Learning the letter sounds
In Jolly Phonics the 42 main sounds of English are taught, not just the alphabet. The sounds are in seven groups. In synthetic phonics some sounds are written with two letters, such as ee and or. These are called digraphs. Note that oo and th can make two different sounds, as in book and moon, that and three. To distinguish between the two sounds, these digraphs are represented in two forms. This is shown below.
