Dyslexic adult here. Apologies for any spelling or grammar errors in my post.
Be patient with your child.
I wasn't diagnosed until 18 and half way through a levels. I just thought I was stupid and slow.
Try different coloured paper and font. I can't read red or purple but any other colour font is fine. I like yellow paper to read off.
Don't discount television for learning words and numbers. Loads of BBC programs available.
If your child has slow progressing then repetition is your friend.
Don't get frustrated. I remember my parents frustration and it still bothers me.
Use props and objects.
Use an abacus or tokens for counting to help your child visually.
Show your child what the word is for example the earth show him the earth watch space programs. Give context.
Make it fun. If it's fun it's easier and you and your child want to participate.
Use your child's interest. If your child likes flamingos then use flamingos.
Get creative.
Reward reward reward. It's hard for you both.
Education is better for dyslexic kids and the work place is better for dyslexic employees.
Everyone has a place. It's just a case of finding that place.
Find something your child is good at. Do that thing a lot so they feel successful it will boost confidence.
PM me if you would like to talk.
Best of luck
