 1. The row of Pascalâ€™s Triangle containing just two ones is normally referred to as row 1. The solitary one at the top of the triangle is row zero. Row two contains the numbers 1,2 and 1 in that order.What is the number in row 5 next to the one? 2. What is the sum of all the numbers in row 4? 3. What is the sum of all the numbers in rows 0 to 6? 4. The sum of the numbers in a particular row add up to $$x$$. What do the numbers in the row below this row add up to? 5. A calculator can be used to find any number in Pascalâ€™s Triangle given the row number and the position of the number from the left of the row [noting that the first number in a row is in position zero]. Click the HELP tab above for information about using a calculator for the following questions:Use a calculator to find the number in row 20, position 4. 6. Use a calculator to find the number in row 41, position 5. 7. The number in row 27, position 3 can be represented as $$\begin{pmatrix}27\\3\\ \end{pmatrix}$$Find $$\begin{pmatrix}27\\3\\ \end{pmatrix}$$ 8. Find $$\begin{pmatrix}53\\50\\ \end{pmatrix}$$ 9. The calculation $$\begin{pmatrix}5\\3\\ \end{pmatrix}$$ can be written as 5C3 (pronounced five choose three) and can be used to find the number ways of choosing three items from five.How many ways are there of choosing 2 players from a team of 11? 10. How many different ways can seven cakes be chosen from a tray containing ten cakes?

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 9 October 'Starter of the Day' page by Mr Jones, Wales:

"I think that having a starter of the day helps improve maths in general. My pupils say they love them!!!"

Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School:

"What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun."

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.

#### Playing Card Maths

Imagine you are on a desert island with nothing but a pack of playing cards. Do you have to stop learning mathematics? Of course not! Here are some great ideas for teachers, parents and tutors.

There are answers to this exercise but they are available in this space to teachers, tutors and parents who have logged in to their Transum subscription on this computer.

A Transum subscription unlocks the answers to the online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum Topic pages and the facility to add to the collection themselves.

Subscribers can manage class lists, lesson plans and assessment data in the Class Admin application and have access to reports of the Transum Trophies earned by class members.

## 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.
