How to Trap a Leprechaun!Posted by Carlene Gordon
Leprechauns are greedy and sneaky and love shenanigans! So how do you trap one? Fourth graders know, you employ math and engineering skills!
After reading about a mischievous leprechaun in the book Leprechaun Trap by Adam Wallace grade four students went to work to create an efficient but also cost-effective trap. Students discovered that to be successful, they had to think like a leprechaun. Character traits from the story were identified as the students designed and redesigned. We discussed the field of engineering materials and items were carefully chosen not only for their utility, but also with a eye on the cost effectiveness. Each material they chose to use in their design had a price attached. Once completed, students added to find the cost and worked with decimals (our next unit in math!) to give a final cost analysis. In the end, our students presented and demonstrated their projects and the thinking that brought them to their final design. Even Mr. R-M couldn’t resist getting in on the fun!
