1 Lesson Plan - APP Area and Perimeter ObjectivesTo pupils to self assess their understanding of area and perimeter. For teacher to carry out an APP assessment using probing questions.Keywords : Area, Perimeter, FormulaMental and Oral StarterPupils to complete a ‘Heard the Word’ grid and compare it to grid they completed at the start of the unit.MainShow the pupils the assessment criteria (slide 5) and ask them to reflect on what they have done over the last few lessons. This will give pupils an idea about which challenge they should try to complete. Ask pupils to select an appropriate challenge. Explain that the purpose of this lesson is to assess their understanding so although they can ask a friend for help they must be honest when they come to self assess at the end of the lesson. Explain that if they find their chosen challenge either too hard or too easy they should swap for a different challenge. Ensure that pupils are aware that they only have this lesson to complete their chosen challenge so they must stay on task and work to the best of their ability to be able to accurately assess themselves.PlenaryPrint off slides 11 and 12 two to a page on pink A4 paper. Ask pupils to look at their assessment sheet and colour in all the levels they feel that can achieve independently. Tell pupils that they must complete the ‘Tips / Hints’ box by explaining in their own words the maths they did today. Ask them to also describe any help that they had. Explain to pupils that you will be marking their work and completing the ‘my teacher’s’ boxes. Remind students that next lesson for the starter activity they must come in and look for the question you have set and respond either by answering it or by explaining why the question is too hard for them to answer.
2 Probing QuestionsLevel 4Find areas by counting squares and part squares of shapes drawn on squared paper.How do you go about finding the perimeter of a shape?How are the perimeter of a shape and the area of a shape different? How do you remember which is which?Level 5Find any one of the area, width and length of a rectangle, given the other two.Find the area and perimeter of simple compound shapes made from rectangles.For a given area (e.g. 24cm2) find as many possible rectangles with whole number dimensions as you can? How did you do it?Always true, sometimes or never true? ‘If one rectangle has a larger perimeter than another one, then it will also have a larger area.’Level 6Calculate the area of triangle and parallelogramsThe area of a triangle is 12cm2. What are the possible lengths of the base and height?Why do you have to multiply the base by the perpendicular height to find the area of a parallelogram? You can use a diagram to explain your answer.What other formulae for the area of 2D shapes do you know? Is there a formula for the area of every 2D shape?
3 LO To design a classroom and calculate the perimeter and area of each desk.

5 LO To design a classroom and calculate the perimeter and area of each desk. RAGKey Words: Perimeter, Area, Formula20-Apr-17Today’s Task :-Produce a drawing of a classroom containing 5 different sized / shaped desks to seat 30 pupils.Calculate the perimeter and area of each desk top and provide a quote for the cost of the desks for the client.5
6 Assessment CriteriaTo produced a drawing of a classroom and calculate the area and perimeter of the desks. You should show you can work out area and perimeter.Level 4 ChallengeDesign a classroom with 5 different sized rectangular desks, drawn on squared paper. (1cm = 1m) Calculate the perimeter and area of the desks by counting squares.Level 5 ChallengeDesign a classroom with 5 different sized rectangular and/or triangular desks. Write on the measurements of the sides of each desk. They should not be drawn to scale. Calculate the perimeter of the rectangular desks and the area of all the desks using formula.Level 6 ChallengeDesign a classroom which has 5 different shaped desks, a rectangle, a triangle, a parallelogram, a trapezium and a kite. Write on the measurements of the sides of each desk. They should not be drawn to scale. Calculate the perimeter and area of the desks using formula.
7 The Task You work as part of a classroom design company. A client has approached you to design and give a quote for classroom furniture.They have a few stipulations which you need to follow.You will need to provide a quote for the cost of the desks, you can either choose which type of desk to supply or you can provide more than one quote.
8 The Client’s Stipulations The desks can be any shape but they must be large enough to seat pupils in groups, so more than one pupil at every desk.There must be 5 desks in the room.30 pupils must be seated around these 5 desks, however, group sizes can change so you could have a smaller desk seating 2 or 3 pupils and larger desks seating 4 or more pupils.
9 Providing a quote for the client Economy desk tops costs £5 per metre2.Standard desk tops costs £7.50 per metre2.Luxury desk tops costs £11.75 per metre2.You must round to the nearest whole metre when calculating cost.
10 Your work will be assessed on: The accuracy of your calculations.The presentation of your ideas and designs.The presentation of your calculations and results.
