a. Use the partial-products and standard algorithms to calculate 27 x 28. b. On graph paper, draw an array for 27 × 28. If graph paper is not available, then draw a rectangle to represent the array rather than drawing 27 rows with 28 items in each row. Subdivide the array in a natural way so that the parts of the array correspond to the steps in the partial-products algorithm. c. On the array that drew for part (b), show the you parts that correspond to the steps of the standard algorithm. d. Solve 27 X 28 by writing equations that use expanded forms and the distributive property. Relate your equations to the steps in the partial- products algorithm.

a. Use the partial-products and standard
algorithms to calculate 27 X 28.
b. On graph paper, draw an array for 27 X 28. If
graph paper is not available, then draw a
rectangle to represent the array rather than
drawing 27 rows with 28 items in each row.
Subdivide the
array
in a natural way so that the
parts of the array correspond to the steps in the
partial-products algorithm.
c. On the array that you drew for part (b), show the
parts that correspond to the steps of the standard
algorithm.
d. Solve 27 X 28 by writing equations that use
expanded forms and the distributive property.
Relate your equations to the steps in the partial-
products algorithm.
