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 25 June 'Starter of the Day' page by Inger.kisby@herts and essex.herts.sch.uk, : "We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much Comment recorded on the i asp?ID_Top 'Starter of the Day' page by Ros, Belize: "A really awesome website! Teachers and students are learning in such a fun way! Keep it up..." |
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. |

Go MathsLearning 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 page is an alphabetical list of free activities designed for students in Secondary/High school. Maths MapAre you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic. | ||

"The questions in the six levels of this of exercises range from the laughingly easy to the head-scratchingly hard. The last question of level 6 was adapted from one that appeared on a Senior Mathematical Challenge (SMC) paper.
The SMC is a 90-minute, multiple-choice competition from the UK Mathematics Trust aimed at students (Year 13 and below) across the UK. It encourages mathematical reasoning, precision of thought, and fluency in using basic mathematical techniques to solve interesting problems. The problems on the Senior Mathematical Challenge are designed to make students think. Most are accessible, yet still challenge those with more experience."

"The directions say to measure the side lengths to the nearest centimeter, then those side lengths to calculate area and perimeter. If you do that for the middle parallelogram, you get a base of 5 cm and height of 2 cm. The area should be listed as 10 square cm. It is only if you measure the side lengths to the nearest HALF cm that you come closer to the "correct" answer of 12 square cm, which should actually be 13 square cm when 12.5 (2.5 x 5) is rounded to the nearest whole number.
[Transum: Thanks for pointing out this issue Mindy. It is interesting that because of the rounding instruction a different value for the area is obtained depending on whether you use the horizontal line as the 'base' or choose to consider the sloped line as the 'base'. The software now marks either version as correct. Thanks again for taking the time to point this out. A great thing to discuss with students.]"
