Each friend gets the same number of pencils.

Multiple Choice

Which picture matches the story?

Multiple Choice

How many pencils did he give each friend?

• 9

• 18

• 6

• 3

Poll

How did you solve the problem?

• I made an array with 2 rows and kept adding columns while counting by 2s until I got to 18. Then I counted how many columns I made.

• I used 18 counters and made two piles by moving my counters until both groups had the same amount. Then I counted how many were in the group.

• I knew since there were two people I could use a doubles fact and 9+9=18

• I circled groups of 2 and saw that I had nine groups. I knew that if I have nine groups of 2, I could also make 2 groups of 9 so each person would get 9.

We did it!

We reached the end of the review!

• Yes! I feel super ready!

• Mostly ready, but I'd like more practice some more on my own!

• Almost ready, but I want to practice with you some more during the rest of class!

• I don't feel ready, can we meet one on one for more help afterschool?
