[00:00.00]Unit 3 Please show me how to do this sum
[00:05.88]A Let's read
[00:09.85]Peter,Sue and Anne were in the craft class.
[00:14.99]Mr Wu,the craft teacher, told the children how to improve their craft work.
[00:22.15]"You must make a proper plan before you start,"he said.
[00:27.92]"This is how you do it.
[00:31.58]Draw a picture of your object on a piece of paper
[00:37.15]and write the measurements down.
[00:41.09]If you cut the pieces out correctly,
[00:45.35]you will be able to put them together properly."
[00:49.79]The children began to work.Unfortunately, they were not doing very well.
[00:57.55]They had to ask the craft teacher to help them.
[01:02.20]"Excuse me,Mr Mu," said Peter.
[01:07.19]"Can you show me how to put the sides of my box together?"
[01:13.12]"Certainly,"said Mr Wu
[01:17.77]"Hammer these nails into the sides to hold them together."
[01:23.12]"I'm trying to make a bowl,but the clay is too soft.
[01:29.08]Please show me how to dry the clay." Of course,"said Mr Wu.
[01:36.73]"Add some flour to the mixture.That will dry the clay."
[01:42.90]"I'm making an apron for myself," said Anne.
[01:48.17]"I've got my material and I've measured myself.
[01:53.63]I've written the measurements here.
[01:57.76]Please show me how to do this sum,Mr Mu.
[02:02.80]Then I can finish the plan.
[02:06.64]"First,write down the measurement from your shoulders to your waist.
[02:12.21]Then add it to the measurement from your waist to your kness.
[02:17.53]The answer will be the length of the apron.
[02:22.29]Then measure your waist and divide the length by two.
[02:28.56]The answer will be the width of the apron.
[02:33.21]Write those numbers on your plan."
[02:37.68]"Thank you,Mr Wu,"said Anne.
[02:42.22]Denis Dragon
[02:46.58]Tim was doing his maths homework.
[02:50.42]Denis was bored.
[02:53.66]He was watching Tim.
[02:57.14]"What are you doing, Tim?"
[03:00.48]"I'm doing my maths.I'm multiplying 65 and 73."
[03:07.85]"Can you show me how to do that?"
[03:12.39]"I'm sorry,Denis.It's too difficult.I can't."
[03:18.03]"Please show me Tim.Please."
[03:23.28]"All right Pretend that you've got 65 toes on each foot
[03:31.15]How many toes have you got all together?"
[03:35.22]Denis started to draw a picture of himself with seventy-three feet.
[03:39.66]After a while,he stopped.
[03:43.63]"You're right," said Denis.
[03:47.71]"Maths is too difficult for me."
