the numbers you will be working with in this time table is to
skip count ...

Learning
to Divide by 7s
Do you remember that the
÷ sign means divide? When we see the ÷
sign we say divided by. Division is a type of reversed
multiplication. It just takes a wee bit of practice. (NOTE: 0
divided by any number equals 0)
Be sure to practice skip
counting as it helps us to divide quickly ...

When one thing or a number
of things is divided into seven equal parts, each part is called
one seventh. One seventh is written 1/7. We
can find 1/7 of any number by dividing the number by 7.

Before you go on to the 8s
times tables, be sure to ...
1) Review
your skip counting for all the times tables you have done so far
... frontwards and backwards
2) Have your daddy,
mama, sister, or brother flash
you all the multiplication/division facts you have learned.
See how fast and accurate you can be !
3) complete the Multiplication Chart
for
what you already know !
