STRATEGY

When I was in school, we had a set of steps for problem-solving. Some teachers would change it up a little, but most were pretty close to:

1. Understand the Problem 2. Come up with a Plan for Solving 3. Carry out the Plan 4. Reflect or Check Your Work

These steps are better known as Polyas Problem Solving Approach and were developed by George Polya in 1945. Although these steps always sounded like a good idea and did get students thinking through the math problems they were facing, they didnt always get the job done

What happens when you cant get past step 1? You read the problem over and over and still cant make sense of it. You listed out the known information, you underlined the key terms and circled the numbers, but you just cant figure out what to do. Under this problem solving approach you are expecting students to understand the problem before making any drawings, diagrams, tables, patterns, etc., which can leave many students fumbling to make sense of it all.

This is where the Read, Draw, Write approach comes in to play. Here is the basic idea of this strategy:

3. WRITE your conclusions based on the drawings. This can be in the form of a number sentence, an equation, or a statement.

Use the RDW process to solve the problems below. Use a letter to represent the unknown in each problem. When you are finished, share your solutions with a partner. Discuss and compare your strategies with your partners strategies.

Question 1.Monica measures 91 milliliters of water into 9 tiny beakers. She measures an equal amount of water into the first 8 beakers. She pours the remaining water into the ninth beaker. It measures 19 milliliters. How many milliliters of water are in each of the first 8 beakers?

Answer:Amount of water Monica pours into each of the first 8 beakers = 9 milliliters.

Explanation:Amount of water Monica measures into 9 tiny beakers = 91 millilitersAmount of water in ninth beaker = 19 millilitersAmount of water Monica measures into 8 tiny beakers = Amount of water Monica measures into 9 tiny beakers Amount of water in ninth beaker= 91 19= 72 milliliters.Amount of water Monica pours into each of the first 8 beakers = Amount of water Monica measures into 8 tiny beakers ÷ 8= 72 ÷ 8= 9 milliliters.

Question 2.Matthew and his dad put up 8 six-foot lengths of fence on Monday and 9 six-foot lengths on Tuesday. What is the total length of the fence?

Answer:Total Length of the six-foot fence Matthew and his dad put up on Monday and Tuesday = 17.

Question 3.The total weight of Lauras new pencils is 112 grams. One pencil rolls off the scale. Now the scale reads 105 grams. What is the total weight of 7 new pencils?

## What Do A Tape Diagram Look Like

A tape diagram is a rectangular drawing that appears like a tape piece with divisions to support mathematical calculations. It is a graphic tool used commonly in solving ratio-based mathematical word problems. Tape diagrams are visual representations that represent the sections of a ratio by using rectangles.

## What Is A Tape Diagram For Addition

A tape diagram is a model to help students visualize the addition or subtraction problem they are trying to solve. Students will learn how to draw and label a tape diagram. They will also have to write an addition sentence explaining the tape diagram, and create their own word problem by looking at a tape diagram.

## How Do You Explain A Tape Diagram Tape diagrams are visual representations that represent the sections of a ratio by using rectangles. As they are a visual model it takes attention to detail to draw them. They break down complex mathematical word problems and help simplify it. They are depicted in the form of a strip or as a piece of tape.

Solve using the RDW process.

Question 1.Michael earns \$9 per hour. He works 28 hours each week. How much does he earn in 6 weeks?Answer:Michael earns in 6 weeks is \$1,512,

Explanation:Given Michael earns \$9 per hour. He works 28 hours each week,means Michael earns in each week is 28 hours X \$9 = \$252,Now in 6 weeks Michael earns \$252 X 6 = \$1,512.Solved using the RDW process as shown above.

Question 2.David earns \$8 per hour. He works 40 hours each week. How much does he earn in 6 weeks?Answer:David earns in 6 weeks is \$1,920,Explanation:Given David earns \$8 per hour. He works 40 hours each week,means David earns in each week is 40 hours X \$8 = \$320,Now in 6 weeks David earns \$320 X 6 = \$1,920.Solved using the RDW process as shown above.

