Subtraction Within 20 Drill Sheets | 150 Facts From 20 to 11 | 1st Grade Math Fluency

Ribbit — ESL/EFL Worksheet Resource

This 10-page set of subtraction drills gives 1st grade and kindergarten learners 150 vertical subtraction facts where the first number is always between 11 and 20. Each page has 15 numbered sums, such as 20 − 4, 17 − 3 and 13 − 1, with a small cartoon sea creature or animal in the corner. The numbers taken away run from 0 to 9, so every answer stays in the teens or high single digits and children never have to regroup across a ten. That makes these sheets a step between subtraction to 10 and full subtraction within 20. There's no answer key, and the pages are all black and white.
