You may choose to begin this study with a unit on dinosaurs, always of interest to children, before proceeding to mammals. Stick as much as possible to North American mammals, rather than those elsewhere in the world. Start with the most primitive order (marsupials) that occur in North America and continue to those generally considered most advanced. However, you should include animals from other continents, often found in many zoos, that particularly interest children, such as the giant pandas of Asia, carnivores and pachyderms of Africa and India, perissodactlys (tapers, rhinoceroses, zebras) artiodactyls (hippopotamuses, camels, giraffes), and primates of the Old and New Worlds. Allow one week for each order.

Ten pages cover birds, geology, human body, insects, machines and inventions, mammals, reptiles and amphibians, space and astronomy, water, weather and winds.

Eight mathematical questions; example: MR. L. lasted 321 days on the job before he was fired. What percentage of a year did he serve?

Challenge your children or students, while slipping in big doses of cultural literacy and reinforcing basic skills. Use this approach to enrich current studies, to extend students' literacy, and to supply impetus for students to recite poetry, to master difficult spelling words, and whatever else you want them to accomplish but which students might say, "That's too hard!" Memorizing poems not only provides an outlet for the academic energies of the students who attempt them but also increases their memorization skills. These thirty-one poems provide opportunities to reinforce students' knowledge of the effects of sound (alliteration, onomatopoeia, or rhyme schemes) and those of personification, metaphor, simile, and hyperbole.

Emphasis on opening everyone's eyes and senses to our surroundings from automobile and sports team names to other parts of our man-made environments' multitude of shapes from water towers to and most especially "The language of buildings." This "language" awakens and deciphers: roof styles, uprights (columns, pilasters, etc.), entablatures, entrances, windows, decorative features, brick types. Fun for classroom students and families.

An educational outing for individual children or groups. Plan a half-hour "sit" on a grassy hill adjacent to a busy highway or in a building that looks out over a highway for the purpose of providing participants with counting and graphing exercises, working with percentages, researching, learning new words-and having fun! Children learn to tally cars' different colors, total number of vehicles recorded, compute the percentage of the total each color represents, Follow-ups include learning the proper names of every sort of vehicle, researching vehicles in other countries (Wohnmobil, autocaravana, rickshaw, etc.), figuring percentages of various trucks to other vehicles, taking "field trips" to RV showrooms or trailer parks, and mastering the language of vehicles from axle through SUV.
