Practice reading the protractor with students. h) Mount the completed protractor on stiff cardboard for outdoor handling. All slices should be the same size and width. g) Check for accuracy by comparing each “slice” of five degrees in the enlarged protractor. f) Extend degree lines to the outside arc and label them. Mark all degree points of five-degree increments. (Make the diameter to cover as much of the paper as possible.) e) Place a standard plastic protractor on the baseline and centred on the centre point. d) Construct a large semi-circle using a length of string pinned down at the centre point and with a pencil tied at the appropriate diameter length. c) Draw a line perpendicular to the centre point. Procedure a) Start by drawing a baseline the length of the paper. Larger protractors are possible, but can be unwieldy for children (see diagram A, Appendix A, page 125). pin or tack The enlarged protractor should be at least the size of an 8 x 14 inch piece of legal paper.Students learn to make their own protractors in the following activity: Materials Accuracy of angle measurement is important for accuracy of distance calculation. Making a Protractor When measuring angles outdoors, a large protractor will help to increase accuracy. Activity A, below, describes how students can make a large protractor. This may be constructed from an enlarged photocopy, or constructed by the students. A large protractor is also useful for making outdoor measurements. Familiarity with angles, angle measurements and the use of a protractor is essential to this activity. To measure distances with triangulation requires a protractor or a compass to measure angles. The principles of geometry and angle measurement may be too difficult for younger students. Measuring distances by triangulation using a protractor and a baseline The following activity is suited to advanced grade 6 or grade 7 students. Patterns, Plants and Playgrounds Unit 2 Theme 1 10. Clues Found: - Patterns, Plants and Playgrounds Distance to next Station 65 meters 20 meters 56 meters 27 meters etc. Station # 1 2 3 4 5 6 7 Figure: Example Orienteering Course Sheet (See worksheet, Appendix A, page 124.) Station Letter - Direction to next Station 45˚ NE 180˚ S 275˚ NW etc. Optional extension Provide a base map of the activity site for students to record their progress and the location of each station site as they go. ![]() Mix up letters found at each station that the students must unscramble to complete the activity. For an added challenge, provide clues, or math challenge questions that must be decoded in order for the students to figure out the direction of the next station. Record all measurements and check for accuracy. Once all the signs are posted, proceed around the course, taking compass readings and stepping off measurements between each station. Try to post signs near to eye level and do not hide them under things. Keep the course simple, but add challenges by posting station signs on the backs of tree trunks, goal posts and backstops. Be mindful of student damage to foliage and keep an eye out for possible dangers such as insect nests, irritating plants (nettles, poison ivy, etc.) and other obstacles. Stations should be at least 10 meters away from one another and fairly easily accessible. base map of activity site, or directions sheet Course Set-up Locate and post at least 10 station signs around the activity site that will be clearly visible to students approaching from several directions.With practice, students can even set up their own courses and challenge their classmates. There are many possible variations of orienteering that can be done on a school ground. The following activity brings the skills of compass direction finding and distance measuring together. Orienteering: intermediate skills Orienteering can be a very physically challenging activity that requires a variety of skills.
