Miss Turner demonstrates how to subtract three-digit numbers with regrouping using base 10 blocks. She starts by setting up the problem 321 minus 147, showing how to compose the number 321 with base 10 blocks. She explains the process of regrouping from tens to ones to subtract the ones place, and then from hundreds to tens to subtract the tens place. Finally, she verifies the result using the standard algorithm, ensuring students understand both the manipulative and algorithmic approaches to subtraction.
