“Standard Form - Notes, Examples and Exercises” introduces the use of standard form (or scientific notation) for very large or very small numbers. A section on using standard form on a calculator is included. Display screens on calculators have improved over the years but entering numbers in standard form and interpretation of what is displayed on a screen can still cause many problems. Four exercises containing a total of over 50 questions with answers are included in this unit of work which is suitable for self-study and ranges from beginner to GCSE standard. Pdf and ppt versions of this resource are included in the download which contains 12 A4 pages/slides.

Worked examples and 63 questions on simultaneous equations in four exercises. Answers included. “Solving Simultaneous Equations Using The Elimination Method” introduces the technique with worked examples. Problems solved by the formation of simultaneous equations from given information are included. Pdf and ppt versions of this resource are included in the download which contains 15 pages/slides. This unit of work is suitable for self-study and ranges from beginner to GCSE level. “Solving Simultaneous Equations Using The Elimination Method” can be downloaded as part of my Algebra Bundle resource package.

124 questions for revision practice on methods of differentiation. The questions (with separate answers) are contained in seven exercises. Exercises A, B and C of "Calculus - Revision Exercises on Methods of Differentiation" cover basic methods including the product rule, quotient rule and use of a substitution (chain rule). Later exercises are more advanced and differentiation may require a combination of methods. Exercise D involves logarithmic functions and Exercise E is on exponential functions. Exercise F (trigonometric functions) and Exercise G (implicit functions) complete this package. Pdf and ppt versions of this resource are included in the download which contains 15 pages/slides.
