Aims and objectives
The pupils will be able to order numbers to 20 and position them
on a number grid.
Previous knowledge
The pupils can read and write numbers to 20. They can count on and back
in ones. They are familiar with some of the vocabulary used in comparing
and ordering numbers.
In the classroom
The pupils are given a 5 by 4 number grid with numbers
to 20 written in. One by one, a number card appears. The
pupils have to drag this card and drop it onto the matching number
in the grid. If they make a mistake, the card snaps back and
they have another go. When the grid is complete, the pupils
receive praise.
In the next part of the activity, pupils are given the same
5 by 4 grid. This time the numbers are missing. One
by one the number cards appear and the pupils drag them to the
correct position on the grid. Even pupils well used to positioning
numbers on a number track will find this task tricky. Try
it for yourself!
The pupils score is shown at the end of the activity. The
higher the score, the more praise the pupil receives.
If the school has access to an interactive whiteboard then this activity
is perfect for whole class teaching. The teacher can call out pupils
to drag and drop the numbers into the grid to complete the number
track. This approach can also be used to encourage children to talk
about the activity and describe their decisions, reinforcing their
vocabulary.

Resource type: |
| The first worksheet is more of a tool for the teacher than a worksheet for the pupil. The
grids can form the basis of teacher made worksheets or they can be photocopied and given to pupils as
part of a whole class mental maths game. |

| The second worksheet extends the task by using grids of different shapes. The
pupils have to fill in the numbers that are missing. Again, this is far more tricky than
positioning numbers on a number track. More able pupils can make grids of their own, perhaps with numbers
up to 100. |
Missing_numbers_20.pdf |
| The third worksheet moves away from the grids and asks pupils to compare and order
sets of given numbers. Asking the pupils to use the same skills in a different way provides
the teacher with an excellent method of assessment. |
