Diving into Mastery Guidance for Educators Each activity
- Slides: 9
Diving into Mastery Guidance for Educators Each activity sheet is split into three sections, diving, deeper and deepest, which are represented by the following icons: Diving Deeper Deepest These carefully designed activities take your children through a learning journey, initially ensuring they are fluent with the key concept being taught; then applying this to a range of reasoning and problem-solving activities. These sheets might not necessarily be used in a linear way. Some children might begin at the ‘Deeper’ section and in fact, others may ‘dive straight in’ to the ‘Deepest’ section if they have already mastered the skill and are applying this to show their depth of understanding.
Aim • Calculate the area of parallelograms and triangles.
Area of a Triangle (1) Diving Which of these triangles has an area that is not a whole number? A B Give the area of the other triangle. Triangle b has an area of 24. 5 cm 2 16 cm 2 Each square represents 1 cm 2.
Area of a Triangle (1) Diving Estimate the area of these triangles. a) b) Your estimate should be between 17 cm 2 and 18 cm 2. Your estimate should be between 13 cm 2 and 14 cm 2. Each square represents 1 cm 2.
Area of a Triangle (1) Deeper Alfie has been finding the area of this triangle by counting the squares. Explain the error Alfie has made. Whole squares = 12 cm 2 Part squares = 1 cm 2 12 cm 2 + 1 cm 2 = 13 cm 2 Alfie has counted all the whole squares. He has then estimated that all of the remaining part squares have a value of only 1 cm 2, which is incorrect. The remaining part squares have a value of 4 cm 2.
Area of a Triangle (1) Deepest I cut triangles out from this piece of 1 cm 2 paper. Estimate the area of paper that is left over from the original piece after I have cut all the triangles out. Triangle A Triangle B Triangle C B A Triangle D Triangle E C D E
