Tally Charts

tally chart is an easy way of recording data.  It involves filling in a chart with groups of lines representing each piece of information you observe.  Tally charts are quicker than writing out words or numbers.  

Here's how you quickly record your data by using the lines instead of numbers. Notice that every fifth line is a strike through the previous four lines and you then start a new group of lines. 

What is the total number of each of these tallies?

Now, let's put your tallying skills to the test. You are going on safari to Africa. One by one, note down in your tally chart when you come across a different animal. Then count up your tally to get the total number of each animal you saw on the safari.
