XNumbers and the National Curriculum.

XNumbers have been developed specifically with the National Curriculum in mind and have been extensively tested in a classroom situation..

The main focus is on the practice of arithmeticskills using pencil and paper, and as such the majority of puzzles specify that calculators should not be used.

The following table sets out the areas of the National Curriculum which are covered by each pack. Please note that XNumbers within each pack appear in that pack only and are not duplicated in the other pack.

Each pack contains over 90 original and fully photocopiable puzzles.

NumberScramble


NumberScramble is a new twist on the original XNumber idea . Solve the clues, then enter the solutions into the grid. However, some of the solutions need to be scrambled before they are entered into the grid, providing more of a challenge to hardened puzzle solvers. Not only are arithmetic skills tested, powers of logic and deduction are stretched to the extreme, especially when the NumberScramble is tied in with a Star XNumber or a Missing Operator XNumber.

 

NumberScramble (51Kb) is available now to buy and costs only £1.50 or $2.50 for the collection of 10 puzzles.




NumberScramble contains 10 puzzles, with difficulty ranging from the more straight forward basic puzzles through to the more taxing MissingOperator, Multiples and Star XNumbers. Each puzzle has been saved as an EXCEL spreadsheet and has been formatted to print out onto an A4 sheet of paper without any need for adjustment.
