Procedures for using an abacus to teach addition to learning disabled children are described. Considerations in choosing, constructing, and doing basic problems with an abacus are discussed. (CL)

A strategy is presented for teaching arithmetic to students with mental retardation, based on subitizing, skill of recognizing number of objects in a set without actually counting, and pattern recognition. The strategy helps children understand concept of addition by representing number configurations on 5-frames and 10-frames, and reduces need…

Very specific suggestions for teaching subtraction facts using addition are given. Several activities are suggested. (MK)

A teacher describes an activity designed to help children understand the number concepts of the basic addition facts with sums of 11 or greater. (CL)

A math strategy using an "add-card" which illustrates simple addition facts was originally developed for learning disabled students but was also successfully used with mildly retarded students. (CL)

How the manipulative aid called the "10 frame" can be used to teach the number combinations for 10, the addition facts that bridge 10, and the place value nature of our number system is described. (MNS)

Problems are discussed in which addition facts are presented using words instead of numbers. The letters are then replaced by numbers that will make the addition problems correct. (MP)

Presents two activities on addition, one for classifying and one for symmetry. (ASK)

An activity that offers computational practice, pattern recognition, and the formulation of generalizations is described. (JT)

Magic squares are used to generate number games similar to tic-tac-toe. Skills that are reinforced include addition of negative numbers and addition and multiplication of fractions. (MP)

Possible stages in young children's use of the number line as an aid are described. The practice of using number lines in test items is discussed and criticized. Finally, the wider role of the number line diagrams in mathematics teaching is outlined. (MNS)

A card game is described which gives students practice with adding integers and which also develops the concept of "opposite." (DT)

Novel practice exercises for addition and subtraction using a special number puzzle called a number chain are suggested. (MK)

Young children benefit from activities that involve various partitions of numbers, especially the number 10. Presented are two activities that require students partition and recombine numbers to solve problems in a gamelike situations. Examples and worksheets are provided. (MDH)

Discovering 3 by 3 magic squares, using numbers 1 through 9, is presented as a learning activity on three different levels. (MP)
