## Solving Percent Problems (Day 1)

Enter it here to join a lesson. Create a new lesson with our interactive, multi-media lesson builder.The students will be working on an i llustrative math problem where they will be finding the missing whole using a double number line.

Students can work through the problems independently at first. My goal for this first day is to have student complete the first 6 problems. The students will work through the problem independently. They may use a tape diagram, double number line, or ratio table. Finally, they must explain in words the steps they took to get to the answer and why they took those steps. It helps deepen their understanding of concepts.

This will allow for some peer tutoring to occur. We will complete each problem as a group which means everyone is working on the problem at the same time. SMP 3.

I want the students to think about how well they did with the problems today.

Since students should be familiar with these topics, they will work independently on the problems. What fraction of a mile did Ciara walk her dog? Problem 2 - Students should remember that 28 is equivalent to They may not line up the decimal points and borrow correctly.

Problem 3 - Students can change the mixed number to an improper fraction and divide or they can divide the fractional part and add the 4 wholes to their answer.

For this lesson, students will learn an organized approach to solving percent problems. Students are familiar with ratio tables and we will use this concept to solve percent problems. It is important that students understand what the question is asking for, because it will help them verify if their answer makes sense. Students should realize that the question is asking for a portion of Therefore they can estimate that the answer will be close to but less than This will lead us to fill in the percent column of the table.

In understanding what the question is asking, students have determined that we're missing the part and 50 is the total. We will complete the table. Students should use their previous knowledge and find a multiplicative relationship between the denominators to find the unknown value. We will continue on to more examples. Although each question is worded differently, I will use the same line of questioning so students can understand that ratio tables can work for all percent problems.

Example 4 - Lola was walking down Greene Ave. What percent of the money did she receive as a reward? The Independent Practice is an opportunity for students to solve percent problems independently.In Module 4, students deepen their understanding of ratios and proportional relationships from Module 1 by solving a variety of percent problems.

They convert between fractions, decimals, and percents to further develop a conceptual understanding of percent and use algebraic expressions and equations to solve multi-step percent problems.

Students begin the module by solving problems without using a calculator to develop an understanding of the reasoning underlying the calculations. To develop a conceptual understanding, students use visual models and equations, building on their earlier work with these. As the lessons and topics progress and students solve multi-step percent problems algebraically with numbers that are not as compatible, teachers may let students use calculators so that their computational work does not become a distraction.
