## Reflection: Intervention and Extension Estimation: Putting rounding skills in action using real life examples. - Section 4: Independent Practice

Differentiating the independent practice helped me decide the levels of mastery of the standard, and then adjust learning levels as needed. Some kids catch on really fast after a hands-on learning experience.

If the below grade level students can easily round and estimate the addends in three place values, I increased the dice as they master the skill. I do the same  for the Middle Students. When High Students were finished, they can chose to do a short video on their iPad explaining when they think they may use estimation and why.  What I discovered was that my low students are still struggling with rounding. The extra process of having to add was difficult and some resorted to adding the exact number and rounding the sum.

Getting kids to independently practice using the dice game is a great way to get them to think about several things at once: What is the largest number I can create with these dice? What is the lead number to round? And, does my answer make reasonable sense? This supports MP1 in making sense of math and exercising their critical thinking skills in application.

Students that cannot line numbers up well, even with hundreds place numbers, find direction and organization in the graph paper. They can then skip a box and round the numbers right across from the exact number, line up the addends in a standard algorithm and easily and neatly add.

I liked connecting my Smart Board Lessons together as I teach estimation. It helps kids see how their learning builds up to another skill while using a connection to real life. This shows that CCSS MP4 is part of our math learning by using real life models to connect our math.
