3. Progression within the lesson

• Homework (grade C-B)

• Starter (E)

• Modelling

• Paired tasks (D-B, differentiated by outcome)

• Independent learning (E-A, differentiated by outcome)

• Review and Reflection

4. Homework

• By the end of this lesson you will be able to solve questions of this type for homework:

• Your homework is to

• Complete a set of questions in a text or do an online activity on Mymaths.co.uk by

5. Starter

• True or false?

• Mini-whiteboards used by students, they decide if each inequality is either true or false.

• The more able can be asked to explain why.

6. Modelling

• Taking an example from the starter they should all understand.

7. Modelling

• What other values of x make this inequality true?

• Different students can be stretched by going beyond Integers.

• What other numbers can be used?

• Find 3 interesting numbers that make this true

8. Modelling

• What about this one?

• Can you see a method for solving this inequality?

• The concept is developed, as is the language.

9. Modelling

• What about this one?

• Can you see a method for solving this inequality?

• Questions using how and why can extend some students and to assess the level of understanding.

10. Modelling

• What about this one?

• Can you see a method for solving all inequalities?

• How could you check your answer is correct?

11. Paired work

• Make an inequality for your partner (and solve theirs)

• Create 3 inequalities with the solution x>3. Check your partners is correct.

• Teacher and any support staff circulate and help the students as required.

12. Independent learning (rich tasks)

• A variety of rich tasks would then be used. These are problem solving tasks that differentiate by allowing the students to carry out an open ended task.

• They are student (as opposed to teacher) led.

• They link areas of maths together (number, shape, algebra, using and applying maths).

13. Task 1: Number

• An abundant number is a number where all the

• factors add up to more than the number itself

• Can you find any abundant numbers?

• What do you notice about them?

• Extension: Deficient and perfect numbers

14. Task 2: Shape and space

• Find rectangles with area less than, equal to and

• greater than the perimeter

• what do you notice?

• Extension: try some other shapes?

• Extension: Can you find all the cuboids with

• surface area = volume?

15. Task 3: Extension

16. Review and Reflection

• What have we been doing?

• Solve this inequality on your whiteboard

• A review of the learning using directed questioning to assess understanding. This will be linked back to the success criteria and empower them to complete the B grade homework!
