This resource is a remix from Illustrative Mathematics https://tasks.illustrativemathematics.org/content-standards/tasks/1081. Suggested Modifications: It is imperative that students in their early ages of mathematics education be introduced to the idea of the number line that makes sense. In other words, they usually count the tick marks on the number line which leads to an inaccuracy in the algorithm. To help them better understand number lines, the suggestion is to introduce the idea number paths which is another way of looking at a number line. To help better facilitate the lesson, I have added a downloadable document student activity that can be used in cooperative learning groups to facilitate mathematical discourse. This activity also encourages literacy in the curriculum.   

Learn about a variety of more "unusual species" treated at the Wildlife Center. The Center typically admits more than 150 different species each year -- while most of these animals are often the birds, mammals, and reptiles whose homes are in and around our own backyards and neighborhoods, Center staff are always prepared for any animal that might come through the door, even if we only see that species once every year or so!  When the Center admits an unusual or uncommon species of wildlife, the staff relies on their extensive knowledge of natural history, as well as creativity and resourcefulness. Some unusual species treated at the Center are rarely admitted due to their secretive lifestyle; some are uncommon admissions because, as a species, they are in trouble.
