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.
If a pyramid has a pentagon base, how many triangle faces does it have? How do you know?
Why do all pyramids, no matter the base, come to a point at the top?
Why do you think pyramids are named after their bases, not their peaks?
How does a pyramid change when the base has more sides? Does it feel taller, wider, heavier?
What would it be like if your home/room was shaped like a pyramid? How would you decorate? Where would you sleep?
Math Talk:
Have a conversation about this image. Be curious. Be creative. Can you see in different ways?
What do you notice? What shapes do you see? What shapes make shapes?
