What does the One More, One Fewer worksheet cover?

It practises the effect of removing one as well as adding one — 5 questions for Kindergarten, all on Common Core K.CC.C.6: Look at two groups and say which has more, fewer, or the same. The instruction to pupils is “How many would there be with one fewer?”, and the answer key follows on the next sheet.

Which Common Core standard does One More, One Fewer practise?

CCSS.MATH.CONTENT.K.CC.C.6 — K.CC.C.6, in the Counting & Cardinality domain for Kindergarten.