Question 3.After 6 weeks, who earned more money? How much more money?Answer:We got Michael earns in 6 weeks is \$1,512 andDavid earns in 6 weeks is \$1,920 so more amount is earnedby David by \$1,920 \$1,512 = \$408 as shown above.

Question 1.A pair of jeans costs \$89. A jean jacket costs twice as much. What is the total cost of a jean jacket and 4 pairs of jeans?Answer:The total cost of a Jean jacket and 4 pairs of jeans is \$534,

Explanation:Given a pair of jeans costs \$89. A jean jacket costs twice as much,So jean jcket costs 2 X \$89 = \$178,The total cost of a jean jacket and 4 pairs of jeans is\$178 + 4 x \$89 = \$178 + \$356 = \$534.

Question 2.Sarah bought a shirt on sale for \$35. The original price of the shirt was 3 times that amount. Sarah also bought a pair of shoes on sale for \$28. The original price of the shoes was 5 times that amount. Together, how much money did the shirt and shoes cost before they went on sale?Answer:Together,the shirt and shoes cost before they went on sale is \$245,

Explanation:Given Sarah bought a shirt on sale for \$35. The original price of the shirt was 3 times that amount means the original price of the shirt is 3 X \$35 = 1X 5\$140,Together,the shirt and shoes cost before they went on sale is \$105 + \$140 = \$245 as shown above.

Question 3.All 3,000 seats in a theater are being replaced. So far, 5 sections of 136 seats and a sixth section containing 348 seats have been replaced. How many more seats do they still need to replace?Answer:Total more 1,972 seats needs to be still replaced,

## What Is The Rdw Process

In other words, I see the end result of teaching a systematic approach to problem solving, what we refer to as Read, Draw, Write, or RDW. This enables them to solve problems accurately. In this process, we ask students to read the problem and think about what information is given.Apr 10, 2015

What does RDWW mean in math?, One strategy we will be using this year is RDWW, which stands for: Read. Draw and label. Write an equation. Write a word sentence or statement.

Furthermore, What does a tape diagram look like?, A tape diagram is a rectangular drawing that appears like a tape piece with divisions to support mathematical calculations. It is a graphic tool used commonly in solving ratio-based mathematical word problems. Tape diagrams are visual representations that represent the sections of a ratio by using rectangles.

Finally, What does a tape diagram look like in math?, A tape diagram is a rectangular visual model resembling a piece of tape, that is used to assist with the calculation of ratios. It is also known as a divided bar model, fraction strip, length model or strip diagram. In mathematics education, it is used to solve word problems.

2nd Grade Math – RDW Process #1

Use the RDW process to solve the problems below. Use a letter to represent the unknown in each problem.Question 1.Jerry pours 86 milliliters of water into 8 tiny beakers. He measures an equal amount of water into the first 7 beakers. He pours the remaining water into the eighth beaker. It measures 16 milliliters. How many milliliters of water are in each of the first 7 beakers?

Answer:Amount of water he pours equally into the each first seven beakers = 10 milliliters.

Explanation:Amount of water Jerry pours into 8 tiny beakers = 86 millilitersAmount of water he pours into the eighth beaker = 16 millilitersAmount of water he pours into the first seven beakers = Amount of water Jerry pours into 8 tiny beakers Amount of water he pours into the eighth beaker= 86 16= 70 milliliters.Number of first beakers = 7Amount of water he pours equally into the each first seven beakers = Amount of water he pours into the first seven beakers ÷ Number of beakers= 70 ÷ 7= 10 milliliters.

Read, Write, Draw RDW is a suggested method of instructional delivery. Mathematicians and teachers suggest a simple process applicable to all grades. RDW is a four step problemsolving process that supports students through both visual and kinesthetic accommodations. The RDW strategy allows students to closely read and unpack the problem to develop a deeper understanding of the mathematical concepts.

Read, Draw, Write 1. Read the problem. 2. Draw a picture representing the problem. 3. Write a number sentence to solve a problem and a statement answering the problem.
