'Times Tables Shifts' printed from http://nrich.maths.org/
The numbers in the five times table are:
5, 10, 15, 20, 25 ...
I could shift these numbers up by 3 and they would become:
8, 13, 18, 23, 28 ...
In this activity, the computer chooses a times table and shifts it.
Can you work out the table and the shift each time?
Can you explain how
you worked out the table and shift each time, and why your method will always work?
Level 1 includes tables up to 10.
Levels 2 and 3 include tables up to 20.
On levels 1 and 2, the numbers will always be the first five numbers in the times table.
On level 3, the numbers could be any five numbers from the shifted times table.
