Giraffe Class Maths
Term 6 Week 2 Activities
Fractions: Counting in tenths. Unit and non-unit
fractions. Recognise, find, and
write fractions.
Professor Assessor (about 30 minutes)
• Professor Assessor is really important because it gives your teachers and TAs, as well as yourselves and your parents, the chance to analyse your learning and to track your progress.
• Well done to everyone who completed the Home Learning Activity I set last week, called ‘Geometry’.
• This week, I have set you an Assessment called ‘Number & Place Value 1’ in order to see how much you have remembered of this topic and what we need to revise. Please log in and have a go – you only have one week to complete this!
• Please also spend time practising your Times Tables on the site!
• You were sent home with your login details in your home learning packs. To access the site, please click on the link: https://www.prof123.co.uk/Start. The school code is: BRN
Mathletics (about 30 minutes)
• Just like Professor Assessor, Mathletics is really important because it gives your teachers and TAs, as well as yourselves and your parents, the chance to analyse your learning and to track your progress.
• Last week, I decided to unset all the tasks that had not yet been completed, and set you all some Geometry work on ‘Properties of Shapes’, to match the topic. Well done to those of you who completed these tasks!
• This week, I have set you some work on ‘Number and Place Value’ which will complement the Professor Assessor Assessment!
• Please log in and have a go! • https://www.mathletics.com/uk/
Note to Parents:
• I have decided to include the answers to the questions on each week’s PowerPoint from now on, so that the children can more quickly check and correct their work, for greater learning impact. Therefore, on this PowerPoint, there are – unusually – three sections, instead of the usual two sections: 1. Last Week’s Answers (usual)
2. This Week’s work (explanations and tasks) (usual)
3. This Week’s Answers (new this week)

Last Week: Maths Vocabulary
• Regular: A regular shape has sides, faces and angles of equal size.
• Irregular: An irregular shape which is not regular. An irregular shape has sides, faces or angles of differing sizes.
• Symmetrical: An object is symmetrical when one half is a mirror image of the other half. It may be divided by one or more lines of symmetry.
• Asymmetrical: An object which does not have lines of symmetry. One half is not a mirror reflection of the other.
• Polygon (plural = Polygons): A 2D, plane or flat shape. Polygons may be regular with all sides and angles equal, or irregular with varying side and angle sizes. E.g. Triangle.
• Polyhedron (plural = Polyhedra): A 3D shape. E.g. Triangular Pyramid.

Answers: Task 13: Challenge 3 (15 minutes) Have a go at this challenge! Draw the six shapes into your book, exactly as they are, then colour them, following the instructions.
Answers: Task 14: Challenge 4 (10 minutes): Ruler needed! 1. Draw a rectangle. Each of the long sides must be 6.5cm long. Each
of the short sides must be 2.4cm long. Then calculate the perimeter. You may round each measurement to the nearest whole centimetre. Perimeter = 6.5cm + 6.5cm + 2.4cm + 2.4cm = 17.8cm Rounded = 7cm + 7cm + 2cm + 2cm = 18cm.
2. Draw an isosceles triangle. Each of the long sides must be 8.9cm long. The short side must be 5.5cm long. Then calculate the perimeter. You may round each measurement to the nearest whole centimetre. Perimeter = 8.9cm + 8.9cm + 5.5cm = 23.3cm Rounded = 9cm + 9cm + 6cm = 24cm
3. Draw a regular pentagon. Each of the sides must be 3.2cm long. Then calculate the perimeter. You may round each measurement to the nearest whole centimetre.
Perimeter = 3.2cm x 5 = 16cm Rounded = 3cm x 5 = 15cm
This Week’s Learning Term 6 Week 2
Your Tasks!
Introduction
• This week, we are going to start our new topic of Fractions. • We are going to learn how to:
– count up and down in tenths; – recognise that tenths arise from dividing an object into 10 equal
parts and in dividing one-digit numbers or quantities by 10 – recognise, find and write fractions of a discrete set of objects:
unit fractions and non-unit fractions with small denominators – solve problems that involve all of the above
• Each week, I will also set you a Mental Maths worksheet! • I’d also like you to spend at least half an hour each week on
Professor Assessor and the same on Mathletics. This might be revising topics we have already covered, work on our current topics, or times tables practise. I will set you tasks each week to complete.
Task 1: (20 minutes) Mental Maths! Easier Sheet (See next page for Challenge Sheet – choose which one you’d like to do!)
Task 1: (20 minutes) Mental Maths! Challenge Sheet (See previous page for Easier Sheet – choose which one you’d like to do!)
Task 2: Addition Questions
(10 minutes)
Make sure you are keeping your addition
skills sharp!
Practise adding one, ten, and one hundred.
For the last few
questions, you will need to use your subtracting
skills too.
Fractions
• Watch this video on the school YouTube channel as an introduction to our fractions work this week:
• https://www.youtube.com/watch?v=G15yzu-Gjuc
• To be clear: the diagrams here are hand drawn to aid my own recall and understanding, which is a good technique for you to also use, but each fraction/piece is therefore not identical.

