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.
In a fractional exponent, the numerator is the power to which the number should be taken and the denominator is the root which should be taken. For example, 125 means take 125 to the fourth power and take the cube root of the result or take the cube root of 125 and then take the result to the fourth power.. Order does not matter when evaluating exponents--it is usually easier to take the root first, and then take the power.
