Often this is a difficult concept as there are are 3-4 numbers at anyone time and pupils get confused. One way to make sure that pupils are sure of the smallest/biggest number.
For instance, for the question on arranging the numbers from the smallest to biggest,
1)Ask the pupils to read the question.
2) Ask them to ask themselves which is the smallest number. Each time they write a number down, cancel the number.
3) Then ask them to ask, which is the smallest number now and repeate the process in step 2.
Arranging numbers from the Smallest to Greatest
1) Use a rhyme like 10 Little Indian Boys http://www.youtube.com/watch?v=5IO24dCmxk0
2)Ask pupils to arrange the numbers from the smallest as they sing the song.
Arranging the numbers from the Greatest to smallest
1) A video from http://www.youtube.com/watch?v=Z1sCuNEZkCE enables pupils to see the numbers becoming smaller.
2) Pupils were also taught to sing using their fingers and to fold them as the number decreases.
3) Pupils count the numbers backward as they arrange the number.
Ask your child for a demo. I am sure they remember their lesson learnt on Friday
Meanwhile do practice. These websites are a great source.
