A great addition to any maths lesson. The boxed sets also come with 20 counters, a dice and spinners. The six games in this set are: Place Value to 100, addition (sum>20), subtraction (sum >20), multiplication (by 2,3,4,5,10), division (by 1,2,3,4,5,10) and time (12 and 24 hour). Made from heavy board, each game measures 42cm x 30cm and can be played in groups of 2 to 6 students.
