10 questions
1st - 3rd Grade
English
The 1-1-1 doubling rule worksheet helps Grade 1–3 students decide when to double a word’s final consonant before adding a vowel suffix. Across 10 multiple-choice questions, students apply the rule to words such as run + ing, big + est, rob + er, swim + ing, and plan + ed, selecting the correctly spelled result. Students also distinguish one-syllable words with one vowel and one ending consonant from words ending in a two-consonant blend. Items such as walk + ing, test + ed, and whisk + ing reinforce when no doubling is needed, helping students explain and check spelling choices rather than memorize isolated examples. This English worksheet is a free printable resource with a complete answer key for classroom practice, review, or independent work.

This worksheet covers applying the 1-1-1 rule when adding vowel suffixes such as -ing, -est, -er, and -ed. Its 10 multiple-choice items ask students to choose whether to double the final consonant, as in running and biggest, or leave the base word unchanged, as in walking and tested.
Introduce the rule with a quick word sort: have students identify the syllable count, vowel pattern, and ending consonant in examples such as run and walk. Then model one multiple-choice item at a time, asking students to explain why running doubles the final consonant while walking does not before they complete the remaining suffix examples independently.
Students may double the final consonant automatically whenever they see -ing or -ed, producing errors such as walkking or testted. They may also omit doubling in one-syllable, one-vowel, one-ending-consonant words, choosing runing or bigest instead of running or biggest; remind them to check the base word’s ending pattern first.
