Teaching Exponents. We have been busy in math working on exponents! I have an accelerated 5th grade group, so we needed to cover 5th and 6th grade standards on exponents. We haven't quite gotten to evaluating expressions with them yet, but they are exponent pros now! Here are the two anchor charts we made, and the students also put these into their math journals.
As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number of places to the right. A negative exponent shows that the decimal point is shifted that number of places to the left. In scientific notation, the digit term indicates the number of significant figures in the number. The exponential term only places the decimal point.
