![]() Students will be given positive and negative integers. The important part here is just to show them how to use the arrows and the number line itself. You can do this without getting into the math yet. I model a couple of examples and have the students follow along. We take a few minutes to just establish how to use the number line. I start the discovery lab with a workmat that has a number line on it (see the pic below). The best part is that they have to write rules, in their own words, to explain what is happening. The additive inverse discovery lab that I’ll walk you through here does a great job of giving students a concrete view of what is happening when they are adding and subtracting integers. I find that using number lines as much as possible is a great cornerstone for the building of the conceptual understanding when working with integers. It feels like you’re breaking down a wall and then rebuilding it. Getting past this strong built-in understanding can take a while. I’ve even found that many teachers have the same rigidity when it comes to adding and subtracting integers. That’s great! The flip side of that is that you have to work hard to break that schema so that they’ll understand negative integers. Students have a very strong background in positive integers. Through all of my experiences teaching about adding integers there is something that’s always true. Today I’ll share with you how my students get introduced to adding positive and negative integers through a discovery lab approach. Then, when you start the teaching and modeling, they have a place in their brain to put that new information. Discovery labs are an ideal way to start a new topic because it helps students build their own conceptual model right from the get-go. Why? Well, these activities help students face their misconceptions head on. One of my favorite ways to introduce new topics is with a discovery lab. All of these marks are common in Red Foxes.Working with positive and negative integers is something that can throw students off at first. The Gray Fox and the Coyote do not have a white tip on their tail or black feet, legs, underside of tail, and ear edges. The trapping/hunting season for the Red Fox in Georgia runs from December to mid-February. In the west it avoids desert and high plains habitats. It now ranges over most of the eastern and inter-mountain western United States. This species was introduced into many areas of the eastern and southeastern United States by the early 20th century. ![]() The Red Fox inhabits all of Georgia except the lowest portions of the Atlantic Coastal Plain. This species is susceptible to several infectious diseases, including mange, distemper, and rabies. The average life span of the Red Fox is 4 - 5 years, but individuals have lived in captivity for as long as 8 years. Most foxes maintain a home range of 8 - 10 square kilometers (3.1 - 3.9 square miles). Dens are usually located in areas of loose soil on hillsides under cover of heavy brush or shrubs. Dens may be dug by the foxes themselves or may be enlarged burrows dug by other small mammals. Red Foxes maintain dens in which to retreat during daylight hours and bad weather, as well as to rear young. ![]() It will also consume fruits, berries, insects, and occasionally carrion. The majority of its diet consists of rodents, rabbits, and other small mammals. It also inhabits forest edges, river bottomlands, and rocky hillsides. This species prefers to live in areas of mixed pine-hardwood forests interspersed with fields and cropland. Primarily nocturnal in the summer, the Red Fox is more active in daylight hours in the fall and winter. Young reach sexual maturity at 10 - 12 months of age. They are about 6 months old at this time. The young remain with the parents until autumn, at which time they disperse. Pups are weaned at 8 - 10 weeks, and begin to accompany the parents on hunting trips by 10 weeks of age. The male provides food for the female and young while the pups are still at the den. The helpless pups grow rapidly and begin to be able to leave the den at about 4 weeks of age. An average of 4 - 5 young are born after a gestation period of about 52 days. Red Foxes are monogamous and breed in January and February. The Red Fox ranges from 90 - 114 cm (35.4 - 44.9 in) in total length and weighs 2.7 - 7.7 kg (6 - 17 lbs). The long bushy tail is tipped with white and the feet, legs, underside of tail, and ear edges are black. The head and upper body are generally a deep reddish brown to yellowish red, but black and silver color phases also occur.
