Chameleon Prefixes: IN- to IM- Assimilated Prefixes Spelling Activities
$3.50
If your students misspell words like impossible or impatient, this resource gives them an easy rule, repeated practice, and meaningful reading opportunities—so spelling becomes predictable instead of random.
Description
Some prefixes are “chameleons”—they change or assimilate their spelling to make words easier to say. This Chameleon Prefixes Set 1 focuses on the most common spelling shift students see in upper elementary and middle school:
✅ in- → im- (before m, p, b)
