#### The concept of a half-way point is usually only thought of as an observation skill. We show students how to take that concept and apply it to data sets. We start by showing students where the middle value is found in a series of odd data sets. We advance to asking students where the half-way mark lies with a range of values. The goal of this section is leading students towards understanding the concept and calculation of mean and median of data. Students should write out the range to help them determine the answer.

These worksheets explain how to create number lines to determine which number lies halfway between two given numbers. Sample problems and practice problems are provided.
