Geometry and measures Derive and apply formulae to calculate and solve problems involving: perimeter and area of triangles, parallelograms, trapezia, volume of cuboids (including cubes) and other prisms (including cylinders)ĭr Frost is a maths teacher working at Tiffin School in London.There are a couple of worksheets é a matching activity to accompany the PPTs. The 10RS one is a very thorough look at area é perimeter focusing on all 2D shapes including circles, moving at a very slow pace. Find what fraction of a shape is shaded by splitting into congruent shapes. The 7RA one focuses more on perimeter é slowly goes through the area of 2D shapes (exc.Appreciate that triangles have the same area if their base and height are the same, and compare sizes of triangles by considering the proportion of base/height. Save time and enhance your teaching with our collection of KS3-4 resources for teaching area and perimeter.Appreciate strategies to find areas of composite shapes, by (i) adding areas (ii) subtracting areas, including appreciation of the ‘frame’ method and (iii) cutting/reforming areas.Find the area and circumference/perimeter of circles and fractions of circles (eg 1/2, 1/4).Find the area of a triangle, trapezium, parallelogram.Find the perimeter and area of rectilinear shapes.The questions are sequenced so that pupils can begin to see and notice the shifting of perimeters, as a link with compound perimeter problems and visualising the sliding of parallel lines to make lengths. I’ve struggled to find it for the last few weeks so I’ve made my own version. There was a resource I used to use years ago around ‘nibbled’ perimeters. Twinkl KS3 / KS4 Maths KS3 Maths - Full Collection Geometry and Measure Area, Perimeter and Volume Area Circles. The link is just below: Area and Circumference of Circles WorksheetsIt acts as a great supporting resource for the Area Questions found on this page and would fit perfectly into a KS3 Maths home learning programme. Round to the correct degree of accuracy and include the units. We do, however, have an excellent resource that helps KS3 Maths pupils to develop their skills in area and perimeter. “Move the end on one across and add two to the top and bottom to complete the rectangle.” Substitute the radius (r) into the formula. The Area and Perimeter Worksheet Pack includes: 1. “You’d add four lines on and then off the double line inside.” Beyond has endeavoured to bring a practical and interesting resource to you that can challenge your KS3 Maths pupils in various ways. “You’d add three lines on and then take off the one on the inside.” Showing pupils some maths and asking them to explain it is powerful AfL for us as teachers to see where kids are at with communicating maths through a speech, a precursor of writing it down.įor the above conditions I had the following responses: “Year 7, some people might look at this and think that four squares will have a perimeter of 10 units, but watch this!”įollowing with this up with reasoning around why adding a square in a line is a definite way to increase the perimeter by two helps train pupils out of that ‘there’s always just a right or wrong answer in maths’, and brings in increasing conditions for mathematical knowledge. No matter what the level of mathematics in lesson (the above screenshot and the one below were taken from our year 7 nurture group) conjecture and argument have a place.Īgain, the aim is not to catch pupils out with the 4 squares also having a perimeter of 8, but was presented in a way that is a big sneaky secret. Even in the task below, it took a lot of modelling and using the visualiser to get them to look at individual line segments rather than the number of lines in the shape. ![]() ![]() Secondly, pupils really struggled divorcing the number of squares (we’re avoiding the word area here) from the perimeter. (Similarly, Pilot V Board Master Chisel Tip Medium Refillable pens? No contest. This post, and the subsequent post, address two approaches I’ve taken.įirstly, I can’t recommend projecting a square excel spreadsheet on the board with border shading enough for a quick and dirty square whiteboard. Round to the correct degree of accuracy and include the units. 1 Solutions for the assessment Area and Perimeter 1) Perimeter 80 cm 3) Perimeter 88 cm 5) Perimeter 28 cm 7) Width 18 cm 9) Perimeter 16 cm 2) Area 336 cm 2 4) Area 15 cm 2 6) Area 63 cm 2 8) Area 52. Substitute the radius (r) into the formula. Separating perimeter from area has a whole host of benefits in allaying misconceptions around dimensional differences between lengths and areas, but this often means that reasoning and teaching to greater depth with perimeter exclusively can be more challenging. Calculating the area of a circle - example: Calculate the area of a circle with a radius of 6cm, giving the answer correct to 1 decimal place.
