Teachers, save “Measurement Challenge: Big, Blue Whale” to assign it to your class.

Think like a mathematician to solve the problem: What objects can you use to measure a big, blue whale? What do you think your measurement will be? For example, "I can use a school bus to measure the whale. It will probably be 3 busses long." 1. Tap to watch the video. 2. Tap to draw a picture showing how you would measure the whale. 3. Tap to record a video of your explanation. Feel free to be as creative as you would like. 4. Tap when you're done.
