Should I introduce my 2 y.o. son to basic math? He really loves numbers. He can count to 100 and knows up to a billion (reading the numbers and knowing what the placements mean). This was the result of a very interesting place mat he got as a gift and nursery rhymes and songs I guess. He recognizes numbers in any random order and reads them everywhere. Street numbers, license plates, etc... He understands that 40 represents 40 of something, etc... He can count, but now he can just look and something and tell me how many (12 or less). So do I show him that 1+1=2? I have a feeling he may already inherently know this. Sometimes I am amazed at what he already knows.
