I created these dog-themed timed math sheets to help meet the Common Core State Standards for subtraction fluency within 20 for second graders. In addition, feel free to used them for any child who isn't fluent with their facts yet.
This zip file includes 24 practice files including: 1s, 2s, 3s, 1-3s, 4s, 5s, 6s, 1-6s, 7s, 8s, 9s, 1-9s, 10s, 11, 12s, 1-12s, 13s, 14s, 15s, 1-15s, 16s-20s, and three versions of 1-20s.
Each fact sheet has 2 options for practice:
1. If you would like to time how long it takes them to complete
the whole page, use the first page.
2. If you would like to have them complete as many as possible
in a specific amount of time use the second page.
Each fact set comes with the two pages mentioned above and also comes with an answer key.
