Counters 2 Colour 25mm – 200 piece in Jar
$15.95 inc GST
Two-coloured counters feature one yellow side and one red side on the reverse. Use them for addition, subtraction and also many more activities. The set comes in a pack of 200 pieces while measuring 25mm in diameter. Some activity ideas for bi-coloured counters: Use the two colours of the counter to practise with positive and negative numbers. For instance: positive is yellow and negative is red. -2 3 would mean that you have 2 yellow and 3 red counters. A single positive and a single negative counter represents a sum of 0, and can therefore be ‘cancelled out’. What is left is one red counter. Students can now visualise that the answer to the equation is 1.
