This GOOGLE FORM resource contains digital task cards with subtraction problems. I did not set this up as a multiple choice quiz but rather one where they have to type the correct answer. There are 12 problems to complete. This makes an excellent formative assessment!
You do not need Google Classroom to use this resource! The link provided in this product will enable you access to the google form. Then you can give your students the link or embed code to the google form to fill out. This is set up as a self-checking quiz. Students will be able to see how many questions they missed.
