2D Shapes Week 8
Two-DimensionalShapesMaths Week 8Remote LearningLesson 1Learning Intention:We are learning to describe translations,reflections and rotations of two-dimensionalshapes.
Maths TalkWhich one doesn’t belong?Answer these questions to the best of your ability:1. Where you might see a reflection in everyday life?2. What it means to rotate an object?3. What it might mean to translate/slide an object?
TransformationsDraw a line to the correct name and example:Rotations are aFlipReflections are aSlideTranslations are aTurn
Write if each figure was translated,reflected or rotated:
Create ashape andtransformthese shapesaccording totheinstructions.The first onehas beendone for you.Optional: Get Creative!Cut and create shapes out of coloured cardboard.Use these shapes to help create a translation,rotation and reflection of the shape.Glue shapes on paper or create a poster to choseyour knowledge of the three transformations, withdefinitions. An examples has been included:
Lesson 2Learning Intention:We are learning to explore symmetry andtessellations.Maths TalkWhat can you tell me about this?
What is symmetry?Something is symmetrical when itis the same on both sides. A shapehas symmetry if a central dividing line(a mirror line) can be drawn on it, toshow that both sides of the shape areexactly the same.Can you draw a symmetrical shape?Draw a line througheach shape to show itsline of symmetry.*Hint, there may be more thanone.Then, write how manylines of symmetry eachshape had.
Symmetry ActivitiesTry to complete at least two activities below. Tick the activities completed:Legos:Make shapes outof lego that willhave a least a lineof symmetry.1)4) Flags of theworld:Investigate flags ofthe world that havesymmetry or, createyour own flags whichhave symmetry.2) SymmetricalDesigns:Get creative and drawsymmetrical designsusing 1, 2 and 4 lines ofsymmetry on paper asshown in the diagrambelow.Examples:5) Nature Symmetry:Go outside and findnatural objects thatyou can createsymmetry with. Somenature objects youcould use:3) Origami:Explore lines ofsymmetry in a rangeof 2D shapes bycreating and thenfolding cut-outs ofvarious shapes.6) Natural Symmetry:Research naturalsymmetry and make alist or poster of yourfindings. Examples:-ButterfliesMountain reflection
Lesson 3Learning Intention:We are learning to identify if shapes haverotational symmetry.Maths TalkTell me about these lines of symmetry:
TessellationsWhich of these 2D shapes tessellate? Tick or highlight the shapes you think tessellate:
Tessellation ArtYou are going to create your own tessellation monster.Follow the following steps to create your monsterORYou can create your own tessellated shape/collage instead.
Tessellation Art Monsters Examples
Lesson 4Learning Intention:We are learning to explore symmetry andtessellations through artMaths TalkWhat can you tell me aboutthis image? Use mathematical vocabularyin your answer.
Rotational SymmetryA shape has rotational symmetry if it can be spun about apoint within a figure so that it repeats its shape and more thanonce in a complete revolution.Example:
Optional Activity:Rotational (turning) symmetry-Trace a shape and pin the tracing to the shape through the centre(use a pencil or pen to do this).The tracing is then rotated around.As it is being rotated, count the number of times the tracing and theoriginal align.If you match before a full turn is completed, the shape has turningsymmetry.Placepen/pencilhere.How many orders of rotational symmetry does your shape have?What is the order ofrotational symmetryfor each of thefollowing shapes?(how many times can it rotateperfectly?)
Art ActivityStepsResources1. Draw a shape on the paper. It can be regular or irregular.2. Cut out shape.3. Place it on another piece of paper.4. Using a push pin or pencil or pen, push it through the center of5.6.7.8.9.your shape.Trace the shape onto the paper underneath.Turn your shape a quarter turn. Trace the shape again.Repeat quarter turn rotation until you have traced the shapefour times in total.Remove push pin/pencil or pen and the first shape on top.Decorate as desired.Art Activity PaperPencilColoured pencils/oilpastels/paint/textasScissorsPush-pin or Pen orpencil
Lesson 5Learning Intention:We are learning to revise what we have learnedin 2D space this week.Maths TalkTell me all about thenumber:8361
