Lesson 15 Learning Objectives:
Estimate, measure, and compare measurements in meters and centimeters
Develop a sense of 1km and the relationship between kilometers and meters by comparing distances based on the magnitude of numbers up to 10 000
Solve problems involving distances in kilometers
Math Talk:
See Math Talk image below
Meter stick
(turn a stick into a meter stick and play with measuring. You might also find one at a thrift store!)
Polypad: measuring tools
(how can you convert cm to m?)
Reflect:
Reflect in your math journal. Draw, create or write to share your thinking. See Lesson guide 15 for more reflection questions, real life anchoring, playful explorations and creative invitations.
How do you know when to measure in meters or kilometers?
What number patterns do you notice between m and km?
How does measuring distance help us understand how we move through the world?
Math Talk:
Have a conversation about this image. Be curious. Be creative. Can you see in different ways?
What do you notice? What do these distances tell you? How far does 1000km feel? 10000km?
