Starter Activity
Ask each pupil to write down a number on their mini whiteboard as they come into
the classroom.
Have a < sign either on the interactive whiteboard or on a mini whiteboard at the
front of the classroom.
Call pupils up in pairs and ask them to position themselves either side of the < sign.
Pupils must give their reasons.
Then ask other pupils to join in creating a chain of pupils either side of the sign.
Ask pupils what would happen if the sign was reversed and became a > sign.
If none of the pupils have negative numbers written on their whiteboards ask a
child to hold a zero and position them with the < sign. Ask pupils if they can write a
number on their board which will enable them to position themselves on the other
side of the < sign.
Ask everyone to sit down and then position two pupils with positive consecutive
integers, either side of the < sign.
Ask the class if they can write a number on their mini white board which will
enable them to position themselves between these two pupils.
(If all of the suggestions are decimal numbers ask pupils to think about what they
could use instead of a decimal, leading them to consider fractions.)
Change the positive consecutive integers into negative numbers and ask the class
what difference this makes.
Main Activity
Task One –
Ask pupils to choose 4 sets of numbers, sets A – D are positive and negative
integers, sets E – H also include decimals and fractions.
Explain to pupils that they should work collaboratively to decide which of the 4
sets of numbers has been arranged from largest to smallest.
They should use the number lines provided to help them to do this.
Task Two –
Ask pupils to choose one of the three Greater Than or Less Than Challenges. They
can choose either to work just with integers, or with decimals. Pupils should use
the numbers and symbols provided to write number sentences. Ask pupils to
consider whether it is possible to find them all and what strategies they are going
to use? For students that are struggling, replace the symbols with the words
greater than and less than.
Plenary
Invite pairs of pupils to share their strategies with the rest of the class.
