Use things around the house that they already know and love! : My son has a HUGE adoration for his Thomas Trains... he can tell you every single trains name, number and color. When we started working on recognizing numbers and colors, I tried to use posters, games, workbooks, etc that would help him learn to recognize them... all to no avail! One day, we were playing with his trains, and HE asked me what number one of the trains was. Bells went off in my head and I realized that I could cater his natural curiosity about his beloved trains, and still be 'teaching' him to recognize numbers at the same time!
School administrators are responsible for choosing the type of curriculum taught to children. As long as they are learning, the curriculum is considered effective. Using computer games as a tool is one option available to today's schools.
Go on a counting scavenger hunt! For young children, you can keep the hunt simple and indoors, go on a hunt and count how many bedrooms, windows, doors, bathrooms, etc are in your house. For older children, you can even take this adventure outside. Look for certain kinds of animals, plants, flowers, you name it! Add in another element of fun (for any age) and create a graph for them to track their finds!
In addition to mental math activities, children should be given grade level mathematics workbooks to strengthen their math skills. Parents should have these books and other subject content books at home for additional practice and homework. These can be purchased from bookstores, teacher supply stores and multiple-purpose department stores where school or office supplies are sold.
