Objective: Students will practice a variety of distribution-based strategies to multiply 2-digit numbers by 2-digit numbers, evaluating magnitude estimates using different adjusting techniques including rounding, and making sure each step of the multiplication process gets done when multiplying 2-digits by 2-digits.
- How did adding a 4th non-zero digit to our 2-digit factors impact the number of steps needed to find the product using distributive strategies?
- What are the pros and cons of using these strategies to multiply?
- How did adding a 4th digit impact the accuracy of estimates?
