Millennium Bridge                                        Maths Lesson Plan A

Year/Class: Y5/6

Numeracy: 
Read and plot co ordinates in all four quadrants and state where a shape will be after translation.

Mental / Oral Teaching Objectives:
Recognise and extend number sequences through both positive and negative integers

Resources
Number line   Whiteboards / pens

Mental / Oral Activities

Introduce both vertical and horizontal number lines.

Work from –15 to +15

Play number chain game.

Start from a fixed point and give a series of number computations. Children write down where on the number line they should now be.

Key Vocabulary

Positive / Negative

Number line

Add

Subtract

Key Questions

Start at 6 on the number line. Add 5 take away 8

Subtract 3

Where on the number line are we now?

Start at  -12

Give me three commands to take me to plus 7

Main Teaching Objectives
Introduce the concept of translation as a glide without rotation / reflection across four quadrants and to describe movement using x and y co ordinates.

Resources
Acetate overheads: 4 quadrants, 4 quadrants + river, acetate with river and flags, Millennium Bridge template, Pupils recording grid.

Main Activities.

Children identify main co ordinates in first quadrant.

Progress on to all four quadrants.

Introduce Millennium Bridge template. Fix it onto illuminated quadrant grid on teacher whiteboard.

Point out three co ordinates x  y  z? (stay in first quadrant to start with)

Record them.

Ask pupils to show where the shape would be after the translation 2 squares to the right.

Record the new co ordinates underneath previous ones.

Repeat task moving vertically and horizontally always drawing attention to co ordinates before and after translation.

Give two co ordinates of the bridge and they have to find the third.

Work in pairs to plot ‘bridge’ by giving them initial co ordinates and then translating

          2 squares to the left

          1 square down 3 to the left

          2 squares to the right and three up

Where would they be after four moves?

Predict then check.

Millennium Bridge task

Children given a 4 quad grid with route of River Tyne running through all 4 quads. Can the children glide the bridge through all 4 quadrants stopping in each one so that the horizontal movement is repeated

Key Questions

What do you notice about the x/y co ordinate after translation?

Where will the bridge be after the translation two squares to the left?

What do we need to change to move vertically?

What will happen to both co ordinates if we move diagonally?

Key Vocabulary

Translation

Co ordinates

Vertices

X and y axis

Vertical

Horizontal

Plus

Minus

Less Able

Remain in first quadrant for translation

Use template. Use A3 Grid.

More able

All 4 quadrants

Translate without template.

Put flags on designated overhead acetate of the River Tyne.

Children have to explain and prove translation.
