Shape Transformations: Flip, Slide, Turn
Year 4-5 Mathematics Geometry and Spatial Reasoning Exploring how shapes move and change
What Are Shape Transformations?
Shapes can move in different ways They stay the same size and shape Three main types: flip, slide, turn We use everyday words and maths words
Look at These Shapes
Are these the same triangle or different triangles? What do you notice about their position? How might one triangle have moved to become the other?
Te Reo Māori Shape Names
Tapatoru = Triangle Tapawhā rite = Square Tapawhā roa = Rectangle Taparima = Pentagon Tapaono = Hexagon
Mirror Magic Activity
Work with a partner Use mirrors to explore reflections Place shapes against the mirror Describe what you see Use words: flip, reflect, mirror image
Lesson 1 Recap: Seeing Shapes Differently
Shapes can look different from different angles Same shape, different orientation Mirrors show reflections We learned shape names in te reo Māori
Reflections: The Mathematical Flip
Reflection = flip across a line The line is called the 'line of reflection' Original shape and reflection are mirror images Distance from line stays the same
Grid Paper Reflections
Draw a shape on grid paper Draw a line of reflection Predict where the reflected shape will be Draw your prediction Check with a mirror or tracing paper
Translations: The Mathematical Slide
Translation = slide in a straight line Shape moves but doesn't rotate or flip We describe direction and distance Every point moves the same way
Directions in Te Reo Māori
{"left":"Whakamauī = Left\nWhakamatau = Right\nWhakamua = Forward/Up","right":"Whakamuri = Backward/Down\nRoa = Distance\nTawhiti = Far"}
Shape Sliding Challenge
Use cardboard shapes on your desk Slide shapes in different directions Record: 3 steps right, 2 steps up Work with a partner to give directions Can your partner follow your instructions?
Rotations: The Mathematical Turn
Rotation = turn around a point The point is called the 'center of rotation' We measure turns in degrees 90° = quarter turn, 180° = half turn
