How to respond back to this message? You did a great job on your post. Breaking down each place value and telling exactly what each number to the right of the decimal represents, like 1/10 or 1/100. This can be very helpful in explaining this concept to anyone who has no prior knowledge of it. A good way to teach this is using money to purchase items. If your total is 14.10 you would know that the .10 is equal to 10/100. They could see that ten .10 equals one whole dollar. Using play money or money you make on your own could be a helpful tool in teaching this!
