Polysemic words

Now, childrem, a fun exercise to remember: 

               Two= quantity of a pair, not a polysemic word, e.g. I´ve got two eyes.

                 Polysemic words: To= 1) direction (to school, to London); 2) infinitive ( I want to sing),   

                         Too= 1).also, the same as...eg. You go and I will go,too. 

                                             = 2) an excesive quantity: It´s too big, too much/many, too tall.
