A bit of a compromise but appropriate for Year 4 in practical terms.Bruce Ferringtonhttps://www.blogger.com/profile/07947474361978469990noreply@blogger.comtag:blogger.com,1999:blog-8256492698354362046.post-82554996608652704222012-09-05T22:20:44.052+10:002012-09-05T22:20:44.052+10:00I can see why the "Area and Perimeter Robot&q...I can see why the "Area and Perimeter Robot" activity was popular. Adding some art to maths would be more attractive to Year 4. I was able to make out their calculations on the pictures.<br /><br />The person who asked if it was possible to use triangles was interesting, particularly as he knew how to calculate the area of the triangle. I wonder if he discovered the disadvantage when trying to accurately calculate the perimeter of the robot? The sine equation would be a little advanced. :)<br /><br />@RossMannellrmannellhttps://www.blogger.com/profile/10325881715643049499noreply@blogger.com
