A trick you can do by calculating the sum of a three by three block of dates on a calendar without using a calculator.
Learn how to use a grid reference system to describe locations and describe routes using landmarks and directional language. Unearth the key to reading maps with grid lines and join Eric in his search for a hidden buried treasure. Arr!
Using clothes to make different pairs, this episode introduces the concept of possibilities (possible outcomes) and combinations (different combinations and total outfit combinations).
Learn to recognise that fractions refer to equal parts of a whole in this episode which is about patterns in rhythms and musical notes. Discover the role of fractions in denoting whole, half, and quarter notes, and creating distinct sounds.
Learn how to compare angles and classify them as equal to, greater than or less than a right angle. If you place two mirrors at an angle, you will see an ever increasing number of objects as you move the mirrors closer together. If the two are parallel, you can see infinity.
Watch and be amazed as mathemagician Eric makes a tessellation using a geometric tile in the shape of his head.
This episode introduces paper engineering: the art of following a specific sequence of origami folding instructions using a standard sheet of paper, a few cuts and reverse folds to construct a 3D object.
Eric is tangled up with what seems to be a never-ending challenge. How will he make a set of linking rings from one strip of paper?
This episode explores an alternate way to communicate numbers using the anchor numbers five and 10 and the ancient counting system based on letters from the Roman alphabet.
The episode demonstrates how all numbers can be converted into palindromes using a reverse and add rule (algorithm).
This episode is all about capacity. Take two different shaped containers for example: a tall, skinny cylinder and a short wide one. Which one will hold more beads?
Behold, a centuries-old math trick that uses a lattice grid to multiply two-digit numbers. The mystery is straight and simple.
Learning to lace and tie shoes is a hurdle that everybody has to overcome in the course of growing up. Have you ever wondered how many ways you can tie a shoelace? Eric shows us a couple of the 43,000 ways.
Intercept a secret message. Eric cracks the code to decrypting the ancient cipher box used by Roman emperor Julius Caesar over 2000 years ago.
In this episode, we see how accurate estimates are arrived at by using information about many things in our everyday lives, in logical ways.
This episode demonstrates how following a specific sequence of arithmetic steps and the special properties of nine will always result in the same answer, in this case the number four.
This episode is about the concept of a measurement unit; non-standard measurement units; non-standard measure; and, indirect measure.
This episode uses a fixed set of computational steps that use simple arithmetic and basic algebraic conventions (eg doubling expressions to generate a known solution).
