Practice logical thinking: Kayden was directed to the block numbers opposite the road. He observed and verbalised from most right block "203, 204"... the next block was totally blocked by the trees... he said "I cannot see..." I acknowledged that and led him deeper about sequence numbers 3,4,5,6 and consistent patterns of numbers '20x- 20y- 20z'... in split moment, he burst out:" That block is 205! And next one is 206! Right mummy?" I praised and gave him the concept of same design of flats are called clusters and usually numbers are sequenced.
This is also part of survival skills in real world.
