Place Value is a "hit or miss" kind of concept for some children. They are either ready or not ready to take on this concept. I have found a really easy and quick way that probably isn't far from what all teachers start with and that is "houses". We all live in some type of house although it may appear different on the outside, it is where we live. I teach my children that numbers live in houses just like we do and when we move to a new house our address changes just like numbers do.
The concept of tens and ones is the foundational basis for our numeric system; students should be exposed to the idea of bundling 10 ones immediately. Students must be familiar with and demonstrate their knowledge of this basic premise that a one-digit number indicates the number of ones, while a two-digit number indicates the number of tens and ones. The idea that each digit in a number has a specific value is key to moving fluently through math. Here is the standard listed below:
1.NBT.2 Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
|-||10 can be thought of as a bundle of ten ones — called a “ten.”|
|-||The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.|
|-||The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).|
