Teaching Number Sense

Teaching Number Sense Header

Teaching Number Sense is a key component to any maths program and when teaching numeracy, teachers should be aware that student achievement levels are directly linked to number sense.

The term Number Sense refers to a student’s “fluidity and flexibility with numbers,” (Gersten & Chard, 2001).  Teaching number sense involves strategies that develop student  understanding of what numbers mean, how they are connected,  are able to perform mental maths, understand symbolic representations, and can use numbers in real world situations.

Teaching Number Sense

Teachers need to plan to teach students number sense if their maths programs are to be effective. Students with good number sense can reason flexibly about numbers,  they can spot unreasonable answers, understand how numbers can be taken apart or partitioned, and put together in different wayssee connections, and figure things out mentally.

The National Council of Teachers in 1989 identified the following five components that characterise number sense:

  • Number meaning
  • Number relationships
  • Number magnitude
  • Operations involving numbers and referents for number
  • Referents for numbers and quantities

These skills are considered important because they help students to lay the foundation for mental arithmetic as well as more advanced mathematical skills. Researchers have linked good number sense with skills observed in students proficient in the following mathematical activities:

  • mental calculation (Hope & Sherrill, 1987; Trafton, 1992);
  • computational estimation (for example; Bobis, 1991; Case & Sowder, 1990);
  • judging the relative magnitude of numbers (Sowder, 1988);
  • recognising part-whole relationships and place value concepts (Fischer, 1990; Ross, 1989) and;
  • problem solving (Cobb et.al., 1991).

Dr. Jo Boaler describes what happens to low achieving students who don’t have good number sense:

The low achievers did not know less but they did not use numbers flexibly – probably because they had been set on the wrong path, from an early age, of trying to memorize methods and number facts instead of interacting with numbers flexibly.Jo Boaler

How do you teach number sense?

A large body of research has shown that number sense develops gradually, over time, as a result of exploration of numbers, visualising numbers in a variety of contexts, and relating to numbers in different ways.

Marilyn Burns suggests the following key, research-based teaching strategies to build numbers sense:

  • Model different methods for computing
  • Ask students regularly to calculate mentally
  • Have class discussions about strategies for computing
  • Make estimation an integral part of computing
  • Question students about how they reason numerically
  • Pose numerical problems that have more than one possible answer

 

 
Just as our understanding of phonemic awareness has revolutionized the teaching of beginning reading, the influence of number sense on early math development and more complex mathematical thinking carries implications for instruction.Gersten & Chard

Teaching Resources For Number Sense

One of the easiest ways to incorporate teaching number sense into your maths lessons is to include  “Today’s Number” or “Number of The Day ” activities in your program.

Frayer Think Board

The Frayer Board Think board Template is a graphic organiser, designed by Dorothy Frayer and colleagues at the University of Wisconsin in 2001. The Frayer Model helps activate students’ prior knowledge about a concept or word. Using the Frayer Think Board Template provides students with the opportunity to clarify a concept and communicate their level of understanding. The Frayer Board encourages students to create a definition, describe characteristics or properties of the word or concept, list examples and non-examples from their own prior knowledge of the concept or familiarity with the term.
