### Thinking Strategies for the Basic Facts

EDN 322

• Repetition is important

• Sequence the content in a series of small steps

• Learner fatigue decreases the effectiveness of drill

• Responses must be elicited from the learner so that correct responses can be rewarded and incorrect ones can be modified

• Commutativity

• Adding 0, 1

• Adding Doubles or Near Doubles

• Counting on

• Adding to 10 and beyond

• Using 0 and 1

• Doubles

• Counting Back

• Counting On

• Commutativity

• Skip Counting

• Splitting the Product into Known Parts

• Using 0 and 1

• Pattterns

• Think Multiplication

• Repeated Subtraction

• Computation begins at the left, rather than at the right as for the other operations.

• Involves not only basic division facts, but also subtraction and multiplication.

• There are a number of steps, but their pattern moves from one spot to another.

• Trial quotients must be used and may not be successful at the first or second attempt.

• Mental computation

• Estimation

• Written computation

• Calculators

Children should select appropriate computational methods from among “mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tool” (NCTM, 2000, p. 148)
