Stage 1 learners grasped a new skill called subitizing- how to recognize the number of objects presented in familiar patterns without counting, by using the Hungarian Frame of 10. After a number was called randomly, children used the counters made with clay dough to arrange them on the number frame. This activity helped them to develop an understanding of how a number is made up: for example, seven dots could be a set of three dots and a set of four dots or a set of six dots and one dot. This understanding of part-part-whole relationships helped them to separate and combine numbers and accelerated their understanding of addition and subtraction.
