You won't find activities in this book on how to weave baskets or design chessboards with children. I was never able to rush out for Popsicle sticks or other special arts and crafts items after a day at work. I needed activities that could be done alongside my household routines, using whatever I had at home. Not every parent is a born teacher. It makes sense that what works for pre-schoolers won't work for fifth grades.
Parents have to be ready to change gears as children grow.
These are not hard and fast age and grade distinctions. Use all and any of the activities that appeal to you and your child. I indicate ages only to provide some guidance for selecting activities. I hope that all of the activities in whole or in part will be useful to everyone. Providing activities that span the age ranges is a challenge.
