To solve challenging problems, pupils will  move on to learn

  • the Chicken-Rabbit Approach to solve challenging distributive property problems; 
  •  a grouping approach with LCM property for challenging counting problems;
  • the use of the Greatest Common Unit procedure (based on Euclidean Algorithm) for advanced ratio approach;
  • the bar modelling approach to time-distance corresponding relations for complex speed problems involving different journeys. 

Pupils will learn through challenging problems in the following units :

Unit 8:  Challenging Distributive  Problems 

Unit 9:   Challenging Problems.

Unit 10:  Speed Problems
