Rhyming-we will get it?

We have been working hard on rhyming words!  This concept seems to be a struggle this year.  I have been working on it in small group and during whole group.  The kids think that rhyming words need to start with the same letter.  We are working on listening to the ending of the word to see if it sounds the same.  Please help at home with rhyming words!  We are starting to get it, it is just taking its time this year!
