See above ten phrases which need to be memorised. Each time the blue play button is clicked a phrase will be removed from the collection. The aim of the activity is to write down the exact the phrase after it has been removed. After the last phrase has been removed all ten phrases are then shown in the order they were removed so that accuracy can be checked. The auto play button removes phrases at thirty second intervals (the time interval can be changed  see below).
