When i teach numbers and alphabet for my kid, i don't want to teach him just numbers. It is bore for them. I want to do something out of box. When i was looking for option, i have ended up with this idea. Use numbers to draw some objects.
Drawing animals / flowers / birds using numbers helps the child to recognize and remember / recollect it easily. It brings their interest in learning and they will be excited learning also. It helps them learn numbers, drawing, names of the objects. It is multipurpose activity for kids.
