Document Summary

Use the space at right to solve 18 33 using the partial-products algorithm. Label each partial product with a capital letter (a, b, etc. ) b. On the grid below, outline an area to illustrate the multiplication problem above (i. e. , illustrate the problem with an area model of multiplication). Subdivide the area to show clearly where the partial products are seen in the algorithm above. Label the area corresponding to each partial product with the appropriate capital letter (a, b, etc. ) used in part a above. Write a string of equations that corresponds to the description for mentally solving 59 7 given below. Your string must begin with 59 7 = and conclude with = 413, as indicated in the outline below (you do not need to use all of the blanks, however. ) 6 times 7 is 42, so 60 times 7 is 420, then take away the extra 7 to get 413.
