Multiple Ways to Represent Numbers
Students will play a game to practice reading and writing numbers within 1000 in different forms. They will use standard form, baseten numerals (blocks), word form, and expanded form. 
NC Mathematics Standard(s):
Number and Operations in Base Ten
Numbers Base Ten
NC.2.NBT.3 Read and write numbers, within 1000, using baseten numerals, number names, and expanded form.
Standards for Mathematical Practice:
2. Reason abstractly and quantitatively
4. Model with mathematics
5. Use appropriate tools strategically
6. Attend to precision
7. Look for and make use of structure.
Student Outcomes:
 I can read and write numbers up to 1000, using baseten, number form, and expanded form.
 I can check my partner’s work.
Math Language:
What words or phrases do I expect students to talk about during this lesson?
base ten, standard form, number names or word form, expanded form
Materials:
 A set of game cards, a number cube (die), a game board, and 2 game pieces for each pair of students
 Base ten blocks
 Paper and pencil or a whiteboard and dry erase marker for each student
 An anchor chart or list of numbers in word form to be used to aid students in spelling
 Optional anchor chart showing the number forms like the sample shown.
Advance Preparation:
 Students should have had prior experiences with standard form, expanded form, word form, and base ten blocks.
Launch:
Numbers to 1000 (5 minutes)
 Write 863 on the board for students to see. Ask them to read the number out loud. Ask if they know what form that number is written in. (standard form) If the students aren’t able to give this answer, then review this term and give several more examples. Ask why they think it is called “standard” form? (It is the normal or usual way of writing a number)
 Review expanded form, how to draw base ten blocks, and how to write numbers in word form. Draw students’ attention to the anchor chart with numbers in word form. Remind them to use it to help them spell when writing numbers in written form.
 Introduce the game and how to play. Each player will place a game piece on start. Players should roll to see who goes first. Player 2 will pick up the first card, holding it so that player 1 cannot see the answer, and read the directions on the card. The first player will then write the answer on their whiteboard or paper. Then they should explain their answer to their partner, who tells them if they are correct or not. If the partner agrees that you answered the task correctly, roll one number cube and then move that number of spaces. If the answer is incorrect, you do not move your playing piece. It is then the other player’s turn. The winner is the first player to reach the finish line. You do not need to have an exact roll to get to finish.
** Teacher note – If students go through the deck of cards before reaching finish, they should shuffle them and reuse those cards to continue the game.

Students will work with a partner to play the game. The teacher should rotate around the room and observe students.
Observation  Next Steps 






Questions to ask:
 How do you know what number this represents?
 How are the numbers represented in different forms?
 Are you having difficulty with any of the number forms?
 Why did you represent ______ this way?
 What does this digit represent in your number?
Discuss:
 Reflection(5 minutes)
Have students clean up their game and come back to the group. Ask students to share how their game
went.
 What were you able to do well?
 What did you find hard at first?
 Ask students when you might see numbers written in word form? Expanded form? Standard form?
(word form – articles, books; expanded form – check; standard form – everywhere)
 How can understanding expanded form help us to understand 2 and 3digit numbers?
 Did you find that the task got easier as you played the game?
Evaluation of Student Understanding
Informal Evaluation: Observe partners as they work. Are they having difficulty with anything?
Formal Evaluation/Exit Ticket:
Give students a 3digit number orally. Have them write the number in standard form. Then have them write it in expanded form and word form, and then draw it with base ten blocks.
Meeting the Needs of the Range of Learners
H T O 
Intervention: If students are having trouble, try making a hundreds, tens, and ones (HTO) chart. Show students how to separate the digits of a 3digit number in the chart. Help them to see how this chart shows them how many hundreds flats, ten rods, and ones cubes that they need. Then help them to use those base ten blocks to write it in expanded form.
Extension: Add the Monkeying Around With Numbers game to math stations or centers.
Possible Misconceptions/Suggestions:
Possible Misconceptions  Suggestions 
Student has difficulty remembering the difference between standard and expanded form  Provide the student with a written definition and example of each term or refer them to the anchor chart that you created. 
Student is having difficulty drawing the base ten blocks or writing the number in expanded form  Provide base ten blocks for the student to use. It may also help to have a workmat that has spaces for hundreds, tens and ones.
