I received some inspiration yesterday from one of my favorite preschools that had their students come up with ideas from materials ready for recycling. Children chose from cardboard boxes, glass jars, shredded paper, wrapping paper scraps and strawberry containers. They were then told that leprechauns love shiny, sparkly things, so children eagerly decorated their traps with vigor.
Try to have your child visualize what a trap may look like. What will lure the leprechaun inside? Where will the leprechaun enter? How will it get trapped?
Here is a simple trap made from a plastic container with a lid and a paper towel tube. Nothing too fancy (it was done by a 3 year old). I guess leprechauns love potatoes, so one was put inside so the little bearded creature could smell it via the "tunnel".
An abstract idea that can be carried out for a day or two is excellent to keep children connected to a single idea and to work on delayed gratification. Be sure to let your child know that leprechauns are very tricky and mischievous. I say something along the lines of, "I have tried for years to catch one, and I never have. We can try... but those leprechauns always find a way out."
I'm sure your child will come up with a ton of questions for you to creatively answer.
The leprechauns in my house come at night when everyone is sleeping. They like to play with toys and then leave a mess to let you know how mischievous they can be. Leprechauns also leave behind gold glitter wherever they walk.
Get as creative as you like... your kids will eat it up.
