  1. 5 cookies
  2. Encourage students to work in pairs to find all the possible partitions of 10.

    0 for Grace and 10 for Ana

    1 for Grace and 9 for Ana

    2 for Grace and 8 for Ana

    3 for Grace and 7 for Ana

    4 for Grace and 6 for Ana

    6 for Grace and 4 for Ana

    7 for Grace and 3 for Ana

    8 for Grace and 2 for Ana

    9 for Grace and 1 for Ana

    10 for Grace and 0 for Ana

    Students' methods will vary. Organize their answers using a table or number sentences so they can see that Ana has all the numbers of cookies from 0 to 10 and Grace does too. Draw attention to the use of the turn-around facts in Question B, e.g., 7 + 3 = 10 and 3 + 7 = 10

AA. Sharing Cookies

  1. Ana has 10 cookies to share with her friend Grace. If each girl gets a fair share, how many cookies will each girl have?
  2. List all the other ways (the "unfair" ways) Ana could share her 10 cookies.
