Exploring Addition of Three Whole Numbers

In this video, we learn how to add numbers up to 20 by helping Irene count items in her house. We start in the kitchen, counting apples, oranges, and strawberries to find a total of 13 fruits. Next, we move to Irene's room to add toy cars, dolls, and balls, totaling 15 toys. Finally, we head to the backyard to count yellow and pink flowers, and then add new red flowers, resulting in 17 flowers. This tutorial provides a practical approach to addition using everyday objects.
