I made the rubric small so my students can slip it into their dry erase pouches. Feel free to make it larger if you don't have small pouches and slip them in sheet protectors.
We are also learning multiplication of whole numbers and decimals so this is also cross-curriculum by having them find the average by multiplying the total points times 6.25 to find the percentage.
If your students aren't ready to multiply by decimals hand out calculators and have them practice that skill as well. It's never to early to learn how to use a calculator.
