If you have a laptop this is a great PowerPoint to help support oral blending- this is when children can blend the sounds to make a word, eg c-a-t cat. It is vital that children have this skill before reading.
why don’t you find some objects around the house and see if your child can hear the sounds in the words such as pan P-a-n. Pen p-e-n ect
When we begin to teach letter sounds we begin with the letters s,a,t,p,I,n.
