Aims and objectives
Pupils will understand and use the vocabulary of comparing and
ordering numbers. They will develop problem solving skills
and begin to reason about numbers up to 10.
Previous knowledge
Pupils can count to 10. They can to count on and
back in ones. They can order numbers to 10 and they have some
understanding of the vocabulary involved.
In the classroom
The pupil is asked to type in a number between 1 and 10. Depending
on the number they have typed in, the pupil is told whether their
guess was too low or too high. The pupil can guess as
many times as they like but the number of guesses is recorded. The
pupil is then motivated to find the number in as few guesses
as possible.
The activity is intended to be used as a short Numeracy game rather
than the content of a lesson. For this reason there are no
supporting materials. However, because the game is likely
to prove to be popular amongst pupils, why not have a whole class
game during a mental maths session? Using an interactive whiteboard,
pupils can try and guess the number and take it in turns to touch
the screen and announce the results to the rest of the class.
Curriculum references
Foundation Stage – Early Learning Goals:
 Say and use the number names in order in familiar contexts
 Count reliably up to 10 everyday objects
 Recognise numerals 1 to 9
 Use language such as more or less, greater or smaller, heavier
or lighter, to compare two numbers or qualities
 In practical activities and discussion, begin to use the vocabulary
involved in adding and subtracting
 Use developing mathematical ideas and methods to solve practical
problems
Key Stage 1  Numeracy Strategy:
 Use mental strategies to solve simple problems using counting,
addition, subtraction, doubling, halving, explaining methods
and reasoning orally
 Know by heart all addition and subtraction facts for each number
to at least 10
 Know and use halving as the inverse of doubling
