Reasoning 1 Is the following statement correct? 80 1000 L < Explain your answer. © Classroom Secrets Limited 2018 800 ml = 0. 8 L

Reasoning 1 Is the following statement correct? 80 1000 L < Explain your answer. Yes, it is correct because… © Classroom Secrets Limited 2018 800 ml = 0. 8 L

Reasoning 1 Is the following statement correct? 80 1000 L < 800 ml = 0. 8 L Explain your answer. Yes, it is correct because 80 = 80 ml, so 80 ml < 800 ml. 100 L 0 0. 8 L x 1, 000 = 800 ml, so 800 ml is the same as 0. 8 L. © Classroom Secrets Limited 2018

Reasoning 2 Elijah’s bucket can hold 3, 600 ml. Mason’s bucket can hold 4. 2 L. Both fill their buckets half way. Elijah adds an extra 800 ml and Mason adds an extra 400 ml. Elijah says, My bucket has the least amount of water. Is he right? Explain how you know. © Classroom Secrets Limited 2018

Reasoning 2 Elijah’s bucket can hold 3, 600 ml. Mason’s bucket can hold 4. 2 L. Both fill their buckets half way. Elijah adds an extra 800 ml and Mason adds an extra 400 ml. Elijah says, My bucket has the least amount of water. Is he right? Explain how you know. No because he has 2, 600 ml in total (3, 600 ml ÷ 2 = 1, 800 ml and 1, 800 ml + 800 ml = 2, 600 ml). Mason has 2, 500 ml in total (4. 2 L ÷ 2 = 2. 1 L and 2. 1 L + 400 ml = 2, 500 ml). Elijah’s bucket has 100 ml of water more than Mason. © Classroom Secrets Limited 2018
