Show the data we collected. Read the data out loud (to emphasize that it doesn't make sense when read out loud)

Informally re-survey and record the data in a dot plot. As them what the min. max. and most is. Emphasize that this is much easier to "see"

How many people were surveyed? How many people have 3 pets? How many have 1 pet?

Make a dot plot that shows the number of siblings. Identify the min, max and most.

Make a dot plot that shows the number of boxes sold. Identify the min, max and most.

A dot plot is a type of graph that is based on a number line. Each dot represents an individual data point. It makes it easier to see the data.

How to make a dot plot (a.k.a line plot):

1. Identify min. and max. (range)

2. Create a number line that represents the range of the data

3. For each data point, make a dot (or x) -- neatly spaced -- above the number

4. When finished, count the number of items in the data set and verify that you made the number of dots

1. Make notes for your forgetful selves

2. In your notebook, use the data sets below to create a dot plot. Then identify the min, max, and most.

A. Daily high temperatures: 71, 72, 74, 72, 72, 68, 71, 67, 68, 71, 68, 72, 76, 75, 72, 73, 68, 69, 69, 73, 74, 76, 72, 74

B. Number of tornadoes: 0, 0, 2, 1, 0, 1, 1, 0, 2, 1, 0, 0, 6, 0, 0

C. Length of summer camps in days: 7, 7, 12, 10, 5, 10, 5, 7, 10, 9, 7, 9, 6, 10, 5, 8, 7, 8

D. Estimates of room lengths: 10, 13, 15, 16, 17, 11, 13, 15, 16, 17, 12, 14, 15, 16, 18, 12, 14, 15, 17, 18, 13, 14, 15, 17, 25

3. When you don't understand, look at textbook examples (review the pages prior to the CYUQs) or search

How did the CYUQs go yesterday?

Work with your group to create a dot plot that displays data from our class' survey.

Model how to create a histogram with ranges of ten based on ages at a graduation party (10 items) 12, 30, 37, 22, 41, 45, 5, 35, 38, 13

What is the frequency of grades between 60 and 80?

How many students have shoe sizes between 10 and 11?

Work with your group to create a histogram for the following data:

Points scored in a weekend tournament (15 values) 7, 42, 19, 33, 31, 48, 25, 4, 39, 21, 2, 34, 36, 28, 9

A histogram is a type of bar graph that organizes data into equal buckets (ranges). In addition to helping us to see the data, it makes it easy to see the frequency distribution.

To create a histogram:

1. Based on the data, determine the size of the buckets (ranges): 5, 10, 15, ... ?

2. Setup a graph with the buckets (ranges) on the x-axis and the frequency on the y-axis (remember to write labels)

3. Place each data point in the correct bucket (range)

Bar graph vs histogram:

1. In your notebook, make meaningful notes for your forgetful selves

2. CYUQs → Do in your notebook. You chose where you want to start. Check your work with the students around you and if you need help, get help. And if someone else needs help, give help.

When making a histogram:

Be sure your columns are straight

Be sure to label the y-axis "frequency" and add a label to the x-axis that describes what the data represents

Each bucket must have the same range (i.e. if you go by 10's, all ranges are by 10's)

Another way to show the range is to write it below the "bucket"

When making your histogram, be sure your buckets hold more than one number (a dot plot already goes by 1's)

Work with your group to create a histogram for the following data:

Age of people at a birthday party (20 values) 42, 5, 28, 34, 12, 56, 18, 25, 3, 47, 13, 44, 9, 39, 30, 22, 47, 2, 23, 8

Time it took to run a mile (minutes and seconds) (12 values) 6:45, 7:12, 8:03, 6:38, 7:50, 9:01, 8:27, 6:55, 7:18, 8:10, 9:30, 7:45

CYUQs: In your notebook, create a histogram for the two data sets (below). Check your work with the students around you and if you need help, get help. And if someone else needs help, give help.

Minutes spent doing math homework (25 values) 11, 53, 47, 44, 3, 31, 55, 19, 50, 6, 38, 22, 28, 59, 2, 49, 14, 41, 12, 33, 16, 35, 13, 48, 29

Rainfall amounts (inches) (15 values) 22.3, 18.5, 27.9, 24.7, 22.1, 16.8, 26.5, 19.7, 21.4, 20.9, 17.4, 25.1, 23.6, 21.5, 30.0

Dot Plot

Histogram

This is what students noticed:

It's time to use what you've learned to represent our data visually.

When you receive your worksheet, neatly write your first and last name in the corner above the lists of data.

Create one dot plot and one histogram (each based on a different data set). INCLUDE LABELS.

when making your number lines, use a ruler to make the spacing (intervals) the same

Use pencil ONLY. Write neatly.

* If you were absent or lost your paper, pick one of the following and print a single page from your class period:

Today you will begin your first of three Renaissance STAR Math assessments (during your 6th grade year).

This is an adaptive test. Everyone has different questions. Sometimes a question will seem difficult (and you've never learned it). Do your best. If needed, guess. The software is trying to figure out your math level.

Don't rush. But don't go slow. Each question is timed: you have at most 3 minutes.

When finished, put your scratch paper (WITH YOUR NAME ON IT) in the basket in the back. You may read (SORA), draw, write, or do another quiet activity. Do not talk.

Please take everything off your desk except for something to write with and your chromebook. Go to Clever > Renaissance Star Math Benchmark

* To see your score: scroll down to the bottom of their Renaissance home page. Click on “Get email updates” then on Progress in upper right corner. Scroll all the way to the bottom of the page.

If you have not turned in your dot plot and histogram, please put it in the basket in the back of the room.
