Tallying Our Shoe Sizes

Find out your own shoe size if you don’t already know it. Now, let’s collect the shoe sizes of everyone else in your house into a tally chart.

Now we have collected our information, we need to present it in a way that makes it easy to understand.

Think about the bar chart we looked at earlier. Could we present our data in a similar way?

• Horizontal bars
• Scale (going up in 2s,

3s, 4s, 10s, etc.)

• Use a different colour

for each different bar
