Students work on questions 1,8,9,10
Gave students 15 minutes to work on these questions and assigned the rest of the worksheet for homework.

Making measurements of length.
Measure to smallest scale division or even to 1/2 of smallest scale division. If you are using a ruler with divisions in millimeters, you should be able to make your measurement either 0.1 cm or 0.05 cm.
Always look straight down. If you look to the side your measurement will not be correct.

Rules for Rulers - don't abuse

Students worked in groups of 3.

All students should have finished making and swapping measurements. If they didn't finish the graph, they were asked to finish it for homework. I made a point of asking if they had that assignment in their planners.
