Estimating Products
September 24, 2013 | Posted in: Homework Assignments, Learning Resources
Today, we worked on learning how to estimate products. This was the outcome of two big skills we’ve been focusing on: estimating numbers and multiplying extended facts. The kids did a wonderful job in class. Below, you will see the video we made together. What I forgot to mention in the video was:
When you round the numbers, IN THIS ACTIVITY, always round to the largest possible place value. For example, round 6,386 to 6,000 (nearest thousand) – not to 6,400 (nearest hundred) or 6,390 (nearest ten). Why? Well, suppose we were given the problem 6,386 x 5. I can use my extended multiplication skills to multiply 6,000 x 5. But we haven’t yet learned how to multiply 6,400 x 5. (We will!)
Did you stop by our website this afternoon/evening as I suggested? If so, reward yourself! Skip any three items, other than numbers 13 or 14 on pg. 48 or number 5 on pg. 24.
Here’s the video:
