By the end of this lesson, you will be able to:
Identify and state the place value (hundreds, tens, ones) of each digit in a 3-digit number up to 999.
Example: In the number 456, the digit 4 is in the hundreds place, 5 is in the tens place, and 6 is in the ones place.
Represent 3-digit numbers using base-10 blocks, place value charts, and expanded form (e.g., 327 = 300 + 20 + 7).
Example: The number 327 can be shown as:
• 3 hundreds blocks + 2 tens rods + 7 ones units
• 300 + 20 + 7
Compare and order 3-digit numbers using place value reasoning (e.g., using >, <, =).
Example: To compare 328 and 342, first look at the hundreds (both have 3), then look at the tens (2 vs 4). Since 2 < 4, we know 328 < 342.
Apply place value knowledge to solve real-world grouping problems (e.g., bundling items into hundreds, tens, and ones).
Example: If we have 287 pencils to bundle, we can make 2 bundles of 100, 8 bundles of 10, and have 7 single pencils left.
Explain your reasoning using accurate mathematical language (e.g., "The digit 4 in 456 represents 4 hundreds, or 400.").
