Some 2D shapes will tessellate well, whilst others will not. First name the shapes and then sort them into the columns according to whether you think they will tessellate: Will Tessellate Will not tessellate Name: Name: Name: Name: Name: Name: Name: Name: What do you notice? Week 7: 8th June Ridge Class Maths You can create your own tessellating shape using a piece of cardboard and some tape. You can make your shape using one of three different mathematical movements: • translation (moving up or down, left or right) • rotation • reflection (flipping) First, identify whether these shapes have been translated, rotated or reflected: Now have a go at creating your own tessellation pattern using the instruction sheet provided. Colour your pattern in – you could choose a repeating pattern to make it even more mathematical. Week 7: 8th June Ridge Class Maths For all tessellations, you need to start with a square of paper or card to create your stencil. You then have three choices: • translation • rotation • reflection Translation 1. Draw a line from one corner, to the adjacent corner (the one next to it not opposite it) 2. Cut along that line 3. Move the cut piece without flipping it to the opposite side of your square. 4. You can stop there or repeat the process by drawing a line between two different corners. 5. Once you’re done, draw around the shape onto paper, leaving no gap between each one. Week 7: 8th June Ridge Class Maths Rotation 1. Start exactly like translation 2. Instead of just moving your piece to the opposite side, you turn it and move it to the side that is next to where you cut it from. 3. Do the same with another cut if you would like to 4. Draw around your shape. This time you will have to rotate your shape every time you draw it. Reflection 1. Start exactly like translation. 2. This time you move the piece to the opposite side, then flip it over and stick it down. 3. Do the same with another cut if you would like to 4. Draw around your shape, flipping it each Week 7: 8th June Ridge Class Maths Day Two: Tessellation ANSWERS Will Tessellate: rectangle, rhombus, trapezium, parallelogram, isosceles triangle, hexagon Will not tessellate: Circle, pentagon, This is tricky – all quadrilaterals with a pair of parallel lines will tessellate. Other shapes e.g. hexagon have to have interior angles that are a divisor of 360ᵒ a) reflection b) rotation c) translation d) translation e) reflection f) rotation Week 7: 8th June Ridge Class Maths Day Three: Volume The volume of an object is the amount of space that it takes up. We are going to revise how to find the volume of a 3D cuboid/cube. The three important measurements that we will need to find the volume are the height, length and depth: Look at this cube. We could find the area of the red top section by doing its length x depth or 3 x 3 = 9 cm² (It takes 9 cubes to make it). You can then see that there are 3 layers of those 9 cubes. So 3 x 3 x 3 = 9 x 3 = 27cm³ This time we write cubed after the measurement because it is how many cubes it would take to make it, not how many squares (like area) So to find volume we do: length x height x depth and we write ³ after our measurement Week 7: 8th June Ridge Class Maths Try It Find the volume of these cuboids: a) b) Volume: Volume: Week 7: 8th June Ridge Class Maths Use It Prove It Week 7: 8th June Ridge Class Maths Day Three: Volume ANSWERS Try It a) 8 x 4 x 5 = 8 x 20 = 160cm³ b) 6 x 4 x 2 = 6 x 8 = 48cm³ c) 5 x 2 x 3 = 10 x 3 = 30cm³ Use It 9 x 2 x 5 = 90cm³ 7 x 2 x 4 = 56cm³ 90 + 56 = 146cm³ Week 7: 8th June Ridge Class Maths Box A = 40 x 4 x 4 = 160 x 4 = 400 + 240 = 640cm³ Box B = 25 x 5 x 6 = 125 x 6 = 600 + 120 + 30 = 750cm³ Box C = 30 x 6 x 4 = 180 x 4 = 400 + 320 = 720cm³ Box C would be most suitable as it will fit all of the cereal inside without leaving too much space. Prove It a) l x h x d = 72cm³ First find factors of 72. Then find factors of those numbers to help you find them all. 72 x 1 x 1 9 x 4 x 2 36 x 2 x 1 12 x 3 x 2 24 x 3 x 1 6 x 6 x 2 18 x 4 x 1 18 x 2 x 2 12 x 6 x 1 6 x 4 x 3 9 x 8 x 1 8 x 3 x 3 b) 96 x 1 x 1 48 x 2 x 1 32 x 3 x 1 24 x 4 x 1 16 x 6 x 1 12 x 8 x 1 24 x 2 x 2 16 x 3 x 2 12 x 4 x 2 8 x 6 x 2 8 x 4 x 3 6 x 4 x 4 Week 7: 8th June Ridge Class Maths Day Four: Time Week 7: 8th June Ridge Class Maths Week 7: 8th June Ridge Class Maths Week 7: 8th June Ridge Class Maths Day Four: Time ANSWERS Week 7: 8th June Ridge Class Maths Day Five: Statistics Reading tables and charts Use this chart of Pokémon to answer the questions.
