Students track the spelling changes that occur when forming contractions. Explain to students that making contractions is much like solving an equation. Write did and not on the board. Ask: How can these two words be made into one word? Lead students to understand that one letter must be taken away and an apostrophe added to make the contraction didn’t.
Have students use this organizer to explore how the spelling of a word changes when an ending is added, such as a plural ending (bunny/bunnies, wolf/wolves), verb ending (fly/flies, run/running, make/making), or suffix (happy/happily/happiness, explode/explosion).
