Presentation Transcript

Slide 1: 

Translations = Slides

Slide 2: 

Translations move a shape to a new position without changing the original shape. Translation movements are described with VECTORS

Slide 3: 

Translation movements are described with VECTORS The VECTOR has two numbers in a column: 8 4 1 2 3 4 5 6 7 8 The top number is the movement to the RIGHT The shape moves 8 squares to the right

Slide 4: 

Translation movements are described with VECTORS The VECTOR has two numbers in a column: The bottom number is the movement UP The shape moves 4 squares up 8 4 1 2 3 4 5 6 7 8 4 3 2 1

Slide 5: 

To find the vector, choose ANY point & count to the same point on the translated shape. Always count the horizontal distance first & count “corner to corner” The vector is written inside brackets WITHOUT a fraction line 1 2 3 4 5 6 7 8 4 3 2 1

Slide 6: 

Movement to the LEFT is a NEGATIVE number Always count the horizontal distance first & count “corner to corner” The shape has been translated 14 13 12 11 10 9 8 7 6 5 4 3 2 1 1 2 3 Movement DOWN is a NEGATIVE number

Slide 7: 

Always count the horizontal distance first & count “corner to corner” The shape has been translated 14 13 12 11 10 9 8 7 6 5 4 3 2 1 5 4 3 2 1

Slide 8: 

Translations are “slides” The shape doesn’t change Choose 1 point to count from (& the same point to count to on the translated shape) Count “corner to corner” horizontally first Then count vertically

Slide 9: 

Translations are written as VECTORS The top number is right, a negative number is left The bottom number is up, a negative number is down Write the numbers vertically in brackets (no ? line)

Slide 10:
