If some (or all) of your students are ready to work with negative exponents, check out Multiplying by Powers of 10 Task Cards by Hello Learning.
And for those students who are up to an even greater challenge, grab this Negatives with Exponents Dolphin Coloring Picture, created by Briana Burke.
As a teacher of fifth grade math, I can see how all of these products would work together beautifully to really reach all of my students in their study of exponents. It's time for a shopping spree!
