The other two are open ended to match the writing algebraic expressions to statements part of the objective. I expect for there to be some disagreement over several of these since they all use 10, 15 and x.
We will briefly discuss answers before beginning the exit ticket. The product of four less than a number and three more than a number is equal to two less than eight times the number. The last two are 2-step expressions which is right where the common core expects 7th grade students to be.
I will set the timer for about minutes before rotating. What question could the expression answer? Questions If five is decreased by the sum of n and 2, the result is 1. The sum of a number and twice that number is 14 more than the number. The first two problems are one-step expressions and the last two are two-step expressions.
An equation is two algebraic expressions combined with an equals sign. If the population of Oxford increases by every year for 10 years, the resulting population is twice the original population.
This activity should bring about all of the misconceptions. Once all of the statements have been placed we will discuss the responses. Well, there are a few keywords that often are used to represent "equals". They are to pick the expression that they think best matches the statement.
Assign this reference page Click here to assign this reference page to your students. The ratio of x to 7 is four less than x. Equation 3 Here the "equals" word is "yields. Equation 1 The phrase "add up to" breaks the problem into two parts.
If the temperature starts at 32 degrees, and increases at a rate of 4 degrees per hour for a certain number of hours, the resulting temperature is 92 degrees.
They should place their sticky note on that expression. A successful exit ticket will be measured as at least 3 correct responses out of 4. How do you know where to put an equals sign?
The first 4 problems are 1-step expressions. Some of these are listed below: For each expression we will discuss what each part coefficient, constant, variable, operations, etc represents.
Two are multiple choice to represent the matching algebraic expressions to statements part of the objective. Four less than four times a number is equal to the square of that number. I purposely did not include a question with the statements, so that for each I can ask:3.
Lisa is coloring her creation. The blue color used is 50% of the green color used, yellow is 5% of the blue color used, and brown is 7% of the amount of green used. She wants to find the total amount of color used by her.
