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. chocolate We need to share the chocolate between two people (Steph, John). Step 1: Give each person a whole bar. John Steph 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 Steph John Both John and Steph have 1 whole and 5 tenths. Number of tenths

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. chocolate 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 can’t give out whole bars. First we must remove the wrappers. So we can share out the tenths Number of tenths Bruce Craig chocolate Step 2: Share them out. We have 40 tenths and 5 people what is 40 ÷ 5 = ? 8, so each person must get 8 tenths Adam Dave Ed Each person received 8 tenths.
