2. A collaborative task in the Comenius- eTwinning project AIMS- Alternatives for Innovative Math Study 3. Ingredients for 10 portions: For the dough: *1,75cupsflour *apinchofsalt, *3/4cupbuttercutintosmallpieces, *4-5tablespoonsofcoldwater.

Pourthefillingintothebakedpiecrust.Chillthoroughly. The Recipe 5. Calculate the ingredients you need for the number of portions according to your group, in grams. Calculate the ratio between the flour and the butter. Calculate how much a portion of the pie would cost- show us your calculations and the unit costs for each ingredient. In the end, create a bar chart with the cost of the same piece of pie in all the partners towns. One cup = 250 grams One tablespoon = 20 grams The Tasks 6. Calculate the average cost and the difference between this and the cost in your town. Calculate the baking temperatures assuming your oven is labeled in Fahrenheit, not Celsius. Use the formula F=9/5*C+32 Optional: bake the pie and show it to the partners! The Tasks 7. Dont forget to take photos so we can see you at work! Piece of pie, isnt it? Enjoy the task, and the pie!
