SMILE! You Can Subtract with QR CODES Common Core Aligned
This set includes 209 cards.
These cards include subtracting up to number 20.
Have students solve the subtraction problem and then check their answer using a QR CODE Reader- I usually use a free app
I would print these cards and have them laminated to use year after year.
This will keep students actively engaged and excited to learn about addition.
