Diana, age 2.5, uses Education Cubes to drill her short vowel sounds.
She tosses the cube...
...and says the sound of the vowel that lands on top.
This is a lot more fun for her than repeatedly pointing to the letters in a book. She knows these sounds quite well now. This makes a quick review every few days to keep them fresh for her. She knows all the consonant sounds, as well, but has not yet caught on to the blending of the two sounds together.
