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.

Cake or Book? - Fractions

There are truly endless ways to represent a fraction and knowing that, isn't it far more fun to have a cheerful way of thinking of fractions? Below are several projects designed to help teach students about equivalent fractions as well as a few ideas for how problems can be constructed using these colourful manipulatives.

The first is a rather simple piece that provides a few pie chart manipulatives for helping students measure equivalent fractions. The pies are divided into fourths, fifths, eigths and tenths.

Next is the bookcase. Using the transparent books, students can compare the lengths of different sizes of various fractions as they fill the shelves. A single dictionary fills 1/2 the shelf, but what about the entire case? Then it only fills 1/6. How many copies of "Treasure Island" would be needed to fill the case? The books can also be compared on a number line ranging from 0 through 1. On the final slide, students can practice adding fractions by combining the first two shelves into a single string of books at the bottom.

Finally, everything is better with cakes, and of course that includes fractions! Students stack layers of cake to create giant, teetering monstrosities of birthday merriment. A few "finish the cake" problems are included and the vertical alignment gives another concrete way of thinking about how fractions can be presented in day to day life.
