Using orange juice 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Working with Students Further Resources This task is about working out capacities. Useful Information: 1 litre (l) = 1000 millilitres (ml) This bottle holds 2.5 litres of juice when it is full. Question 2Change answer a) How many millilitres are in a full bottle? ml Question 2Change answer b) The full bottle tipped over and 500 ml of juice was spilt. b) The full bottle tipped over and 500 ml of juice was spilt. How many litres would be left? litres Question 2Change answer c) Jane needed 500 ml of juice for each bowl of punch she was making. c) Jane needed 500 ml of juice for each bowl of punch she was making. How many bowls of punch could she make from one full bottle of juice? Question 2Change answer d) If you poured 20 glasses of juice from a full bottle, there would be no juice left. d) If you poured 20 glasses of juice from a full bottle, there would be no juice left. How many millilitres does each glass hold? ml Task administration: This task can be completed with pen and paper or online (with NO auto marking). Level: 4 Curriculum info: Maths, Geometry and Measurement, Measurement Keywords: capacity, conversion of units Description of task: Students answer questions that involve calculating the capacities of different situations. Curriculum Links: This resource can help to identify students' understanding of measurement units of capacity and multiplicative strategies. Learning Progression FrameworksThis resource can provide evidence of learning associated with Measurement sense, sets 6-7Multiplicative thinking, sets 6-7 within the Mathematics Learning Progressions Frameworks.Read more about the Learning Progressions Frameworks. Answers/responses: Y8 (10/1997) a) 2500 easy b) 2 [Accept if = (a) – 500) ÷ 1000).] easy c) 5 [Accept if = a) ÷ 500.] easy d) 125 [Accept if = a) ÷ 20.] difficult Diagnostic and formative information: Student response Likely calculation Likely reason a) 250 Assumes 1 litre = 100 ml. b) 2000 Answers in ml not litres. c) 2 1000 ÷ 500 Reads '1 litre' instead of '1 full bottle'. d) 250 2500 ÷ 10 Calculates for 10 glasses rather than 20.
