This courseware focuses on the comparison and ordering of numbers from 11 - 20. First, in the two - number comparison part, it guides learners to describe number relationships using "greater than", "less than", and "not equal to" by counting items like bricks, cakes, pens, and cars, and assigns tasks to find different - gap number pairs. Then, in the three - number comparison and ordering section, it presents various - quantity item sets, asking learners to identify and describe the smallest, largest, and middle numbers in order.
