I was thinking that minimal pairs (at least the ones that contrast initial sounds) will always inherently rhyme. Rhyming is a basic phonemic awareness skill often targeted at the preschool level. Minimal pairs are also easily found in the lists of word families taught to early readers.
Whether you're working on speech, phonemic awareness skills (as part of speech or as part of pre-reading skills), or word families (as a reading or spelling exercise), picture sets organized in this fashion are useful.
And so here are some sets. I made one for -an, -ake, and -ace. I hope someone finds them to be useful. I intend to use them for final /k/ and final /s/ practice as part of our speech program and as practice in reading word families for Michael.
