Mathematics Year 1: (1M2) Measure and begin to record: mass/weight

Mathematics Year 1: (1M1) Compare, describe and solve practical problems for: mass/weight [for example, heavy/light, heavier than, lighter than]

Mathematics Year 2: (2M1) Compare and order lengths, mass, volume/capacity and record the results using >, < and =

**Differentiation for Year 1 Introduce Weight and Mass:**

**Varied Fluency**

**Developing **Questions to support developing their understanding of weight and mass. Using a balance scale and images of objects clearly different in weight or mass, i.e. a mouse and an elephant. Including language of heavier and lighter.

**Expected **Questions to support developing their understanding of weight and mass. Using a balance scale and images of objects similar in weight or mass, i.e. a cat and a dog. Including language of heavier, equal and lighter.

**Greater Depth **Questions to support developing their understanding of weight and mass. Using a balance scale and images of objects similar in weight or mass, where sometimes the weight of two objects must be used to determine the weight of another object. Including language of heavier, equal and lighter.

**Reasoning and Problem Solving**

**Questions 1, 4 and 7 (Reasoning)**

**Developing **Explain if a statement is correct. Using a balance scale and images of objects clearly different in weight or mass, i.e. a mouse and an elephant. Including language of heavier and lighter.

**Expected **Explain if a statement is correct. Using a balance scale and images of objects similar in weight or mass, i.e. a cat and a dog. Including language of heavier, equal and lighter.

**Greater Depth **Explain is a statement is correct. Using a balance scale and images of objects similar in weight or mass, where the weight of two objects must be used to determine the weight of another object. Including language of heavier, equal and lighter.

**Questions 2, 5 and 8 (Problem Solving)**

**Developing **Use their knowledge to predict what the scales would look like when weighing two objects. Use the balance scales and images to complete the question.

**Expected **Use their knowledge to predict what the scales would look like when weighing two objects. Use the balance scales only to complete the question.

**Greater Depth **Use their knowledge to predict what the scales would look like when weighing two or more objects. Use the balance scales only to complete the question.

**Questions 3, 6 and 9 (Reasoning)**

**Developing **Identify the correct object that will be lighter or heavier from the 2 objects provided.

**Expected **Identify the correct object that will be lighter, equal or heavier from the 3 objects provided.

**Greater Depth **Identify the object that will be lighter, equal or heavier from the 4 objects provided.

**Differentiation for Year 2 Compare Mass:**

**Varied Fluency**

**Developing **Questions to support comparing mass. Obvious difference between weights where size is congruent to weight.

**Expected **Questions to support comparing mass. Subtle difference between weights where size is congruent to weight.

**Greater Depth **Questions to support comparing mass. Challenging difference between weights with size which may be incongruent to weight.

**Reasoning and Problem Solving**

**Questions 1, 4 and 7 (Reasoning)**

**Developing **True or false. Compare the mass of two objects which are obviously differing in size and mass.

**Expected **True or false. Compare the mass of two objects which differ somewhat in size and mass.

**Greater Depth **True or false. Compare the mass of two objects which are similar size and mass.

**Questions 2, 5 and 8 (Problem Solving)**

**Developing **Use given 2 scales to compare the mass of two items not present on the same scale. The mass of items is congruent with their size.

**Expected **Use 2 given scales to compare the mass of two items not present on the same scale. The size of items does not reflect their mass.

**Greater Depth **Use 3 given scales to compare the mass of two items not present on the same scale. The size of items does not reflect their mass, there maybe more than one of each item on scales.

**Questions 3, 6 and 9 (Reasoning)**

**Developing **Consider and reason statements about given scales. Statements use language of mass comparison. The mass of items is congruent with their size.

**Expected **Consider and reason statements about given scales and decide if correct. Statements use symbols of mass comparison. The size of items does not reflect their mass.

**Greater Depth **Consider and reason statements about given scales and decide if correct. Statements use symbols of mass comparison. The size of items does not reflect their mass, there maybe more than one of each item on scales.
