## Venn Factors and Venn Multiples

A Venn Diagram is a powerful visual way to show the factors of a number, and the common factors of two numbers. Nice implementation.

## Are You A Psychic?

This resource is based on real experiments in the 1930s by Karl Zener who designed the cards used (now known as Zener Cards). The purpose is to test for clairvoyance. There are 5 different types of card and 5 of each design giving a deck of 25.

Students are shown the back of a card and are asked to choose what they think the card is. The resource keeps a tally and presents a frequency at the end. The frequency is only given at the end to emulate the normal use of tally charts.

Note that the card sequence is pre-determined, so this is best done as a one-off experiment.

## Archimedes' Bath

A fantastic implementation of the 'bath graph', ie the graph of water height vs time if a bath tap is turned on/off, and/or the plug is pulled out, and/or a person gets into/out of the bath. And a yellow duckie is included for free. Three thumbs up!

## Comparing Fractions, Decimals and Percents

A fantastic interactive activity! Students get lots of practice at finding equivalent fractions, decimals and percents. Three thumbs up!

The website has a fact sheet, a worksheet, a quiz and (best of all) a game for teaching this activity.
