run --> running

swim --> swimming

skip --> skipped

To teach my students the rule for doubling the final consonant, I made this flow chart:

This phonics lesson goes great with these little characters

(my students where so happy to see these guys again)!

You can purchase these cute letter characters and a whole unit of word ending practice at my TpT store.
