A ticket to enter the zoo is seven dollars. Three people are waiting to buy tickets. How much will their tickets cost in total?
The first sentence of this problem tells us that a ticket to get into the zoo costs seven dollars. The next sentence tells us how many people want to buy these tickets. Three people are waiting to buy tickets, and so the total cost of their tickets will be worth three lots of seven. We could find the answer by adding seven three times. But a more efficient method is to use our knowledge of the seven times table. What are three sevens?
Let’s remind ourselves of the seven times table facts. One times seven equals seven. Two times seven equals 14. And three sevens are 21. 7, 14, 21. We used our knowledge of the seven times table to find the answer. If a ticket to enter the zoo is seven dollars and if three people are waiting to buy tickets, we can find the total cost of their tickets by multiplying three by seven. Three times seven is 21. And so, the total cost of their tickets is 21 dollars.
