12 = 3 × 4
Anna has four marbles. Ben has three times as many marbles as Anna. How many marbles does Ben have?
Here are Anna's four marbles.
Ben has three times as many. That's one group of four...
...two groups of four...
...and three groups of four.
Three groups of four equals twelve. So Ben has twelve marbles.
We can write this as twelve equals three times four.
This equation tells us twelve is three times as many as four.
When we see times as many, we multiply. Ben has twelve marbles!
