The Logical Number Sequences has been rated 5 stars

RESOURCE OVERVIEW:

In this activity pupils explain the rule for a number sequence and predict which numbers come next. In doing so, they extend their knowledge of simple rule based algorithms. They also use logical reasoning as they work out and explain their algorithms.

PUPIL OBJECTIVES:

I can use logical reasoning to explain how some simple algorithms work.

TEACHING ASSESSMENT OPPORTUNITIES:

Informal teacher assessment of pupils’ progress during main task, class discussion and plenary (focussing on asking pupils to explain the rule for a sequence and how they worked out the rule).
Assessment of sequence sheets if wished.
