Rotating Shapes

What 3 things do you need to say to describe a rotation?
1.Where the centre of the rotation is?
2.How much it has turned through(1/4, or 1/2 turn or an angle)
3.Weather the rotation has turned anticlockwise or clockwise.

Explain what centre of rotation means
The centre of rotation is a little dot or cross on a grid which is where the shape of the rotation should turn on the line where the dot is.

Now use these 3 things to describe the rotation on Page 1 of the myimaths lesson (i.e. describe the rotation of the triangle)


The centre of this triangle is at 1,1 on the grid. It has turned 90ยบ or 1/4 and has turned clockwise.

Maths Rotation Task

 



How To Multiply Fractions


Step 1: If you have a fraction like this 6/4  x  8/4   you need to....
Step 2: You need to multiply the two top numbers together 6x8= 48. 
Step 3 : Then multiply the bottom numbers which are 4 x 4= 16.
Step 4 : so the answer would be 48/16 but then you need to simplify. 
Step 5 :  Then simplify so it would be 12/4 and there is your answer .

This is what the working out should look like.
