This problem provides an opportunity for introducing and raising children's awareness of negative numbers. The first part of the problem is moving up and down a ladder or steps into a swimming pool. Students are counting along a number line, but in this case it is vertical rather than the more usual horizontal orientation. The final part of the activity encourages children to be creative and invent their own way of numbering the steps below the water level. The Teachers' Notes page offers suggestions for implementation and discussion as well as ideas for extension and support.
