Frequency Table Lesson

Reading a Frequency Table

I can solve and evaluate two-step problems using data in a frequency table.


4.9B

A choir class with students from third, fourth, and fifth grade was asked about their shoe sizes. The results of the survey were recorded in this graph here. How many more students with a shoe size of less than size 7 are there than students with a shoe size of size 7 or greater?

Let's do another one

Multiple Choice

A choir class with students from third, fourth, and fifth grade was asked about their shoe sizes. The results of the survey were recorded in this graph here. How many more students with a shoe size of less than size 7 are there than students with a shoe size of size 7 or greater?

What is the question asking?

• How many more students with a shoe size of less than size 7 than students with a shoe size 7 or greater?

• How many grade levels are in choir class?

• What is the graph asking you to do?

Let's do another one

Multiple Select

A choir class with students from third, fourth, and fifth grade was asked about their shoe sizes. The results of the survey were recorded in this graph here. How many more students with a shoe size of less than size 7 are there than students with a shoe size of size 7 or greater?

What information is important?

• How many more...

• shoe size less than size 7...

• than students with shoe size 7 or greater?

• third, fourth, and fifth grade...

This is what we are looking at. We have three categories that are less than size 7 ( 15, 10, 14 students). And we have 3 categories that are 7 or greater ( 7, 9, 13 students).

So far..

We can make another part-part-whole.

What can we draw?

Multiple Select

A choir class with students from third, fourth, and fifth grade was asked about their shoe sizes. The results of the survey were recorded in this graph here. How many more students with a shoe size of less than size 7 are there than students with a shoe size of size 7 or greater?

What equation could we write to represent this situation?

• Less than = 15+10+14 = 39

• Greater than= 7+9+13 = 29

• Less than = 7+9+13 = 29

• Greater than = 15+10+14 = 39

Multiple Choice

A choir class with students from third, fourth, and fifth grade was asked about their shoe sizes. The results of the survey were recorded in this graph here. How many more students with a shoe size of less than size 7 are there than students with a shoe size of size 7 or greater?

Let's solve!

• 39 - 29 = 10

• 29 - 39 = -10

• 20 - 9 - 30 - 8 = -27
