Below are 3 whole chocolate bars. Each chocolate
bar is made up of ten pieces. You can just see
the ten pieces through the wrapping.
We need to share the chocolate between two people
(Steph, John).

Step 1 Give each person a whole bar.
Step 2 We need to remove the chocolate bar from
the wrapper so we can share these tenths between
John and Steph.
5 tenths go to Steph and 5 tenths go to John

Below are 4 whole chocolate bars. Each chocolate
bar is made up of ten pieces. You can just see
the ten pieces through the wrapping.
We need to share the chocolate between five
people (Adam, Bruce, Craig, Dave and Ed).
Step 1 There are 5 people and only 4 bars so we
cant give out whole bars. First we must remove
the wrappers. So we can share out the tenths.

people what is 40 5 ?
8, so each person must get 8 tenths

Record how many wholes there are and how many
tenths.

1. 6 4 ?
2. 6 5 ?
3. 8 10 ?
4. 7 5 ?
5. 7 2 ?

1 whole and 5 tenths
