The *Zeta Club* is an maths enrichment club for Tiffin students, with a particular focus on the Olympiads and Maths Challenges. Details are below.

**Where:** Room 56

**Who with:** Ms Bickerstaff

**When:** Wed at 1.05pm

**Where:** Room 57

**Who with:** Dr Frost

**When:** Wed/Thur at 1.05pm (pick either day)

You can find my UKMT database here: www.drfrostmaths.com/ukmtdb, which contains all Maths Challenge, Olympiad, Kangaroo, Team Maths Challenge and some mentoring problems, all categorised by topic and subtopic, and with notes. You will need a username and password to access these - please ask me if you haven't already been supplied these.

If you are not at Tiffin you are welcome to use my older resources below.

All are harder questions from past JMCs, i.e. Q16-25, the point at which points are lost for incorrect answers. The topics for these questions are somewhat more evenly distributed than in the geometry-heavy IMC: within the 2004-2012 papers (Q16-25 on each paper), 14 were geometry, 22 number (ratios, time, numerical calculations, etc.), 5 number grids (filling numbers into structures according to some constraint), 23 on Number Theory (problems relating to integers: remainders, factors, digits, etc.), 20 on 'spatial reasoning', and 6 on non-applied algebra. These questions below are categorised according to these by topic to help you hone in on particular skills. Please contact me for answers.

- Algebra
- Geometry
- Number (ratios, time, numerical calculations, etc.)
- Number Grids (filling numbers in some grid/structure)
- Number Theory (problems relating to integers: remainders, factors, digits, etc.)
- Spatial Reasoning

Again, questions are categorised by topic, and 'fact sheets' provide key theory and tips for each of these topics. Section B advice I've written can be found here.

Sample student solutions can be found here.

# JMO Geometry Questions

## 2 files16/05/2016

Junior Maths Olympiad Section B questions on the topic of Geometry. Numerical solutions included. Note that the 'Puzz Points' were for when these were printed as laminated cards which I kept in a pack for use in lessons. 10 points corresponds to the first question, 15 points for the last.

All are harder questions from past JMCs, i.e. Q16-25, the point at which points are lost for incorrect answers. I've categorised these by topic to hone in on particular skills. The ratio of (harder) question types for 2004-2012 is somewhat interesting: 38 were geometry, 16 were some kind of 'spatial reasoning' (paths through networks, rotating objects, etc.), 16 were general number problems (e.g. ratio, time, density, etc.), 14 'number theory' problems (involving integers, primes, digits, etc.) and just 6 non-applied algebra. As with the Olympiad, clearly the key to a high score is to master the geometry problems, many of which follow a similar approach. Please contact me for answers.

- Algebra
- Geometry
- Number (ratios, time, numerical calculations, etc.)
- Number Theory (problems relating to integers: remainders, factors, digits, etc.)
- Sequences
- Spatial Reasoning

Again, questions are categorised by topic, and 'fact sheets' provide key theory and tips for each of these topics.

The breakdown of questions across a 8 year period: 59 Geometry questions, 28 Number Theory, 25 (non-applied) Algebra, 13 Spatial Reasoning/Logic, 6 Number Grids, 5 Speed/Distance/Time questions, 4 Sequences and just 1 Probability. Obvious conclusion: concentrate preparation on Geometry!

Because of this, I've prepared an extra worksheet involving finding difficult areas and lengths: Geometry Challenge Worksheet.
