49. DISCUSS!!! What is ROUNDING?
What do we mean by ‘round up’ and ‘round down’?
Can you think of some examples of when you have seen rounding before?

50. We do not need to know the exact number for everything.
Why do we use rounding?
THINK!
We do not need to know the exact number for everything.
Can you think of any other examples of numbers from everyday that have probably been rounded?
Why not just 7 billion…
There are exactly
6,970,442,289 people on
planet Earth
Teacher Notes:
Class discussion – pupils may have more ideas but key point here is that rounded values are easier to work with in practical contexts.

51. What sorts of things do we round?
Teacher Notes:
The globe with the people represents population.
This slide can be used as a brainstorming activity, using the triggers after students have come up with their own ideas.

52. 50 40 43 Rounding to the nearest 10
43 is closer to 40 than to 50.
Teacher Notes:
Discuss rounding UP and DOWN as rounding to the ten, hundred or thousand closest to the original number.
Language of ROUNDING DOWN can be confusing – what does this actually mean?
Which two TENS does the number 43 lie between?
Where would you place 43 on the washing line?
So, 43 rounded to the nearest 10 is 40.

53. Rounding to the nearest 10
190
180
186
186 is closer to 190 than to 180.
Teacher Notes:
Even though our number now includes place value column of HUNDREDS, we are only rounding to nearest TEN.
Which two TENS does the number 186 lie between?
Where would you place 186 on the washing line?
So, 186 rounded to the nearest 10 is 190.

54. But the rule is… 5 or more, round up
Rounding to the nearest 10 20 10 15
15 is exactly halfway!
But the rule is… 5 or more, round up
Teacher Notes:
Discuss convention of rounding – even though 5 represents half-way, we round UP.
Which two TENS does the number 15 lie between?
Where would you place 15 on the washing line?
So, 15 rounded to the nearest 10 is 20.
