## Reflection: Real World Applications Estimation: Putting rounding skills in action using real life examples. - Section 2: Core Lesson

How does this real life topic transfer into estimating a standard algorithm? It is this idea that is an example of practicing MP2 as we make sense of quantities and use that to achieve a mathematical goal. We need to have mastered 4.NBT.A.3 fairly well first to understand this. The population connection to our state helped master the standard because the multi-digit number is useful to manipulate to round and estimate, and it is a personal connection that helps them understand the growth of our state.
