Vocabulary Quad -‐ prefix meaning 4, ver3ces, sides, angles, 2 dimensional shape, quadrilateral, square, rectangle, rhombus, trapezoid, trapezium, kite, diamond, parallelogram, convex, concave, parallel, congruent, degrees Ac,vity Process: Se5ng the Scene The purpose of this ac/vity is to review the concept of quad -‐ meaning 4. Ask learners to suggest any words they know which start with the prefix quad. Display the words -‐ quadrant, quadruple, quadrangle, quadriceps, quadriplegic and display the ques3on -‐ What is the connec4on between these words? Ac,vity Process: Review The purpose of this ac/vity is to relate the term quadrilaterals to ‘4’ -‐ 4 sides, 4 corners. Introduce the term quadrilateral using hEp://goo.gl/qzjvOQ on the Interac3ve Whiteboard. Learners will use individual whiteboards (with grid) or ipads to prac3se drawing each shape using the characteris3cs discovered when hovering over the shapes. Ask students in pairs to THINK, PAIR, SHARE a defini3on of quadrilaterals using the informa3on gained from the site -‐ eg. Quadrilaterals are 2 dimensional shapes with 4 sides and 4 corners. Write on whiteboards and share. Use these to create a class defini3on to be displayed on chart paper. Watch You Tube Clip -‐ Know Your Quadrilaterals hEp://www.youtube.com/ or Quadrilaterals Powerpoint Presenta3on from slide 2 onwards goo.gl/Z7VSMb Ask learners to name the family of closed, plane, 2D, mul3ple sided shapes-‐Quadrilaterials
belong to?
Key Idea: • Iden3fy quadrilaterals by aEributes. • Dis3nguish quadrilaterals from non-‐quadrilaterals. • Analyze quadrilaterals to iden3fy specific
members (square, rectangle, trapezoid, parallelogram and rhombus) of the group.
• relate common 3D shapes and their nets to quadrilaterals
Resources • FISH Problem Solving • grid paper • Ruler • individual whiteboards (with grid) and pens • iPad Apps -‐ Dic3onary.com, Kahoot.it • 2d shape cut outs (pictures of various 2d shapes to sort) • chart paper and pens • geoboards and dot paper • rubber bands • 3d shapes • 3D nets
Australian Curriculum Year 5 ACMMG111 connect three-‐dimensional objects with their nets and other two-‐dimensional representa/ons
Ask learners to use a dic3onary or dic3onary app eg. Dic3onary.com to find the commonality of meaning of words beginning with quad and come up with a similarity to answer the ques3on. Focus of answers -‐ they all relate to the number 4 (or similar). Create a display in the classroom using the prefix Quad -‐ means 4 of something. Alternately use either inspira3on app on an ipad or hEp://quizlet.com/7181872/prefix-‐tri-‐and-‐quad-‐words-‐flash-‐cards/
Ac,vity Process: Meet the Quadrilateral Family The purpose of this ac/vity is to revise the types of quadrilaterals and their features. hEp://www.regentsprep.org/Regents/math/geometry/GP9/LQuad.htm Gives more informa3on about quadrilaterals and the features of each shape. In groups, create charts of each type of quadrilateral for display. (Can be either hand-‐made or linking to ICT) Focus on describing the sides and angles as parallel or congruent and look at the size of the angles in each shape hEp://www.pinterest.com/pin/247135098274650477/ Students use the informa3on to make “Which Quadrilateral am I?” Kahoot Quiz INSTRUCTIONS FOR USING KAHOOT To begin, you need to set up a free account which asks for the usual contact details. Once logged in there is a quick tutorial which outlines the basic features of the site. Then, it's up to you to explore the public quizzes or create your own. (There are quizzes already made about quadrilaterals, but they might not suit your cohort)
To create a quiz, select the ? icon. Simply give the quiz a 3tle and then type in the ques3ons and responses, selec3ng the correct answer. You have the op3on to upload a picture if you want, change the number of responses to choose from and allocate points for correct answers. Once all ques3ons have been created, click on Next: SeBngs in the boEom right hand corner. You will then be prompted to complete the administra3ve side of the quiz. When it is complete it is saved into your file (me).
