This exercise is a laboratory method of training how the numbers are built up, in this case number 5. Distribute one fence and five animals to each pair of children. Then have the children to think about how many different ways the animals can graze in Bosse the farmers’ two pastures.
If you want to extend the exercise you can have more pastures than two for the animals to graze in and have even more animals than five that are out grazing.
Material: Animals, fences (fences no need, two books can act as two different pastures)

Thank you Nina for the idea from the blog Räkna med mig.

There have been some experiments with floating here. I’ll give you one more. Then I have something else up my sleave.
