About Adding Endings

What this skill is

Adding inflectional suffixes requires applying orthographic rules: dropping silent e (hope -> hoping), doubling final consonants after short vowels (hop -> hopping), and changing y to i (happy -> happier).

When children learn it

Taught and mastered in 2nd and 3rd grade spelling conventions (CCSS 2.L.2.d, 3.L.2.e).

Teaching Tips

  • Teach the "1-1-1 Rule" for doubling: if a word has 1 syllable, 1 short vowel, and ends in 1 consonant (like HOP), DOUBLE the last letter before adding -ed or -ing (HOPPING). If not, don't double!

Common Mistakes

  • Doubling consonants after long vowels (writing "hopp" for hope + ing).
  • Not doubling consonants on short vowel words (writing "runing" instead of "running").
  • Forgetting to drop silent e before vowel suffixes (writing "makeing" instead of "making").
