Beginning blend sounds are different than digraphs and can be tricky for beginning readers to learn. I love finding extra printables and helps that are different than our normal homeschool reading curriculum.
I love these blend books from 123 Homeschool 4 Me. They are color and trace blend books that cover s, r, l and tw blends. You can use these as a great learning tool and turn them into a game as well. Your children will be able trace the letters, say the words and work on their blends as they are coloring and putting their booklets together.
You can get the detailed directions on how to use these blend booklets and the free printables HERE.
