Phonics is of great importance in Year 1. We build on the phase 3 and 4 sounds taught in Year R, learning phase 5 and mastering blending with fluency. The children will be able to read both real words and made up words, adding sound buttons to identify the different sounds in the words.
I can't recommend watching Mr Thorne Does Phonics on YouTube highly enough. It will enable you to ensure your child is correctly saying the sounds as well as reinforcing their learning. For a fun, interactive website that echoes the games played in school to make learning fun I would suggest PhonicsPlay. Teach Your Monster To Read is another great site, as is Phonicsbloom.
