Find the missing numbers. Two times three equals what, two
times six equals what, three times three equals what, and three times six equals
The model shows an array of
doughnuts. Each column in the array contains
three doughnuts. Each row contains six
doughnuts. We can use the array to help us
multiply. First, we need to calculate two
times three, one group of three, two groups of three. Two groups of three, how many
doughnuts do we have all together? Three and three more is four, five,
six. Two times three equals six.
Next, we need to find two times
six. We know that each row in the array
contains six doughnuts. So, how many doughnuts are there in
two rows of six? We can start counting at six
because we know there are six in the first row. Six, seven, eight, nine, 10, 11,
12. Two times six equals 12.
Next, we need to find three times
three. How many doughnuts are there in
three columns of three? Let’s count in threes to find the
answer. Three, six, nine. Three times three equals nine.
Finally, we have to calculate three
times six. We already know that two times six
is 12. Three times six will be six
more. 12, 13, 14, 15, 16, 17, 18. Two times three equals six. Two times six equals 12. Three times three equals nine. Three times six equals 18. We found the missing numbers using
