This is level 1: differentiate basic polynomials. You can earn a trophy if you get at least 9 questions correct and you do this activity online.

 $$y=x^{4}$$ $$\frac{dy}{dx}=$$ $$y=x^{3}$$ $$\frac{dy}{dx}=$$ $$y=x^{2}$$ $$\frac{dy}{dx}=$$ $$y=x$$ $$\frac{dy}{dx}=$$ $$y=x^{3}+x^{2}$$ $$\frac{dy}{dx}=$$ $$y=x^{4}-x^{3}$$ $$\frac{dy}{dx}=$$ $$y=x+9$$ $$\frac{dy}{dx}=$$ $$y=6x^{2}$$ $$\frac{dy}{dx}=$$ $$y=5x$$ $$\frac{dy}{dx}=$$ $$y=8x^{2}+2x+4$$ $$\frac{dy}{dx}=$$ $$y=3x^{3}-8x^{2}+7$$ $$\frac{dy}{dx}=$$ $$y=4x^{2}-6x-3$$ $$\frac{dy}{dx}=$$

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 3 October 'Starter of the Day' page by Fiona Bray, Cams Hill School:

"This is an excellent website. We all often use the starters as the pupils come in the door and get settled as we take the register."

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."

#### 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 page is an alphabetical list of free activities designed for students in Secondary/High school.

## Description of Levels

Close

Level 1 - Differentiate basic polynomials

Level 2 - Differentiate more polynomials

Level 3 - Find the gradient at the given point

Level 4 - Mixed differentiation questions

Exam Style questions are in the style of GCSE or IB/A-level exam paper questions and worked solutions are available for Transum subscribers.

Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.

## Example

The video above is from MathMateVideos.

## Terminology and symbols

Please note that if $$y = f(x) = x^2$$ then the first differential can be shown as:

$$\frac{dy}{dx} = 2x$$

or...

$$y' = 2x$$

or...

$$f'(x) = 2x$$
