Activity on standard and expanded form - math grade 2 - lesson 26

For the past few days, we have been working hard to learn different ways to write numbers. We learned about standard form, word form, and expanded form. Today we are going to play a game to help us learn how to read these different numbers better and faster. The game is called I Have... Who Has...?

Note to the Teacher: In today’s lesson, students play the game I Have... Who Has...? If you have 30 or fewer students, follow the procedure below. If you have more than 30 students, adjust the procedure as follows: After you demonstrate how to play the game, divide your class into large groups and give each group their own set of game cards. Instead of playing the game together as a class, they will play in large groups. If you have 31 to 40 students, consider adding cards to the set of game cards so that everyone can play together. See the I Have… Who Has? Game Cards Blackline Master for blank cards.

1.TEACHER SAY: I am going to hand out a card to each student.

TEACHER DO: Hand out one I Have... Who Has...? game card to each student.

TEACHER SAY: Th ere are two sentences on each card. They say, “I have ____.” and “Who has _____?” I will go first. I will read my card aloud. You will listen carefully to see if you have the card I am looking for. I have 224. Who has 300 + 50 + 3? I am looking for the person who has the standard form of 300 + 50 + 3. If you have a card that says, “I have 353,” then it is your turn to stand up and read your card aloud. We will keep playing until everyone has read his or her card.

STUDENTS DO: Play I Have... Who Has...? with the class or group.

TEACHER DO: Th is may be challenging for students the first time they play. If students are playing on their own, walk around and help students who need support. If time allows, mix up the cards and have students play again.
