Subtracting with unknowns is a concept that takes some practice. Have your students practice whole group, independently, or as a class with the self checking task cards. They are great for centers or a whole class SCOOT.
Each card has a subtraction with missing minuend problem and a QR code with the answer embedded (no need for an internet connection!). Students can self check while they practice or they can check after they have finished all the assigned cards.
You can also use these cards as a SCOOT or QR Code Scavenger Hunt. Just have your kids grab a piece of paper, number it to 50 (or whatever number you want them to complete), and start working!! :)
This listing is for a PDF file that contains 50 task cards (color)
