Draw a circle design that would work for Han and a circle design that would not work.
Priya drew a design that has 6 circles, 3 triangles, and 3 squares. Would Han be able to color it the way he wants? Show your thinking using diagrams, symbols, or other representations. Use counters if it helps.
Activity 2 Card Sort: Even or Odd
