I used to think that the way to count time was to sound it out slowly. e.g. Once my Mum said to wait five minutes so i said f-i-v-e m-i-n-u-t-e-s out loud and really slowly and thought that meant five minutes was up.
Because of this I could never understand how one hour was longer than say twenty minutes because when you say it out loud twent minutes would be longer.
