Answer these questions on your whiteboards. What is: 27 + 14 ?

Answer these questions on your whiteboards. What is: 37 + 24 ?

Answer these questions on your whiteboards. What is: 15 - 7 ?

Answer these questions on your whiteboards. What is: 25 - 7 ?

Answer these questions on your whiteboards. What is: 65 - 7 ?

Answer these questions on your whiteboards. What is: 65 - 17 ?

Answer these questions on your whiteboards. What is: 75 - 27 ?

Answer these questions on your whiteboards. What is: 48 + 26 ? How did you work this one out? Lets look at some different strategies that you used.

Now try these on your whiteboards, you have 2 minutes to work them out. 23 + 45 =45 – 26 = 56 + 32 =87 – 63 = 69 + 28 =58 – 39 = 71 + 26 =66 – 52 = Did any of these cause difficulty?

Lets label the walls of the class N, S, E and W. Stand facing north Turn to face east, south and then west. Did you turn clockwise or anticlockwise? Remember that a clockwise turn is to the right like the hands of a clock.

Stand facing north again. Make a quarter turn to face south. Did you turn clockwise or anticlockwise? Remember that a quarter turn is a right-angled turn.

Stand facing north again. Make a half turn clockwise. Which direction are you facing? Turn to face west. What sort of turn did you make? Face north and turn clockwise through half a right angle. Does anyone know which direction you are facing now?

Halfway between north and east is called north-east. What is half-way between north and west? North-west What is halfway between east and south? South-east What is halfway between south and west? South-west

Turn two anti-clockwise through two-right angles. In which direction are you facing now?

N E S W NE SESW NW Who thinks that they could label this compass? Copy and complete the compass in your books.
