A set of cards designed to strengthen the understanding of<\/strong> quantity<\/strong>, a fundamental prerequisite for learning calculation skills. The different visual representations of quantities—shown as hands, dots, objects and block towers<\/strong>—help children develop effective quantification strategies by making use of their innate ability to recognise small quantities at a glance.<\/p>\n
