(Notice the pretty sheep painting on the front- that's a copy of an original painting that my sister did for M's sheep-themed nursery)
I just know you'll want to take a look at this book my mom made and sent to M recently!
Each page has a different letter for M to look for and point out as it appears in lots of different words. M is at just the right stage to be able to be successful at this skill and to enjoy it.
At the end of the book there is a section for M to point to the word that starts with a particular letter. This skill still confuses her, but it's good to have something challenging there too; I've seen plenty of times how we'll go over and over something that seems to totally go over her head, but then one day it just "clicks!"
