In this 3rd grade video on scaled picture graphs

It’s laundry day for Nari and Gus, but they have a problem. They need to sort all their clean laundry before putting it away. In this video, we help Nari and Gus organize their newly clean clothes by making scaled picture graphs.

What is a scaled picture graph?

Let’s learn more about scaled picture graphs and how we draw one below.

Scaled picture graph definition

A scaled picture graph is a type of graph that uses pictures to represent and sort information into categories. The value of one picture represents more than one item. This allows the graph to show more information at once.

How do you make a scaled picture graph?

We start drawing a scaled picture graph by identifying our data set. This is the information that we organize and display in the graph. It is important to give this data a name to explain what it represents. This name becomes the title of our graph and will tell our readers what it is about.

Next, we sort the data set into categories. Each category becomes one row in our graph. If we have three categories, we will need three rows in the graph. Each row is also labeled with the name of the category on the scaled picture graph.

Afterwards, we chose a picture, or image, to represent the data. Because we are making a scaled picture graph, one picture will represent more than one data point. We decide the value of one picture by looking for common multiples in the data set. For example, if most of the numbers in the set can be made counting by twos, the common multiple would be two! Once we have determined our common multiple, we write this information in the key. This tells our readers the value of each picture in the scaled graph.

The last step is displaying the set of data in the scaled picture graph. Going row by row, we draw the correct number of pictures for each category. It is important to use the interval written in the key so that each row has the right number of pictures. If we have ten data points in the first row and our scale is one picture equals two, we divide ten by two. This tells us we need five pictures to represent the data in that row.

What does a scaled picture graph look like?

Below are scaled picture graph examples.

Summary of Steps: Making a Scaled Picture Graph

  • When drawing a scaled picture graph, first identify and name thedata set.

  • Then, sort the data into categories and draw the chart.

  • Next, define the scaled pictures by looking for common multiples and note it with a key.

  • Finally, plot the data into the graph according to the key’s scale.

Transcript Scaled Picture Graphs

"What is that?" "I don't know, it's not the honey." "Hmm, you know, might be our laundry... it's probably time to change into a new set of clothes anyway." "I can't believe it all fit!" But how will we sort it all?!" "We could make a scaled picture graph to help us organize our clean clothes." Drawing a Scaled Picture Graph. A picture graph is a chart that uses pictures to represent and sort information into categories, that's why it is called a picture graph! In a scaled picture graph, the value of one picture represents more than one item so we can see a lot of information at once. To start our first picture graph, we'll need to find all of Nari's clean clothes in that pile. This is called our data set! Next, we need to give this graph a name. Since the data set includes all of Nari's clean laundry, let's call it, "Nari's Clothes" Next, we sort and count Nari's clothes into categories like shirts, pants, and pajamas. These three categories let us know we need to draw three rows in our graph. Now, we'll make a key for our picture graph using a hanger to represent our clothing items. Remember, we are making a scaled picture graph so one hanger represents more than one piece of clothing. Let's add a key at the bottom of the graph to tell readers that each hanger will represent two pieces of clothing because most of the data can be made counting by 2s. We can also say they are multiples of two. Finally, it's time to fill in our picture graph! Remember, each hanger represents TWO pieces of clothing and Nari has six shirts. Let's skip count together by two's: two, four, six. So, we'll need to put three hangers in the shirts row because two goes into six three times. Let's do the same thing for his pants! How many times does two go into four? Two goes into four two times so that means we will need two hangers in the pants row. Let's be careful with our three pajamas though because two does not go evenly into three. One hanger represents two pajamas, so we can use half a hanger to represent the one left over. Now that Nari's scaled picture graph is complete, we should help Gus! Our new data set is all of Gus's clean clothes. What should we title this graph? "Gus's Clothes" since it's his clean laundry. Next, we sort and count Gus's clothes into shirts, pants and pajamas. Then, we draw the chart for our graph and add our labels. This time let's pick a clothespin to represent our clothing items. REMEMBER, we are making a SCALED picture graph so one clothespin represents MORE THAN one piece of clothing. Gus has six shirts, nine pants and three pajamas so how many items could one clothespin represent? All of those numbers are multiples of three, so one clothespin will represent three pieces of clothing. Now we're ready to fill in his graph! Now let's repeat this for the rest. Gus has nine pants and three goes into nine three times, we will need three clothespins next to the pants label. How many clothespins we will need for Gus's three pajamas? We will use one clothespin because one clothes pin represents three items of clothing. Look(...) All their clothes are sorted and organized, but before we see what Nari and Gus put on let's remember! When drawing a scaled picture graph, first identify and name your data set. Then, sort your “data” into categories and draw your chart. Next, define your scaled symbols by looking for common multiples and note it with a key. Finally, plot your data into the graph according to your key. "Great work today, Gus; let's put on our fresh, clean clothes!" "ahhhhh(...)So comfy!" "I dunno, Nari(...) feels a bit tight."
