Lesson 3
Objective
Model and write numbers to 10,000 with more than 9 of any unit in standard and unit form.
Common Core Standards
Core Standards
?
-
4.NBT.A.1 — Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
-
4.NBT.A.2 — Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
-
4.NBT.A.3 — Use place value understanding to round multi-digit whole numbers to any place.

Criteria for Success
?
- Regroup 10 units into 1 of the next largest unit on a place value chart.
- Regroup 1 unit into 10 of the next smallest unit on a place value chart.
- Convert between nontraditional unit form (i.e., unit form with more than 9 of any kind of unit) and standard form.
- Identify errors in reasoning related to above (MP.3).
Anchor Tasks

Problem 1
Ms. Glynn wants to model the number 2,213 with base ten blocks, but she only has 1 thousand block, as shown below. She has lots of hundreds, tens, and ones blocks.
How can she make this number using the blocks she has?

Discussion of Problem Set
- Look at #1b. How did you model 2,130 with no more than 1 ten? Is there another way to model it that still meets that criteria?
- Look at #2e. Why is the digit in the ones place a 0, despite the way the number was originally written there were many ones?
- Look at #3. Is Miquel correct? What number was his answer actually equivalent to? How would you fix his answer so that it was correct?
Target Task
?
Problem 1
Jeremy says he can write 1,456 as 14 thousands 56 ones. Is he correct? Why or why not?
Problem 2
Fill out the following table.
| Unit form | Standard form |
| 4 thousands 37 tens | |
| 8 thousands 16 hundreds 33 tens 2 ones | |
| 3 thousands 2 hundreds 4 tens 17 ones |
