I taught my kids to read before they could talk, they knew well over 50 words which they could identify by pointing to whatever the word was when they saw the word.

I was lucky enough to pick up the book - Teach your baby to read
for about 50 cents at a council book selloff. The system in the book uses flash cards with words like hand, foot, nose etc and you just show them to the kids and say what the word is while touching that body part.

I also taught them maths in a similar manner and they were proficient in algebra by the age of 5. For the algebra I used pictures of fruit for abstract representations of quantities. They just soaked it up like sponges.

Apparently that system system of reading doesn't work for older kids but it works really well for babies. Now my kids are in the top 5% of the country on NAPLAN tests. School is a breeze for them & they are miles ahead of their peers.

Teaching them to read before they could talk was one of the best things I ever did for them.
