Renaming 3-Digit Numbers Creatively
Year 2 Mathematics WALT: Rename 3-digit numbers in different ways Using hundreds, tens, and ones
Warm-Up: How Many Tens?
Listen to the number Count the tens Write your answer on whiteboard 324 → ? tens 406 → ? tens + ? ones 250 → ? tens
I DO: Teacher Models Renaming 324
Standard way: 3H + 2T + 4O Creative ways: 2H + 12T + 4O 1H + 22T + 4O 0H + 32T + 4O 3H + 1T + 14O
Teacher Think Aloud
I have a 2-digit number with: 4 tens and 13 ones What is my number? How can I work this out?
WE DO: Let's Rename Together
Work together to rename: 506 718 430 242 Discussion: Which way is easiest? Can you prove they're all equal?
YOU DO: Independent Practice
Rename each number in at least 2 ways: 382 405 629 710 Challenge: I made a number with 1H + 12T + 5O. What is it?
Hands-On Exploration
Use MAB blocks or bundling sticks to: Build a 3-digit number Break hundreds into tens Break tens into ones Record all the ways to rename your number
Reflection Time
'Renaming helps me because...' 'The most interesting renaming I made was...' 'I understand trading hundreds and tens' 'I need more help with zero digits'
