### Estimation: How big is this Gulliver? - mathematics activities

Despite there not being formal measurements in the photograph, it is possible to estimate the height of the giant from the information in the photograph. The only full body part of the giant that can be seen is the left foot. The image shows all of the two, presumably 'normal-sized', men who are approximately the same height, ...

### Home-run records

This realistic mathematical investigation uses stem and leaf plots to compare the performances of two baseballers. It examines the effects of outliers on the mean. The task includes a student worksheet with data, teacher notes, assessment advice and ideas for extension. ICT could be used.

### Graph investigator: concentration

Do students with better concentration have faster reaction times? Select the appropriate data sets and choose a useful graph type to investigate this question. See the data presented in the chosen graph type and draw a conclusion about this question. Explore different graph types such as scatter plots, line graphs and histograms. ...

### Stem-and-leaf graphs: reaction time

Do right-handed students have faster reaction times than left-handed students? Display the given data, including your own time, in a back-to-back stem-and-leaf graph to investigate the answer to this question. Identify the median for left- and right-handed students and use the two means to help you draw a conclusion about ...

### Data handler: bus timetable

Help plan your school sports day by organising buses for all the students. Plot raw data on a dot plot and then group that data according to three criteria or 'rules' to decide the minimum number of buses required and departure times to suit all students.
