📚 Topic Summary
Base ten blocks are a fantastic way to visualize subtraction! Think of them as physical representations of numbers. When you subtract, you're essentially taking away blocks from the larger number. If you don't have enough ones to subtract, you'll need to regroup (or borrow) a ten into ten ones. This makes subtraction easier to understand and solve. Ready to practice?
