Important prerequisites for automatic recallīefore attempting to develop automatic recall in children, teachers should ensure that the children have certain prerequisite skills and knowledge. For instance, rather than memorizing the answer to 11 + 12, children should be taught the algorithm for 2-digit addition without regrouping (i.e., align the numbers vertically in columns, add the ones column, then add the tens column). It is important for teachers to know which equations are facts, because practice activities on these particular equations are essential for developing automatic recall for other (non-fact) equations, computational algorithms should be taught. However, 19 – 3 = 16 is not a subtraction fact, because 16 + 3 = 19 is not an addition fact.

For example, 10 – 7 = 3, 16 – 8 = 8, and 5 – 0 = 5 are all subtraction facts, because they are all inverses of addition facts (7 + 3, 8 + 8, 5 + 0). Subtraction facts are the inverses of the addition facts. Thus, 2 + 7, 9 + 6, and 8 + 3 are all addition facts, whereas 11 + 12 is not a fact because the addends are not single digits and the sum is greater than 18. What are the addition and subtraction facts?Īddition facts involve single-digit addends with sums to 18 (9 + 9). However, some youngsters with learning disabilities may have considerable difficulty with automatic recall despite basic fact instruction that is adequate for developing memorization of facts in most children. Adequate attention to promoting memorization of facts in the general education math curriculum may prevent or ameliorate problems with automatic recall in many students. One factor behind these difficulties may be that contemporary methods of math instruction, strongly influenced by the standards of the National Council of Teachers of Mathematics (NCTM), have tended to de-emphasize memorization of basic facts in favor of a greater emphasis on problem-solving and concept development. Poor automatic recall of facts is very common among struggling students. Here the focus will be on automatic recall of addition and subtraction facts, which develops in normally-achieving youngsters by about the end of second grade. Lack of automatic recall is a problem as children advance into the middle and later elementary grades, because the need to rely on laborious counting procedures creates a drain on mental resources needed for learning more advanced mathematics. When children have automatic recall of facts, they can quickly retrieve answers from memory without having to rely on counting procedures, such as counting on fingers. Basic math facts are the answers to simple equations in addition (e.g., 3 + 2), subtraction (e.g., 9 – 5), multiplication (e.g., 6 x 4), and division (e.g., 15 ÷ 3). Automatic recall of basic math facts, sometimes termed math fluency, is generally considered to be a key foundation for higher-level math skills.
