#### Product Information

The full set of 10 PowerPoint Presentations on Types of Number and Sequences (183 slides, excluding Title Pages) covers the following topics:

• 01 Multiples, Factors & Prime Numbers (22 slides)Explains multiples, lowest common multiples (LCMs), factors, highest common factors (HCFs) and prime numbers.
• 02 Prime Factorisation (15 slides): Explains how to express a number as a product of its prime factors and how to find the LCM and HCF of several numbers once they have been expressed as products of their primes.
• 03 Squares, Cubes & Roots (21 slides): Explains square numbers, square roots and their link to the 2D shape, and explains cube numbers, cube roots and their link to the 3D shape.
• 04 Indices & Laws of Indices (25 slides)Explains positive and negative indices and the laws of indices.
• 05 Fractional Indices (8 slides)Explains fractional indices.
• 06 Surds (23 slides): Explains rational and irrational numbers, surds and surd laws, and how to rationalise denominators of fractions involving surds.
• 07 General Sequences (21 slides): Explains how sequences can be generated using written rules, number / function machines, practical situations and from expressions for the nth term.
• 08 Linear Sequences (16 slides): Explains how to find the next, previous or missing terms of a linear sequence, and how to find the expression for the nth term of a linear arithmetic sequence.
• 09 Quadratic Sequences (20 slides): Explains other types of sequences and how to find next or previous term and the expression for the nth term of a quadratic sequence.
• 10 Geometric Sequences (12 slides): Explains how to find the next or previous term of a geometric sequence, and how to find the expression for the nth term of a geometric sequence. INCLUDED in this download
