Vertical and Horizontal Lines

Little-N has been working with line activities in the geometry curriculum. He has learnt about vertical and horizontal lines. 

A bowl of water with a floating stick  is used to demonstrate a horizontal line. A plumbers line was supposed to be used to demonstrate a vertical line. I didn't have a plumbers line, instead I used a padlock on the end of string [not clear in the picture but he got the idea].

Once Little-N was clear on the differences between vertical and horizontal lines, I gave him a load of his pictures to sort into vertical and horizontal pictures.
