A set of loop cards using subtraction skills to find change from 20p. Subtraction uses numbers up to 10p.
Simply cut and laminate the cards, divide between a small group/pairs/individual, they find the 'start' card and read the number sentence, solving gives them the next card, continue until all the cards form a loop to 'end'.
Also available to 10p, 50p and 1 pound.
