Key ideas and conditions

Grouping

Objects can be grouped by a stated feature, such as shape or number. Say the rule so someone else can check it.

Patterns

A repeating pattern uses a repeat unit. A growing number pattern follows a stated change; a few terms can fit more than one possible rule.

Counting

Count each object once and use the last count word for the total. Drawing or moving counters can make reasoning visible.

Explanation

A learner can explain using words, pointing or a drawing. Accept an alternative rule when it fits the supplied examples and is clearly stated.

Explain without looking

  1. Make a different repeating pattern and describe its repeat unit.
  2. Why tell someone your sorting rule?
