Reviews: "ArithMagic (Counting, Addition, Subtraction)" which uses graphics to illustrate/review basic arithmetic concepts; "The Sweet Shop" which uses graphics (and a character called Mr. Jellybean) to teach arithmetic concepts; and "Math Magic," a monster-filled arcade game that teaches addition and subtraction.…

This study: (1) documented the spontaneous derived facts strategies (DGSs) that second-grade children (N=23) used; (2) investigated how training in use of DFSs influenced the solution strategies children used to solve addition and subtraction problems; and (3) examined the role of DFSs in the transition to recall of number facts.

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)

Specific instruction in different contexts provide needed background for solving addition and subtraction problems. The categories of problems and relative difficulties are presented, followed by an explanation of a successful instructional sequence. (MNS)

This study involved 179 9-year-olds and 352 13-year-olds in New Zealand. Four addition and four subtraction tasks were set to ascertain students' ability to use the number line. Comparison of these data with results from the national assessment in the United States are given. (MNS)

Presents activities involving the addition of antinumbers (which uses novel numerical characters); a puzzle which combines practice in working with polynomials and solving simple equations with intriguing facts about turkets; and searching for the number of different right triangles in a given square grid (which helps develop spatial…

Fourth-grade students in Title I mathematics took 40-problem tests to determine types of persistent errors made in addition and subtraction. Tests, administered to 117 students (addition) and 104 students (subtraction), were analyzed for basic fact, random, or procedural errors. Findings are reported and discussed, and recommendations for…

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

This book explores how primary school children with dyslexia or dyspraxia and difficulty in math can learn math and provides practical support and detailed teaching suggestions. It considers cognitive features that underlie difficulty with mathematics generally or with specific aspects of mathematics. It outlines the ways in which children usually…

The purposes of this paper are to present research related to the development of new instructional games (named Survivor's Games), and measure the effectiveness of these games to help students (K-5) master basic fact operations (single-digit additions or factor and single- or double digit sums or products), stimulate the exploration of…

An experiment is described in which 11 naval enlisted men track and simultaneously perform an addition task with or without overt responses. (Editor)

Patterns in an array of numerals are analyzed; suggestions are given for guided discovery activities leading to a discussion of the properties of identity, closure, commutativity, inverses, and associativity. (DT)

Suggested activities involving number patterns, using the idea of a number machine." (MM)

The experiences described here use the idea of movement along the number line to reinforce the student's concept of addition and subtraction of both whole numbers and fractions. Four student worksheets and teacher guides are included. (MM)

The author describes a home-made manipulative aid which provides practice in addition. (MM)
