Base 10 Blocks Subtraction Concepts

Teacher Mike guides students through a series of subtraction problems using base 10 blocks. Each problem involves identifying the number of tens and ones, determining how many blocks are crossed out, and verifying the correct subtraction sentence. The video covers five problems, each with a different starting number and amount to subtract. The tutorial emphasizes understanding place value and checking work by comparing answer choices.
