11. Q. How would you calculate 57 x 6? Q. How would you calculate 5.7 x 6?
Answers please……..
Q. How would you approximate the answer?

12. Look: X
If you find it hard to calculate 0.7 x 6 try counting on in 0.7s and see if your answer is one tenth of 7x6.

13. Complete the worksheet. Work in pairs.
5 minutes

14. Here is a problem:
If 26 children each have a ruler measuring 30cm. and they are arranged end to end to form a line, how long would the line of rulers be?
With a partner think about how you would do this.

15. We would need to do the calculation 30cm x 26.
We can write this as 0.3m. x 26 !
These numbers allow the calculation to be done mentally
i.e
3 x 26 and make it 10 times bigger for 30cm cm
3 x 26 and make it 10 times smaller for m.

16. Try doing the problem if the rulers each measure 32 cm.
Half of you are to work in cm. & the other half in metres.
Remember to approximate first.
Q. Will the answers be the same?

17. 6.3 x 7 = 42.21 Q. Is the answer correct? Has anything gone wrong?
Why?

18. Q. How would you work out the answer ?
6.5 x 4
Q. How would you work out the answer ?
Is there an easier way?
Mentally. the 0.5
