Year 1 Read, write numbers to 100
Year 1 performance descriptor: Read, write (numerals) and represent using models images,
numbers to 100.
Notes and guidance (non-statutory): Pupils begin to recognise place value in numbers beyond 20
by reading, writing, counting and comparing numbers up to 100, supported by objects and pictorial
representations.
Children played an online game where they needed
to locate the given number on the 100 square under
time pressure. They read the target number before
they looked for it on the 100 square. Once they had
found and clicked on the number, the computer told
them how many seconds they had taken to find the
number.
Emily was able to read all the numbers up to 100
and found them as quickly as she could by, ‘looking
at the tens and going along the line.’
Emily also played ‘Mend the Hundred Square,’
which required her to read the numbers and place
them back in the correct place. Emily explained she
knew where the number went by looking at the
number before and the number after in a row.
Children were given a range of equipment including Dienes rods, Numicon, place value cards and
beads strings and were asked to make a number in as many different ways as they could using the
equipment.

Emma made numbers such as 35 and 76 confidently with a range of different resources. She
exhibited a secure understanding of the place value of two digit numbers as she counted 7 tens on
the bead string and then 6 single beads, 7 ‘tens’ rods and 6 ‘ones’ cubes and so on. She counted
carefully twice each time to check she had the right number.
To extend her skills, Emily was asked to
count forwards and back to complete the
missing circles on the number snake.
Emily also spotted on some of the snakes,
the sequence of counting forwards or back
was incorrect.
She was able to correct the number
sequence.
