I'm not sure about your kids but I know my upperclassman still love to color! They can't wait to get their hands on a coloring page even if they have to do math first!
This Color By Number features Annuities where students will need to find the present value and future value of various equations. As well, they will have to solve for monthly payments. Lastly, the last few questions are a bit more rigorous and require a bit more thought featuring annuities within an annuity and logarithms.
Please have students show work on a separate sheet of paper!
