Working out the difference between clockwise and anticlockwise can be very tricky for young children -  they have enough problems working out left and right! Nevertheless these terms are introduced in Year 2. Probably the best way to approach this is to show the movement with the hands of a clock and then to practice making quarter turns clockwise and anticlockwise, holding out one arm to point in the direction faced. There are also a number of games that can be played such as blindfolding a person and asking them  to move a number of steps forward and then turning to reach a particular point. (You need to trust the person giving the instructions!) Go to clockwise and anticlockwise
