2. Let’s look at the number in a place value chart.Three-Digit NumbersStefan picks a number. His number is 346.What is each digit in the number ‘346’ worth?HundredsTensOnes346In the hundreds column, there is the digit ‘3’. This represents 3 hundreds or 300.In the tens column, there is the digit ‘4’. This represents 4 tens or 40.In the ones column, there is the digit ‘6’. This represents 6 ones or 6.Together, 300 (3 hundreds) + 40 (4 tens) + 6 (6 ones) make 346.346 = 300 + 40 + 6
3. Three-Digit Numbers346 can be represented using base ten blocks.There are 3 hundreds flats. This represents 3 hundreds or 300.There are 4 tens sticks. This represents 4 tens or 40.There are 6 ones cubes. This represents 6 ones or 6.Together, 300 (3 hundreds) + 40 (4 tens) + 6 (6 ones) make 346.346 = 300 + 40 + 6
4. Three-Digit Numbers346 can be represented using place value counters.100There are 3 hundreds counters. This represents 3 hundreds or 300.There are 4 tens counters. This represents 4 tens or 40.There are 6 ones counters. This represents 6 ones or 6.Together, 300 (3 hundreds) + 40 (4 tens) + 6 (6 ones) make 346.346 = 300 + 40 + 610010010010101010111111
5. Three-Digit NumbersLet’s look at the number in a place value chart.Let’s look at a different number.Mabel picks a number. Her number is 789. What is each digit in the number ‘789’ worth?In the hundreds column, there are 7 counters. This represents 7 hundredsor 700.In the tens column, there are 8 counters. This represents 8 tens or 80.In the ones column, there are 9 counters. This represents 9 ones or 9.Together, 700 (7 hundreds) + 80 (8 tens) + 9 (9 ones) make 789.789 = 700 + 80 + 9HundredsTensOnes
6. Three-Digit Numbers789 can be represented using base ten blocks.There are 7 hundreds flats. This represents 7 hundreds or 700.There are 8 tens sticks. This represents 8 tens or 80.There are 9 ones cubes. This represents 9 ones or 9.Together, 700 (7 hundreds) + 80 (8 tens) + 9 (9 ones) make 789.
7. Three-Digit Numbers789 can be represented using a part-whole model.700 is a part.80 is a part.9 is a part.Together, 700 (7 hundreds) + 80 (8 tens) + 9 (9 ones) make the whole 789.789 = 80 + 700 + 9789807009
