equal parts. Pete bought some candy and gave some of the pieces to his best friend, Hal.
How could you figure out how many pieces Pete has left? Why do you believe this? What is the action of the operation? Subtract the number of pieces he gave to a friend from the number of pieces he purchased.
You are starting with the whole, taking away a part so what is left is the other part. The subtraction action is to take away, or compare by finding the difference.As a member, you'll also get unlimited access to over 75, lessons in math, English, science, history, and more.
