The tally marks show the number of students in a class that play different sports. How many more students play volleyball than soccer?

In this question, we’re shown a tally chart. The chart shows the number of students in a class that play different sports: soccer, volleyball, handball, and swimming. We have to find out how many more students play volleyball than soccer. So, we need to compare the number of students who play soccer to the number of students who play volleyball. When we count using tally marks, we make a group of five in this way to show a count of five.

One group of five is five, and three groups of five are 15. So, the number of children who play soccer is 15. There are four groups of five tallies in the column which shows the number of children who played volleyball. So, we can count in fives to find the total number. Five, 10, 15, 20. Four fives are 20. How many more is 20 than 15? There are five more tally marks. 20 is five more than 15. Five more students play volleyball than soccer.
