4.7 Verb Tense and Spelling: Past Tense Endings
downloadable past tense spelling worksheet
As you know, the regular way of forming the past tense of verbs in English is to add -ed to a verb root.
treat + -ed = treated
root + affix = past tense
Sometimes, however, the spelling changes when the past tense suffix is added.
1. Give the plural form of these words:
What is the rule of past tense spelling based on these words?
2. When we look at more data, we may need to add another rule. What is the past tense form of these words?
3. And when the word is only a single syllable, what is the past tense form?
4. And finally, what is the past tense form of these words?
Write a rule to explain the spelling pattern.
[Teacher Notes: for (1) VC + ed = VCCed, for (2) VC + ed and stress not on last syllable = VCed, for (3) VC + ed and one syllable = VCCed, and for (4) VVC + ed = VVCed.]
