To help Year 7 students understand ratios better through market research, we can use some fun and practical activities. These ideas will show how ratios work in everyday situations.

Fun Group Activities

1. Surveys and Collecting Data

   • Students can ask their friends or other people at school about their favorite snacks, prices, or how much they buy.
   • For example, if a group asks 100 students about their top snack choices and finds that:
     • 40 like chips,
     • 30 like candy,
     • 30 like fruit,
   • They can find the ratios of these snacks:
     • Chips: 40 out of 100, which simplifies to 2:5
     • Candy: 30 out of 100, which simplifies to 3:10
     • Fruit: 30 out of 100, which simplifies to 3:10

2. Comparing Prices

   • Groups can look at the prices of similar items at different stores.
   • For example, if Store A sells a pack of 20 cookies for $4 and Store B sells a pack of 15 cookies for$3, students can find out which store has a better deal.
   • They can calculate the price per cookie:
     • Store A: $4 divided by 20 cookies =$0.20 each
     • Store B: $3 divided by 15 cookies =$0.20 each
   • Then, they can talk about what these prices mean for getting more value for their money.

3. Making Visuals

   • Students can draw bar graphs or pie charts to show their data in a clearer way. This helps them see the ratios better.
   • For example, using the snack survey, a pie chart can show how many people liked each snack.

Conclusion

These activities not only help students learn about ratios but also show them how to use math in real life. This can make them better thinkers and help them analyze different situations, which is really useful for market research.
