Today, I will build whole numbers from 51 to 100 using base ten
Vocabulary
Teacher Resources
Base ten blocks:
Considerations: Students are provided academic vocabulary and a place value chart on page 1 of the Student Journal.
Steps: 8 tens = 80
6 ones = 6
8 tens + 6 ones = 86
1. Identify the number in the tens place. Build it and record how many. 2. Identify the number in the ones place. Build it and record how many. 3. Count by tens and then count on by ones. Record the whole number
Application of MPs: MP1:
How did you prove your answers?
MP2: What math expression was used to represent the situation? MP4: How would you change your model if you added a ten?
/ *MP1: Make sense of the problem and persevere in solving it! *MP8: Find a strategy to help solve the problem. Teacher: Provide students with base ten blocks to build the numbers. Directions: Use base ten blocks to build numbers from 51 to 100.

State the objective: Today, I will build whole numbers from 51 to 100 with base ten blocks.
Explain how to build the number 63 with base ten blocks.
Represent 63 with 6 base ten blocks and record 6. Then, represent 3 ones and record 3.
Demonstrate counting by tens (10, 20, 30, 40, 50, 60) while pointing to the blocks.
Demonstrate counting on by ones from 60 (60…61, 62, 63) while pointing to the blocks.
Record the whole number 63.
1. Build the number 80 with base ten blocks. Record the whole number. tens +
ones =
Explain how to build the number 80 with base ten blocks.
Represent 80 with 8 base ten blocks and record 8. Then, represent 0 ones and record 0.
Demonstrate counting on by tens (10, 20, 30, 40, 50, 60, 70, 80) while pointing to the blocks.
Directions: Directions: Use base ten blocks to build numbers from 51 to 100.
1. Build the number 82 with base ten blocks. Record the whole number.

2. Build the number 60 with base ten blocks. Record the whole number.
tens +
ones =
*MP3: Do you agree/disagree with what
said?
*MP6: How do you know your answers are correct/reasonable?
Recap today’s lesson with one or more of the following MP questions: MP1: How did you prove your answers? MP2: What math expression was used to represent the situation? MP4: How would you change your model if you added a ten?
