This is a great practice or assessment product to use after students have learned to recognize even and odd numbers. There are 24 task cards that can be used with or without QR codes and 24 cards for SCOOT/assessment. There is also an answer key for the task cards and a worksheet students can use to write their answers for the SCOOT activity. Just print and laminate and they are ready to use. You can probably use these for first graders during the second semester. It"s great for second graders and some third graders would benefit as well.