Fractions Explained Further:
• A unit fraction is any fraction where the numerator is 1, e.g. ¼.
• A non-unit fraction is a fraction where the numerator is not 1, e.g. ⅘.
• Mixed fractions are a mix of whole numbers and a fraction together, e.g. 1 ¼.
Fractions Explained Further:
• Watch this short video, then do the check activities and the quiz:

Unit Fractions:
Unit fractions are where the numerator is 1. They are one part of the whole. e.g. I have an orange. I divide it into the segments. There are 7 segments altogether. Therefore, each segment is 1/7.
Here are some more examples of unit fractions:
Non-unit Fractions:
Non-unit fractions are where the numerator is not 1. They are more than one part of the whole. e.g. I have an orange. I divide it into the segments. There are 7 segments altogether. I eat 3 segments. Therefore, the fraction of the orange that I eat is 3/7.
Here are some more examples of non- unit fractions:

Year 3 Count up and down in tenths
• Watch this short video and practise counting in tenths:
• https://www.youtube.com/watch?v=slnc11A_LiU
This is a really useful diagram to show what one
tenth is.
Fractions are used in different ways.
For example, we
might say approximately 1/3
of the class are boys.
Or we might say
the desk measures 1.7 metres. (one
and seven tenths).
Or we might say the shop is
offering 10% off (one tenth).
Task 6: Counting in Tenths (10 minutes)
• Use the image below to practise counting up and down in tenths. Tenths are when we divide or share out a whole into ten equal parts. e.g. If I had ten sweets, and I gave you two sweets, then you would have 2/10 (two tenths). I would have 8/10 (eight tenths) left.
• Up: zero, one tenth, two tenths, three tenths, four tenths, five tenths, six tenths, seven tenths, eight tenths, nine tenths, one whole! (One whole = ten tenths, but we say one whole).
• Down: one whole, nine tenths, eight tenths, seven tenths, six tenths, five tenths, four tenths, three tenths, two tenths, one tenth, zero.
• How many times can you count up and then back down again in one minute?!
Task 6 (continued): (10 minutes) Counting in Tenths Practise counting up and down in decimals.
(e.g. zero, zero point one, zero point two, etc.)
How many times can you count up and down from zero to one in one minute?!
Can you count up to two?
(e.g. one point one (1.1), one point two (1.2), etc.)
Task 7: Counting in Tenths (10 minutes)
• Can you fill in the sequence? Copy it into your book and fill in the gaps. Then have a go at the bottom test. The first one has been done for you.
• Challenge: can you write it backwards?

Mixed Numbers
• Mixed numbers
• A mixed number is made up of a whole number and a fraction, like in the examples below. It is where you have a mixture of whole numbers and fractions.
Task 12: (10 minutes)
Counting in tenths – Challenge Activity
How many tenths are
there?
Some of these are fractions, and some are mixed numbers.
Don’t forget that ten tenths (10/10) is one
whole (1).
e.g. Number 12: 3 wholes and 4/10.
Task 13:
(10 minutes)
Write the shaded part of the shape
as a decimal.
It might help you to write it as a fraction first.
e.g. Number 1 (done for you):
2/10 are shaded (two tenths), so
the decimal is 0.2.

How many tenths are
there?
Some of these are fractions, and some are mixed numbers
Don’t forget that ten tenths (10/10) is one
whole (1).
e.g. Number 12: 3 and 4/10.
1. 5/10 2. 3/10 3. 7/10 4. 1 and 1/10 5. 3 and 8/10 6. 1 and 4/10 7. 1 and 6/10 8. 1 and 2/10 9. 1 and 9/10 10. 6/10 11. 2 and 3/10 12. 3 and 4/10 13. 3 and 8/10 14. 7 and 5/10
Note: these should not be written with the ‘and’, and the fractions should be one number over the other with a horizontal line – my computer prevents me!
