Numeracy Foundation June 2022 Unit 2 Q2
2. Most foods can be frozen and stored in a freezer.
Different freezers have different ‘freezer star ratings’.
The table below shows the temperatures of freezers with different star ratings.
It also shows the maximum length of time that food should be stored in each type of freezer.
| Freezer star rating | Freezer temperature | Maximum length of time food should be stored |
|---|---|---|
| **** | – 18°C | 3 months or longer |
| *** | – 18°C | 3 months |
| ** | – 12°C | 1 month |
| * | – 6°C | 1 week |
(a) What is the difference in temperature between a freezer with a 2-star rating and a freezer with a 4-star rating? [1]
(b)
What star rating should a freezer have if it is to be used to store food for 16 weeks?
Circle your answer. [1]
1-star 2-star 3-star 4-star

| No and suitable reason given relating to time of 3 star and 4 star freezers being different e.g. ‘For 6 months, she needs a 4-star freezer’. ‘because the 4 star means you can store food for longer (than 3 months)’ ‘because June to December is more than 3 months’ ‘because 3 stars is not long enough’ ‘need longer than 3 months’ ‘needs 3 months or longer’ ‘need from June to December which is 6 months’ ‘because the food won’t last until December’ | E1 | Allow: ‘No because from June to December is 7 months’ ‘No because from June to December is 5 months’ Do not allow: ‘No, because they are the same temperature’ ‘No because June to December is 4 months’ i.e., reference to the incorrect number of months. ‘No because the food will go off and you will have to throw it away’ |
