My class loves practicing math facts with QR Codes! QR (Quick Response) codes can be scanned with any device that has the scan app downloaded.
Students write their differences on the coordinating numbered box on the recording sheet. A variety of recording sheet sizes are provided.
Next, students self check by scanning the QR code on each problem. Students should check their coordinating scanned answer with their recording sheet.

This product is aligned to the common core standards:
1.OA.6. Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
2.OA.2 Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
