Phonics is a huge part of Year 1 and we sit the yearly Phonics screening test. Revising digraphs and letter sounds will always support your child's decoding of new words and their reading and writing.
These 2 games support the blending of real and nonsense words. Nonsense words are part of the screening test in that they are unfamiliar and really test the children's ability to blend. Please note that identifying real and nonsense is only part of the game/fun but not part of the screening test.
