Fill in your binder reminder with: Math: 3. 1. 3 Homework 3 -45, 3 -46, 3 -47, and 3 -49 Science: 4. 5 Reading & Notetaking page Study for ch. 4 exam on Friday!!! Resource Managers: Get your team’s notebooks In your math notebooks, just below where you finished Thursday’s notes, write today’s date and ANSWER THE FOLLOWING: -Write your own definition of the word “percent. ” -Describe at least one method to find a percent from a sample.

• In math, there is often more than one way to express a value or an idea. For example, the statement, -“Three out of ten students who are going on the field trip have turned in their permission slips, ” communicates the same portion as the phrase, -“ 30% of the students who are going on the field trip have turned in their permission slips. ” While three out of ten and 30% might look and sound very different, they are both representations of the same portion of a whole. -(In this case, the whole is the entire number of students who are going on the field trip. )

-Remember back in our previous lesson how each of your teams guessed the portion of the jar that was filled with red beans?

-While they may look like very different numbers, each pair communicates the exact SAME PORTION of a whole.

• Throughout chapter 3 section 1, we have been representing numbers in different ways. • In Lesson 3. 1. 2, we used a diagram and a percent ruler to express your team’s guess about the portion of red beans in a jar.

• In lesson 3. 1. 2, we will use a 100% block to create models of the size of various numbers on the 100% block. • Today, we will be investigating several ways to represent portions of wholes, including percents, fractions, and decimals. • As you work, keep these questions in mind: • How can I build it? • Is there another way to represent this portion? • What is the whole?

A few weeks ago, we used a hundred block to represent the number 100. For our work in this section, we will use this block to represent: -one whole -100% -100/100 -1 -one hundred out of one hundred.

3 -36. BUILD IT, DRAW IT, WRITE IT, SAY IT • If the large square block represents 100%, what do each of the other blocks you have worked with represent? 100% One Whole

3 -36. BUILD IT, DRAW IT, WRITE IT, SAY IT Resource Managers: Come get two sets of base 10 blocks for your team Recorder Reporters: Come get four copies of the Build it, Draw it, Write it, Say it sheet from me!

3 -36. BUILD IT, DRAW IT, WRITE IT, SAY IT For each of the portions listed below: -Build the portion on a 100% block. -Draw a diagram of the portion on your resource page. -Write the portion in at least two different equivalent representations. -Write out how you could use words to say or name the portion two different ways. a. c. d. 80 pieces out of 100 total pieces 150%

a. Let’s work out problem a. together! -Build the portion on a 100% block. -Draw a diagram of the portion on your resource page. -Write the portion in at least two different equivalent representations. -Write out how you could use words to say or name the portion two different ways. Now, complete b, c & d with your partner! c. d. 80 pieces out of 100 total pieces 150%

3 -37 Answer the following with your TEAM Erik and Tate cannot agree on the amount shaded on the 100% block shown below. -Erik says, “It shows 2 tenths of the 100% block… and 3 hundredths of the block, ” -Tate says, “It shows 23 hundredths of the whole block. ” a. What would you tell Tate and Erik? Justify your response with words and pictures. b. Another representation of the number shown on the 100% block above is a decimal, which would be written as 0. 23. What does the 2 stand for and what does the 3 stand for?

3 -38 If 0. 23 can be represented with 2 tenths and 3 hundredths, a. How can the number 0. 19 be represented? b. What about 0. 5? -Draw a picture of each of these numbers on the 100%-block diagram page.

a. Is she correct? b. Why or why not?

3 -42 Guess My Decimal Maya and Logan invented a new game called “Guess My Decimal. ” One of them thinks of a decimal and gives the other a clue to solve for the mystery decimal. a. Logan said, “First, I think of the 100% block as a ONE block so I can make a decimal instead of a percent. Then my decimal can be represented on the one block like this. ” He pointed to the diagram at right. What is Logan’s decimal?

3 -43 Complete on the sheet you were using yesterday!

3 -44 Jonah wonders about other representations of numbers on the 100% block. He calls this figure “twelve-and-a-half hundredths. ” Use his drawing to help answer the following questions. a)How could this be expressed as a percent? b)What fraction of an entire 100% block is shaded? Is there more than one way to write this fraction? c)How could this number be written as a decimal? *End of 3. 1. 3 Day Two*
