How could you sort these pictures into two groups? Be prepared to share your reasoning.
What are some characteristics that all circles have in common?
Select one of the pictures of a circular object. What are some ways you could measure the actual size of your circle?
On January 3rd, Earth is 147,500,000 kilometers away from the Sun. On July 4th, Earth is 152,500,000 kilometers away from the Sun. The Sun has a radius of about 865,000 kilometers.
Could Earth’s orbit be a circle with some point in the Sun as its center? Explain your reasoning.
Priya, Han, and Mai each measured one of the circular objects from earlier.
Priya says that the bike wheel is 24 inches.
Han says that the yo-yo trick is 24 inches.
Mai says that the glow necklace is 24 inches.
Do you think that all these circles are the same size?
What part of the circle did each person measure? Explain your reasoning.
