Anthony and Olivia want to use area
to find six times 14. Olivia splits this rectangle in
half, but she can’t finish because she doesn’t know what six times seven is. Anthony says it’s easier to use the
10 times table. How would he split the
rectangle?

When Olivia split the rectangle in
half she took the length of 14 and divided it into two parts, each measuring
seven. To find the area, she would then
need to multiply six times seven and six times seven and then add them together. If Anthony wants to use the 10
times table, he would need to divide the 14 up into 10 and four. We see this in the first example:
10 and four equals 14. There’s nothing wrong with breaking
the rectangle up into eight and six, but Anthony wants to use the 10 times
table. And that means he would need to use
a 10.

Now that we’ve selected Anthony’s
image, we need to pick the next step in his calculation. Remember to find six times 14,
we’re finding two smaller areas and then adding them together. Anthony is using the 10 times
table, which means he’ll have a piece that is six times 10 and the smaller piece is
six times four. That means his next step is to find
the six times 10 plus six times four. Finally, we need to add the areas
of the two parts to figure out six times 14. Six times 10 equals 60. Six times four equals 24. And 60 plus 24 equals 84. What we’ve found is that six times
14 equals 84.
