TEACHER: Good morning! Today we’re going to continue our work with zoo animals during math.
STUDENT: Awesome! I brought my toy elephant, rhino, and zebra!
TEACHER: That’s great! Let’s use your toy animals to make word problems. Ready?
STUDENT: Ready!
TEACHER: There are 8 elephants at the zoo. Each elephant eats 9 times during the day. How many times do the elephants eat total per day?
STUDENT: Oh, wow. That’s a lot of eating. I’m not sure how to find the answer.
TEACHER: Let’s see. There are 8 elephants, and each elephant eats 9 times.
STUDENT: Now I know! This is a multiplication problem! We can use equal groups in pictures and an equation to find the answer!
TEACHER: You got it! We have a picture showing 8 groups of 9, and our equation showing 8 times 9 equals something. So, what is 8 times 9?
STUDENT: 8 times 9 equals 72 because there are 72 dots in the circles.
TEACHER: Excellent! 8 times 9 does equal 72. Which numbers are factors in the multiplication equation?
STUDENT: 8 and 9 are the factors.
TEACHER: Good work. Do you know which number is the product?
STUDENT: Yes! A product is the multiplication answer, so 72 is the product.
TEACHER: You’re on a roll! Let’s do another word problem! There are 6 rhinos at the zoo. Each rhino gets 7 cabbages to eat each day. How many cabbages do all of the rhinos eat each day?
STUDENT: This sounds like another multiplication problem. I think I need to solve 6 times 7. Can you draw a picture to help me?
TEACHER: Absolutely! I’ll draw 6 circles for the 6 rhinos and 7 dots for the cabbages.
STUDENT: Thanks, that helps me a lot! Now all I need to do is count the dots. Let’s see…I think I’ll skip count! 7, 14, 21, 28, 35, 42. 6 times 7 equals 42!
TEACHER: Well done! 6 and 7 in this multiplication sentence are the factors, and 42 is the product.
STUDENT: This is fun! Can we do one more?
TEACHER: Yes! Let’s see if you can write an equation and draw a picture to solve this word problem. There are 7 zebras at the zoo. Each zebra walks 10 miles. How many total miles do the zebras walk?
STUDENT: I think I can do this! My equation will be 7 x 10 = what for 7 zebras walking 10 miles each. Then, I’m going to draw 7 circles for the 7 zebras. In each circle I’m going to draw 10 lines for each mile that each zebra walked.
TEACHER: OK, you have your equation and your picture. What is 7 times 10? What is the product?
STUDENT: Is it 63?
TEACHER: Hmm, not quite. How can you check your answer?
STUDENT: Oh, yes! I can count the lines in my circles. Let’s see…70! 7 times 10 equals 70.
TEACHER: Correct! The zebras walk a total of 70 miles.
STUDENT: Drawing pictures to show my equations sure does help me multiply. Thanks, Ms. Renard!
