Multiplication by 10, 100, 1000

Main part:
One pupils dresses up as a witch. We explain that whatever the red magic wand touches multiplies it 10 times , and whatever the yellow wand touches divides it by 10, it becomes 10 times smaller.

Alternatively the teacher asks questions such as: if the witch touches a 3 cm worm how long will it become? If the witch touches a 300 kg giant 3 times, how much weight will he gain(or lose)?

At the end of the activity the pupils are divided into 2 groups and each group asks questions like those using the red or the yellow wands.
