Activity: to investigate and extend number patterns [lo 2.1.1]

1. When we work with number patterns we either add or subtract to find the next number in the row. See if you can discover the pattern and then fill in the missing numbers:

1.1 50 850 ; ____________ ; __________ ; 50 700 ; 50 650 ; ______________

1.2 20 200 ; 20 400 ; ____________ ; ___________ ; __________ ; __________

1.3 ___________ ; ___________ ; 61 726 ; 60 726 ; ___________ ; __________

1.4 49 625 ; 59 625 ; ___________ ; ___________ ; __________ ; __________

Assessment

Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.

Assessment Standard 2.1: We know this when the learner investigates and extends numeric and geometric patterns looking for a relationship or rules, including patterns

2.1.1 represented in physical or diagrammatic form.
