The doubling rule worksheets
Each print is a different sheet with its own answer key. You don't need to sign up.
A short-vowel word ending in one vowel and one consonant doubles that consonant before an ending that starts with a vowel, like -ing or -ed: run becomes running, hop becomes hopped. X never doubles: fix becomes fixed, box becomes boxing.

Each print is a different sheet with its own answer key. You don't need to sign up.
When a short word ends in one vowel plus one consonant, that consonant doubles before -ing, -ed, or -er: run, running; hop, hopped; big, bigger. Second graders apply the rule and hear why: the double letter keeps the vowel short.

3rd grade
Third graders use the doubling rule automatically and handle the telling pairs where doubling changes the word entirely: hopped and hoped, tapped and taped, pinned and pined. Choosing by context shows the rule is about sound, not decoration.
