Reflect:
*Reflect in your math journal. Draw, create or write to share your thinking. See Lesson 1 plan for more reflection questions, real life anchoring, playful explorations and creative invitations.

What’s the difference between how big something is and how much it can hold?
If two objects have the same volume, do they always look the same? Why or why not? Explain using real or imagined examples.
When you look at a flat picture of a 3D object, what clues tell you about its shape?
If 1 mL is about one drop of water, how many drops do you think make a full glass? A bottle? A liter? A bucket? How do you know?

Math Talk:

Have a conversation about this image. Be curious. Be creative. Can you see in different ways?

What do you notice? How does volume make sense to you?
