The product of a Special Studies Institute, this teacher developed resource guide for the emotionally handicapped (K-6) presents 37 activities designed to develop mathematics concepts and skills utilizing the urban out-of-doors. Focus is on experiencing math models, patterns, problems, and relationships found in an urban environment. Activities are numbered, and each activity is correlated with one of six specific mathematical concepts and/or skills. Listed below are the six topics and examples of corresponding activities: (1) Sets, Numbers, and Numeration--e.g.; Take a 10 minute walk. Keep a record of all the numerals you saw and their uses. (2) Basic Operations with Whole Numbers--e.g.; How high is the basketball basket? How high can you jump? How far can you broad jump? What is the difference between the height and the distance you can jump? What is the ratio between them? (3) Measurement (Time, Linear, Weight, Area, Temperature)--e.g.; (Time) Estimate the time it would take you to walk and then run the length of your block. Time yourself. Do this for several distances. Record your data. (4) Geometry--e.g.; Take a walk. Look for shapes that are symmetrical. How many axis of symmetry do they have? (5) Probability and Statistics--e.g.; How many stores are there on your block? What kind? (6) Problem Solving--All activities. (JC)
