This is a fun math project for first through fourth grades. Everything you need is included in this booklet. The project is based on the story of David and Goliath, one of the most popular stories in the Bible, recorded in the 17th chapter of the book of First Samuel. Even people who know very little about the Bible, are familiar with this story. The key element in the story is how a small shepherd boy who trusts God is able to defeat a huge giant that everyone else is afraid of.
The lesson is all about measuring and comparing heights. In order to make the comparisons, the students will create a life-size drawing of Goliath. The drawing of Goliath can be created two ways.
1. The small drawing in this lesson booklet may be projected and traced onto paper taped to a wall.
2. Pages are included which can be printed and then taped together and colored to construct the life-size image.
First, compare the heights visually. It’s fun to photograph the students next to the drawing as they play the part of David.
Then compare the heights using math. One way is to calculate the difference between their heights and Goliath's. For students who understand ratio fractions, they can create ratios. For students who understand percent, they may use that method.
Most versions of the Bible give Goliath’s height written in cubits and spans. Students can learn how to use these ancient measurements for their own heights (optional).
