Ratios and mean, median and mode - learning with the children

These two projects employ a wide range of children's faces in order to teach about various different qualities of proportion. Mean, median, mode, ratios, fractions and percent excersizes can all be constructed using the images of the children. Simply change the text in the excersize and a new challenge can quickly be constructed, either by a teacher or a student.

Designed to help students explore the relationships between fractions, ratios and percentages, a few slides have already been created featuring problems that can be solved, or adjusted as seen fit. In total, there are 24 different faces available, but whoever is designing a new excersize can easily simplify the excersize to fewer students. Or possibly replicate a few faces and insist there are identical twins in the sample. The final few slides provide an image of simply the faces, one with names and one without. These can be copied between new Explain Everything projects as can images in any of the other projects. This can be useful for creating new projects without needing to start from scratch all over again. The slide with names can also be used like a "guess who" game, where students secretly select one of the children's faces and then try to guess, based on a series of yes/no questions which face their opponent has selected,

This project involves a few different excersizes in determining mean, median and mode. The first is based on hair length, the second test scores and the last bouquets of flowers. The flower slide in particular can be changed so that the numbers of bouquets varies and new excersizes can be constructed.

Sorting and Patterns

The next couple of projects involve sorting objects and creating patterns.

A mish-mash of objects in the style of "I Spy" and search n' find books. Students can be asked to sort things based on a variety of qualities - colour, whether something is edible, whether it's a plant - so forth and so on. A good exploratory excersize, where the objects can be moved into categories determined either by the student or the instructor.

A game for pattern completion, the slides range from fairly easy to fairly complex. Items can vary by colour, type of candy and - in later slides - whether or not they are spotted. Extra slides are included so that it is easy for instructors to make additional excersizes. Below is just a short clip of when four year-old Hayden was building the rest of the patterns for the first excersize. This one was quite the favourite of his.
