Are you using Engage NY or Eureka math? Here are some great quizzes for you. I have written the Topic quizzes for 6th grade Module 2. There are 4 quizzes, one for each topic A to D. These are aligned to SBAC and use the Smarter Balanced Item Specs.
You will get great data and information about which of your kids need a little more help in learning about operations with fractions and decimals.
The file is a Word document and you are free to edit and make necessary changes to teach your precious children. You could also make multiple versions if you wish.
Happy Math, Megan
Note: This file also has problems from 4.OA.4, 5.NBT.6, and 5.NF.1 as they are relevant to these standards and this module.
