Notice how each row is seven more
than the previous one. One times seven equals seven, two
times seven equals 14, three times seven equals 21. Find the result of the following:
five times seven equals what. Find the result of the following:
seven times seven equals what.
This question is all about the
seven times table. The first model shows one lot of
seven. Then, we add seven more to show two
lots of seven and seven more to show three lots of seven. As we add seven each time, the
result increases by seven. One times seven is seven, two times
seven equals 14, and three times seven equals 21. As we add seven, we’re counting on
in sevens. One seven is seven; two sevens are
14; three sevens are 21.
We’re being asked to find the
result of five times seven. So, if three times seven is 21, we
just need to add seven more to find four times seven. 21 plus seven is 28. And we can add one more seven to
find five times seven. What is 28 plus seven? It’s 35. Finally, we have to find the result
of seven times seven. We already know that five times
seven is 35. To find six times seven, we just
need to add another seven. 35 plus seven is 42. And to find seven times seven, we
just need to add one more seven.
We knew from the model that one
times seven is seven, two times seven is 14, and three times seven is 21. We continued counting forward by
seven each time to find five times seven, which is 35, and seven times seven, which
is 49. When we’re multiplying by seven, we
can skip count by seven to help us find the result.
