## Unit I: Place Value and Number Sense

September 16, 2016

I get to meet and work with some pretty amazing mathematicians everyday. Our first unit of study is always 'Place Value.' Why? When digits and symbols first came into existence to represent values, and the idea of a base-ten system was formed, mathematics became a language. The Rosetta Stone of math then, is place value. It is as important to the understanding of all of those calculations, algorithms, graphs, postulates, formulas, theorems, and properties, as a foundation is to the the tallest building on Earth. If there are holes in your child's number sense/place value foundation, it is hard for us to build upon their learning.
