Today, Arianna and I continued to work with understanding decimals. She related decimals and fractions in words and found decimals to the tenths on number lines as well as whole numbers and decimals to the tenths. Then, we reviewed how to use mental math to multiply 2-digit numbers by multiples of 10 and 100. Finally, we began a lesson on multiplying 2-digit by 2-digit numbers which we will continue working on this week.
