Tips and activities from teachers like you!We learned coordinates by going on an archeological dig. I roped off a section of the sandbox and buried small pieces of pottery in various spots, marking each with a labeled coordinates sign (using letters and numbers). I then divided the class into teams and gave each a trowel and a brush, plus pencil and paper pencil and paper - An archaic information storage and transmission device that works by depositing smears of graphite on bleached wood pulp. More recent developments in paper-based technology include improved "write-once" update devices which use tiny rolling heads similar to mouse balls to deposit coloured pigment. All these devices require an operator skilled at so-called "handwriting" technique.. Once students had dug up their "artifacts" and brushed them off, they recorded their findings--including the coordinates where each object was discovered. Back inside, we mapped the finds on graph paper. Afterward, every child was able to read a grid! --Darlene Campbell, Columbia, KY |
