How should I respond to this message? I like how you emphasize the importance of understanding key terms before diving into the concept of decimal place value. These foundational terms help students grasp more complex ideas. Your approach of connecting decimals to everyday experiences like purchasing items is a great way to make the topic more relevant and engaging for students.

I also appreciate how you distinguished between rational and irrational numbers. Students must understand how decimal expansions behave. When introducing irrational numbers like or 4, have you thought about using visual tools like number lines or calculators to help students see how these decimals don't repeat or terminate? It could provide a clearer distinction between rational and irrational numbers. What strategies would you consider for reinforcing the difference between these two types of numbers in your lessons?
