Oral Language
Read the name of the book to your toddler. The concept of counting might be new to him, so you may want to explain what it means, and make predictions about what the book will be about.
You might say:
"Counting means telling how many there are of something. I have ONE nose, and TWO eyes" (point to each and say one, two). "You have 10 fingers and 10 toes. A garden is where fruits, vegetables and flowers grow. I wonder what we will count in the garden in the book."