To play, first of all students will need to open Kahoot.it in their internet browser. To save 3me on the next quiz, add the icon to the home screen -‐ it then looks like an app. Now on the computer, select the quiz you want the students to complete and press play, then launch. A screen will appear promp3ng you to connect mobile devices.
Alterna3vely, create ‘Which Quadrilateral Am I?’ cards to play in groups, snap cards or Folding Cards with the name of the quadrilateral on the top and features underneath. Or alternately for your more able learners, play Quadrilateral Dominoes a set cards available from: hEp://www.greatmathsteachingideas.com/wp-‐content/uploads/2012/02/Proper3es-‐of-‐quadrilaterals-‐dominoes-‐game-‐ssm1-‐level-‐5-‐level-‐6.pdf
Follow the prompts and the devices connect easily. Then select start now. The number that is displayed must be typed into the mobile devices and then select play. The students then answer the ques3ons using their mobile device. The students will beg you to play again.
Ac,vity Process: The purpose of this ac/vity is to iden/fy shapes that are quadrilaterals and are not quadrilaterals, based on the features discussed. Ask learners to make a chart with examples and non-‐examples of quadrilaterals. Use various 2D shape cut outs to sort into examples and non-‐examples. Students must explain why they are or are not quadrilaterals, using the terminology already learnt -‐ eg. I think that this square is an example of a quadrilateral, because it has 4 sides, 4 corners and 2 sets of parallel lines. This triangle is a non-‐example of a quadrilateral because it has 3 sides and 3 corners.
Show and discuss this prezi with class hEp://prezi.com/3r_upm-‐rwo3m/the-‐history-‐of-‐quadrilaterals/ Scootle -‐ Building Bridges: Quadrilaterals. hEp://www.scootle.edu.au/ec/viewing/L1924/index.html Inves3gates proper3es of simple quadrilaterals used to make a bridge. Links with graphing, number paEerns and mul3ples. Ac3vity: Learners use a digital camera to photograph a variety of 3D objects from different perspec3ves, including top, side and front view which they print. Learners outline the edges of the faces with a pencil and cut out each face separately. They answer the ques3on-‐What shape are the faces in this view? A partner re-‐assembles the faces as a jigsaw, using a copy of the original photo as a guide. Learners draw the shapes that make each of the 3D objects and label each shape. Extension Maths & Art Revision-‐Point, Lines and Plane
In visual arts, students are open required to recognise measure, draw and construct three-‐dimensional objects. Drawing represents shapes drawn on a flat surface called a Plane. A plane is two-‐dimensional (2D) it is a flat surface
Learners need to be familiar with key terms used to describe lines, two-‐dimensional shapes and three-‐dimensional objects. When making artworks, it is important that learners are able to recognise, visualise and draw two-‐dimensional shapes and three-‐dimensional objects. Learners make linear (using only line) drawings of several objects from observa3on. Learners imagine, then draw the 'invisible' edges of these objects. To emphasise the three-‐dimensional quali3es of the objects, add shadows and shading.
Ac,vity: Revision-‐2D and 3D Concepts hFp://www.bgfl.org/bgfl/custom/resources_Kp/client_Kp/ks2/maths/3d/index.htm Show students a variety of 3D shapes -‐ students name the shape and discuss the features -‐ eg. shape of each face. Make a list of the shapes that contain quadrilaterals -‐ Cube, Prisms, square based pyramid etc. Show the net of a rectangular prism and ask students to iden3fy the number of quadrilateral faces. Con3nue with other shapes. Nets available at hEp://www.greatmathsteachingideas.com/wp-‐content/uploads/2012/03/Making-‐3D-‐Shapes.pdf Ac,vity: Around Us Quadrilaterals are all around us, from computer screens to buildings, to sheets of paper. Many objects are made up of quadrilaterals, for example, bridges, towers and houses, so knowledge of the proper3es and features of these shapes is paramount to understanding how things are constructed.
In ancient 3mes, quadrilaterals were used in Art, design and architecture. Many current occupa3ons use quadrilaterals -‐ eg. architects, designers, computer and mathema3cal occupa3ons etc.
In Pablo Picasso cubist period he began pain3ng subjects that were made of cubes, spheres, cylinders, cones and other geometric shapes. He wanted to show all the sides of an object in the same picture. Ask learners to iden3fy the subject of this picture and the 3D objects used by Picasso.
