Cut the pictures on pieces: the roof should be one piece and every line contained two number is one piece too. You can laminate the pieces to keep them safe.
Ask the pupils showing them the roof with the number on it: Who lives in this house/
Pupils should find all the bounding numbers which sum is the number on the roof.
Then they can construct the house and put the roof on it.
Pictures can be used for presenting number bounds on a board as well. In this case they should not be cut on pieces.
