  • I can use an algorithm to multiply a fraction and a fraction (i.e. ⅔ x ¾)
  • I can use a model to multiply a fraction and a whole number to illustrate how multiplying a fraction and a whole number represents finding multiple parts of a part.(i.e. ⅔ x 2 using a brownie pan model)
  • I can use an algorithm to multiply a fraction and whole number (i.e ⅔ x 2)
  • I can use a model to multiply a fraction and a mixed number to illustrate how multiplying a fraction and a mixed number represents finding a part of a whole and a parts of a part. (i.e. ⅔ x 2¾ using a brownie pan model)
  •  I can use the distributive property to multiply a fraction and a mixed number to illustrate how multiplying a fraction and a mixed number represents finding a part of a whole and a part of a part.  (i.e. ⅔ x 2¾ = ⅔ x 2 + ⅔ x ¾)
