Cindy Aossey and Dee Crescitelli started the session with a notice and wonder about two graphs.

MoMath Area and Perimeter Puzzle

From MoMath Mindbenders for the Quarantined

Cindy started the meeting by asking participants to draw rectangles in Jamboard using the graph paper background.

Egyptian Fractions

The session started with an example of Egyptian representations of whole numbers.

Number Visuals

The session opened with a wonder and notice of this image:

Participants noticed that the number of dots in each figure is increasing by one as you look left to right in each row. One person said they see certain groupings of dots repeated in other groupings. Another noticed that the dots are arranged in a circle for some numbers and someone else wondered if that was because those numbers are prime.
