Description¶

Arithmetic fact retrieval is the ability to pull basic number combinations (3 + 4, 6 × 7) from long-term memory efficiently, accurately and flexibly, rather than working them out each time, so that they can be used inside larger calculations. It is usually assessed by having learners solve simple problems while their strategy is observed or self-reported (did they retrieve the answer or count it out?), and, for a fuller picture of accuracy, flexibility and efficiency, through interviews, observations and short untimed quizzes.

Facts are usually in place by the end of primary school, but the Learner Variability Navigator notes that fluent and flexible retrieval continues to support mathematics learning through high school. Learners with dyscalculia may have weaker representations of number, which can make facts harder to retrieve, and learners with dyslexia may also find retrieval harder because of its reliance on phonological processing. It builds on number sense and on long-term memory, and is used inside operations. Knowing when retrieval is the right strategy is part of mathematical flexibility. See also learning disabilities.

Implications¶

Context¶

Retrieval practice of facts sits alongside, not in place of, understanding of number relationships and strategies.
Math activities at home, such as counting games, support fluent retrieval.
Stereotype cues about who is good at mathematics can depress performance on fact tasks.

Target Learners¶

Primary-age children learning number facts.
Older learners whose calculation is slowed by counting out facts, including learners with dyscalculia or dyslexia.

Target Learning Objectives¶

Fact fluency: speed, accuracy and appropriate use of retrieval.
Multi-step calculation and later fraction problem solving.

Measures¶

Open-ended formats (Kling & Bay-William, 2014): Using a range of measures including student interviews, observations, writing prompts, and short, untimed quizzes around solving simple arithmetic problems can help capture students' accuracy, flexibility, and efficiency which are core components of Arithmetic Fact Retrieval.
Arithmetic Fact Retrieval Task (LeFevre, Sadesky, & Bisanz, 1996): Assesses Arithmetic Fact Retrieval by asking students to solve simple math Operations and observing or asking for self-report on strategy use.

Attention: more attentive students are more likely to use retrieval accurately.
Executive Function: cognitive flexibility goes with quicker retrieval of simple sums.
Long-Term Memory: difficulty with fact retrieval likely reflects difficulty recalling mathematical facts from long-term memory specifically.
Working Memory: learners with higher working memory lean on retrieval where it helps.
Number Sense: a firmer grasp of symbolic number magnitude goes with faster fact retrieval.
Operations and Place Value: fluent calculators retrieve facts for simple problems and use procedures for complex ones.
General Cognitive Ability: stronger reasoning goes with faster retrieval of simple addition facts.
Communication Skills: phonological processing, which LVN files under math communication, helps store and retrieve number facts.
Mathematical Flexibility: flexible learners can recognise when retrieval is the right strategy.
Proportional Reasoning: better fact retrieval goes with greater improvement in fraction problem solving over time.
Access: late language exposure among children with hearing loss can make verbally stored facts harder to recall.
Motivation: early mathematical skill and academic motivation appear to reinforce each other.
