Each child has a partner and each pair of partners is numbered.
The partners sit opposite each other with their legs stretched out with both feet touching. All the groups sit next to each other to form a ladder. The leader calls out a number and the partners have to run through the ladder. The idea is to see who can get back to their spots first.
If you have an odd number of children then have the leader to join in.
Try saying several words at once.
Team up the left vs. right side of partners (when looking at the ladder from the end as shown above) and have them race off one set of partners at a time. The team to get the most of their side of partners to complete the ladders game faster than the other side wins.
