PhonicsPlay has lots of Phonics game that your children can access to help with their reading/blending skills. Whilst schools are not open for all children you can access their resources for free at home:
However you can access lots of the games without having to log in at all! Just go to the phase you want to play at and you can see which games you can play without logging in.
Some of the games that we like to play at school are buried treasure and picnic on pluto. These games encourage your child to blend the sounds and then discuss the word that they have read - is it a real word? It's another way for you to bring Phonics into your home learning and build vocabulary, with the discussion around what words mean!
You could start at phase 2/3 and adapt the phase depending on what you feel your child needs!
