I have, who has-Robot Subtraction (10 Less)
Mentally subtracting 10 from a given number is Common Core Standard for First and Second Grade. "I Have, Who Has" is an easy to use game that is great for practicing subtracting 10 from another number. “Robot Subtraction” covers subtracting 10 from other two digit numbers. 28 subtraction fact cards are included.
The teacher simply prints, laminates, and cuts the cards then passes the cards out to students. Each student must listen for a subtraction fact that equals the first number on his card. Once a child hears the first number on his card, he is able to read his card aloud. My kids LOVE "I Have, Who Has." Directions for use and Common Core standards are included.
1.NBT.5. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
2.NBT.8. Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
This packet is CLASSROOM TESTED! My students use Number Grids when playing this game to help those students who require an extra resource.
