Transcript of This week, you will review and practise your fractions ...…This week, you will review and practise...
Hello everybody, I hope you are all well!
This week, you will review and practise your fractions. You
also have daily arithmetic tasks, remember you have 5
minutes to answer as many questions as you can, then check
the answers. Each day, try to beat you personal best!
Then, go through the PowerPoint to refresh your knowledge
and understanding of fractions, then complete the daily tasks
and remember to check your answers and find the reason
for any mistake.
Once again, on Friday you will do a fractions test to check
your learning.
Monday:
Today, we will start reviewing fractions and we
will look at what each part means.
You will also order and compare fractions with
the same denominator.

Remember: a proper fraction is less than a whole
number. Think of a cake. Half a cake is less than a whole cake.
Half a cake is just a part, or a fraction of the whole cake.

Numerator
Denominator
The numerator tells you how many parts are in our fraction.
The denominator tells us how many the whole has been divided into.

Tuesday:
Today, we continue reviewing fractions and we
will look at equivalent fractions – that is 2
fractions which represent the same part of a
whole.
Remember: you either MULTIPLY or DIVIDE
and what you do the NUMERATOR you MUST
do to the DENOMINATOR!

TUESDAY TASKS:
Wednesday:
Today, we continue reviewing fractions and we
will look at adding and subtracting fractions. Do
you remember what happens to the
denominator? Why?
We will also look at proper and improper
fractions. What do you remember?

Wednesday task 1
Challenge:
As I am sure you remember, an improper fraction is a fractions where the numerator is
larger than the denominator, therefor the fraction is larger than 1. Improper fractions
can also be shown as mixed numbers.
Try this, use these digit cards to make five
fractions that are greater than one.
Write your fractions in two ways.
3 1 4 11 2 8
Use these digit cards to make five fractions
that are greater than one.
Write your fractions in two ways.
3 1 4 11 2 8
For example:
4 1 11 1 8 8 2
3 3 2 2 4 3 3= 1 = 5 = 2 = 2
Now try this: what are the next two numbers in
each sequence? Can you express each as an
improper fraction and a mixed number.

Thursday:
Today, we will revisit finding fractions of
amounts. Do you remember what happens to
the whole? Which number do you divide by?
We will also look at unitary and non-unitary
fractions.
ArithmeticArithmetic
Q1 384 + 30 = Q6 ___ + 700 = 1084
Q2 246 – 138 = Q7 __ = 18 x 4

So, now you remember!
For unitary fraction (the fraction where the
numerator is 1), you divide the whole amount
by the denominator to find the answer.
For non-unitary fractions, you divide the whole
by the denominator and then multiply the
answer by the numerator.
