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.
To check for understanding, present the following to students: 1  For the sequence 3, 12, 48, 192, â¦, ask students to: Find the next term. Write a recursive rule. 2  Give the recursive rule An= -5An â 1, where the first term is 3. Ask students to: Write out the first 4 terms in the sequence. Express each term using exponents. If students are still having trouble, ask them what their questions are and model an additional example like each of the previous two.
