Number - Block Number

Started this year J has suddenly like to see and remember the unit number of the shops at Yew Tee Point. Everyday he would try to get Daddy to Yew Tee Point to see the unit number. Till now he has remembered all the unit number for each different shops (or at least 90%) in Yew Tee Point and also the unit number of the shops in our estates.
Whenever we go Lot 1 or other shopping area, he would ask to go to the directory.
I took the below pic, hoping that he will look at the pic instead of going there!








I think he has reverted to his old habit of looking at block numbers again.
See, he uses Poster colour for the past 3 nites writing the block numbers.
He said he dunno how to write, insisting on us holding his hand to write but he dictate what block number to write.
