It is the fourth lesson in a seven-lesson unit of work focused on ratio and rates. This is a "double lesson" of 69 minutes duration. There are 30 students in the class. This is one of four lessons that were chosen to represent the Australia data set. No individual lesson can capture all typical features of teaching in a country. However, the four public release lessons as a collection illustrate many typical features. The teachers filmed in this set of lessons volunteered to have their lessons included in the TIMSS 1999 Video Study Public Release collection. Their significant contribution to the field of education should be acknowledged with appropriate respect. This collection of lessons was videotaped for the specific purpose of education research. Therefore, the videotaping technique used was designed to minimize classroom disruption, and editing of the lessons was minimal.This lesson data, including the video footage, should be used for teacher professional development and education research purposes only. |

| Talkbank | - | - | 24 | 16 | SN | twenty nine? |
| Talkbank | - | - | 24 | 17 | T | twenty nine? |
| Talkbank | - | - | 24 | 18 | SN | about thirty. |
| Talkbank | - | - | 24 | 19 | T | so where are you getting these figures from? |
| Talkbank | - | - | 24 | 20 | SS | from the mean. |
| Talkbank | - | - | 24 | 21 | SN | the mean! |
| Talkbank | - | - | 24 | 22 | T | the mean? |
| Talkbank | - | - | 24 | 23 | T | okay. |
| Talkbank | - | - | 24 | 24 | T | let's just have a look at those three numbers again: a mean of thirty point five seven, a median of twenty eight point five, and a mode of twenty five. |
| Talkbank | - | - | 24 | 25 | T | so you are electing, in this case, to use the mean. |
| Talkbank | - | - | 24 | 26 | SN | yeah. |
| Talkbank | - | - | 24 | 27 | SN | yeah. |
| Talkbank | - | - | 24 | 28 | T | why? |
| Talkbank | - | - | 24 | 29 | T | why did you select the mean rather than the, uh, the mode for example? |
| Talkbank | - | - | 24 | 30 | T | yep? |
| Talkbank | - | - | 24 | 31 | SN | be cause that's on an average of, um, all of the |
