Algorithm sequence activity (cut out and order, add flowlines)
Can be used with any year group. Cut out and sort the algorithm, adding in flowlines.
Note: Some children may put 'turn on tap' before 'put bottle under tap', this creates an interesting discussion point, as both algorithms achieve the goal. However, water is not wasted if the bottle is put under the tap before turning it on (Although there will be some clever child who states the tap must run cold first before putting the bottle under!).

Extensions: Get the children to add in their own 'selection' (conditional operators; if, then, else) or decision diamond, e.g. is the bottle full? Yes - turn tap off, no - leave tap on.

This activity is referred to in my online CPD videos: Delve in, for twelve min! See the video attached...
