Review place value understanding for numbers within 1,000.
The core standards covered in this lesson
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.
4.NBT.B.4 — Fluently add and subtract multi-digit whole numbers using the standard algorithm.
The foundational standards covered in this lesson
2.NBT.A.1 — Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
2.NBT.A.2 — Count within 1000; skip-count by 5s, 10s, and 100s.
2.NBT.A.3 — Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
3.NBT.A.1 — Use place value understanding to round whole numbers to the nearest 10 or 100.

a. Find 249 in your 1,000 book. Which hundreds page is it on? Which two benchmarks tens is it in between? Which ten is it closer to?
b. I'm thinking of a number. It's on the 400 page. It's close to the number 460. It ends in 2. What number am I thinking of?
