#### Factorising Quadratics Worksheet - A how to guide with questions and answers

(0)
A visual and step by step worksheet (ideal for one lesson) teaching students how to factorise quadratics using the box method. Two resources included - one for Foundation and one for Higher. Higher worksheet covers quadratics where coefficient of x square = 1 and not = 1. Answers provided.

#### Completing the square using a visual method - A how to guide with questions and answers

(0)
Visual method and step-by-step help on how to complete the square. Includes 2 examples and 4 questions which help students to access the how and why of completing the square as well as serving as a good introduction to the topic. Questions cover the form for x^2 + bx and x^2 + bx + c. Answers provided.

#### Pseudocode algorithms worksheets x 2 - 1. Matching algorithms, 2. Fill in the blanks - Ideal lesson starters, plenaries or homework

2 Resources
Help students win at pseudocode with these low stakes and student friendly starters, plenary or homework activities. RESOURCE 1: The pseudocode fill in the blanks activity helps students become familiar with pseudocode by having to complete 3 pseudocode programs. The activity includes use of IF statements, FOR loops and WHILE loops. Ideal for a starter, plenary or homework. Answers included. DOC and PDF file formats provided. RESOURCE 2: The pseudocode matching activity helps students become familiar with pseudocode by asking them to match pseudocode programs to their purposes (or explaining them if higher ability). This activity includes use of IF statements, FOR loops, WHILE loops, STRING manipulation, FUNCTIONS and ARRAYS. Lower ability students can do the matching activity and higher ability can provide the purpose rather than match. Files for both included as well as answers. DOC and PDF file formats provided.

#### Pseudocode algorithms worksheet - Loops / iteration - Ideal lesson starter, plenary or homework

(0)
Help students become proficient with iteration / loops and pseudocode by asking them to identify infinite loops as well as providing loop counts for non-infinite loops.
