Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 11 January 'Starter of the Day' page by S Johnson, The King John School:

"We recently had an afternoon on accelerated learning.This linked really well and prompted a discussion about learning styles and short term memory."

Comment recorded on the 21 October 'Starter of the Day' page by Mr Trainor And His P7 Class(All Girls), Mercy Primary School, Belfast:

"My Primary 7 class in Mercy Primary school, Belfast, look forward to your mental maths starters every morning. The variety of material is interesting and exciting and always engages the teacher and pupils. Keep them coming please."

Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.

Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

#### Three Ways

Can you get to the target number by multiplying together four different one digit numbers? Can you do it in three different ways? There are nine levels to this online challenge and a virtual Transum Trophy available for each level.

## Numeracy

"Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

## Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths main page links to more activities designed for students in upper Secondary/High school.

"Although Inertia Racetrack is a two-player game here is a suggestion for how to enjoy this activity as a one-player challenge. Use only the blue car (set the other carâ€™s vector components to zeros or let it crash) and try to drive around the course using the minimum number of moves. Claim a trophy to record your achievement then try to improve on your personal best.

The best I have seen so far are:
Track 1: 13 moves
Track 2: 19 moves
Track 3: 30 moves
Track 4: 25 moves
Track 5: 33 moves
Track 6: 33 moves
Track 7: 38 moves
Track 8: 37 moves
Track 9: 40 moves
Track 10: 50 moves

If you manage to complete a track in a smaller number of moves please let me know by copying and pasting you list of ordered pairs into a comment on this page (link below)."

## Instructions

The objective of the game is to be the first player to get around the racetrack and reach the red FINISH line.

Each player adjusts the numbers on their race vector by clicking on one or more of the red buttons at the sides of their vectors. This only allow a maximum increment of one each time (this provides the notion of inertia).

When both players are happy with their settings the 'Run Vectors' button can be clicked.

Continue this process until at least one of the plays reaches the FINISH line.

This racetrack uses some futuristic technology that allows two racecars to occupy the same space at the same time - Amazing!

If the race is a draw try racing again on one of the other racetracks (levels). If one player is a clear winner a virtual trophy can be claimed by that player.

The titles Player 1 and Player 2 are editable so your names can be typed in.

The image above shows a typical race that the blue car wins. The orange car crashed due to over-enthusiastic inertia!
