Reflection: Adjustments to Practice Estimation of Products Using 1 Digit up to 4 Digit Equations. - Section 2: The Core Lesson: Understanding the "how" for now with connection to the "why".


With the Educreations quick review, this all tied up into a very neat package for mastery, skill work and in depth understanding of multiplying by 10s in estimation and the Associative Property. My new thinking is that if we want them to use estimation in the real world and if they have mastered understanding of place value's role in multiplication, estimating products should be a snap! It's good to start with simple numbers. My below grade level achieving students should feel more accomplished because they will soon understand completely why they need to round one multi-digit number and why they don't need to consider rounding the one digit factor they are multiplying.
