Missing Part Task Cards: 1st Grade Common Core: Operations & Algebraic Thinking
This is a set of 24 QR code task cards aligned to the first grade common core standard:
CCSS.Math.Content.1.OA.D.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.

Students will need to determine which number is missing to complete the card.

The use of dots instead of numbers in the bottom half of the card allows for practice of subitizing, or quickly recognizing the number of objects in a group.

QR codes are included on each card so that students can check their work.
