訓練數學感 189 ─ 倒計日

https://4rdp.blogspot.com/2018/10/189.html

今天是九月十四日星期五。十月二十五日，六年級學生會進行第二次升中考試。

Today is September 14^th, Friday. On October 25^th, P6 students will have their second SSPA exam.

老師想做一個倒計日，在週一至週五的時候提醒學生距離考試還有多少天。（例子如下）

SSPA countdown 2 2 Days

Teachers want to make a countdown for students on Monday to Friday, to remind them how many days to the exam (as the following example).

每張A4紙只印一個數字。One whole A4-size paper is used to print only one digit.

孫老師最少一共需要用多少張紙？怎樣印？

How many pieces of paper, at least, does Mr. Sun need to use? How to print?

#	0	1	2	3	4	5	6	7	8	9
pieces need

這題也是香港孫老師的考題，想想看怎樣可以印最少張。
