How Tall Is My Giraffe? Exploring Measurement

giraffe-cartoon_clipart_image_16A very interesting math lesson stemmed from a story I read toCyan Magenta Yellow Black my students about a king who got a giraffe as a birthday gift. The king challenged his townspeople, offering a reward to the first person who would be able to tell him how tall his giraffe was. The people set off to measure the giraffe in whichever way they could – none of the attempts were successful. Every failed try served as a great lesson about measurement do’s and don’t’s.

How Tall is My Giraffe?

IMG_20150303_111305After extracting important math concepts from this adventurous story, I introduced students to a giraffe of my own (my children’s old plush growth chart). I posed the same question to an eager-looking bunch (there was no gold incentive on my end though). With just enough direction, I let students explore solutions to this problem during Learning Centres time. Students showed remarkable interest in this challenge and began gathering all kinds of objects to use as measurement tools.

How could I say no to that? After a few chuckles and excited cheers, we sat IMG_20150303_125631down to reflect on our findings, which ultimately led to another great inquiry question? Why did we need so many cotton balls yet such few blocks? How does the size of the measuring tool affect the measurement?
