Matching the new common core this is a complete unit for teaching the memorization of subtraction facts addend by addend. It can be used in kindergarten common core "fluently subtracts from 5", in 1st grade "fluently subtracts from 10" or in 2nd grade "fluently subtracts from 20".
Starting with -0, each section includes flashcards & 2 practice tests to send home for homework. Then 2 practice tests and a final test for during class. Each test has 20 problems to be completed in 2 minutes.
Sections include -0, -All, -1, -2, -3 (These include up to 12), Doubles Facts, Tens Facts, -4, -5, -6, -7, -8, -9, & -10 (these subtract from higher numbers).
Flashcards can also be printed off for during class use. You could have an older grade come to practice and drill with the flashcards. You could also leave flashcards at a center or station for independent practice.
This is a unit that can be used after the addition fact unit is completed or even for student who have already mastered all their addition facts.
Memorization is the best option for fluency! I hope you find this unit as useful as we do!
