Count the stars aloud and then write the number.
One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15. There are 15 stars. We counted each star and found that there are 15. Did you notice that we could count the stars in threes? Three, six, nine, 12, 15. There’s another way we can count the stars. We could count in fives. There are five stars in each column. Five, 10, 15.
The picture shows 15 stars.
