Effective and easy to use, these three worksheets give focused practice for capital letters with only one rule to follow:
(1) when naming a particular person, place or thing.
This applies to about 99% of what students will need to know when writing, so there is no need to make the grammar skill of capitalization more tortuous than necessary, especially for beginning English or struggling students. Of course, a capital letter at the beginning of a sentence is usually obvious, and not included here.
Grammar practice does not have to be complicated.
