Australian Curriculum Version 9 Says:

Recall and demonstrate proficiency with addition facts to 20; extend and apply facts to develop related subtraction facts.

What this means

Recall (remember) the addition facts to 20.

  • Recall; first level of recall is remembering a fact.
  • Later, Automatic recall implies the fact is so well known that little mental processing is required.
  • Note: Using a mental strategy to reconstruct a fact would not constitute recall, but it is important that a student can reconstruct a forgotten fact.

Tip

  • Research suggests that students will struggle with complete recall of facts to 20 at Year 2. Typically researchers use a 3-second time when judging fluency.
