Year 6 Coordinates, Reflection and Translation: lesson and practice

By the end of this chapter you will be able to

• Write the coordinates of a point in any of the four quadrants, using negative numbers, across first
• Name the quadrant of a point, and explain why a point on an axis is in no quadrant
• Plot points and draw a shape from its corners, and find the length of a side along a grid line
• Find the missing corner of a rectangle from three of its corners
• Translate a point or a shape on the coordinate plane, and describe a translation in words
• Reflect a point or a shape in the x-axis and in the y-axis
• Explain that a translation or a reflection keeps the size and shape of a shape

You should already know

• Negative numbers, counting through zero on a number line (Year 5, Chapter 1; Year 6, Chapter 1)
• Position and direction on a grid, and coordinates in the first quadrant (Year 4, Chapter 10)
• Translations and reflections in a mirror line on a grid (Year 5, Chapter 10)
• Perimeter and area of rectangles (Year 5, Chapter 8)

Where this leads

• Reflecting shapes in lines other than the axes, and coordinates in more complex shapes (KS3)
• Statistics: pie charts, line graphs and the mean (Year 6, Chapter 12)
