Square Roots.
Peer reviewed Peer reviewed
Edge, John – Mathematics in School, 1979
Two algorithms are developed for finding the square roots of numbers. One is based on the rule that x square is the sum of the first x odd numbers; the other is algebraic. (MP)

Creating Algorithms for Multiplication
Cohen, Don – Mathematics Teaching, 1976
Upper elementary school students created their own algorithms for finding products of whole numbers. The algorithms were similar to familiar ones for finding products involving 9 and 11. (SD)

Some Variations on a Mathematical Card Trick.
Peer reviewed Peer reviewed
Markowitz, Lee M. – Mathematics Teacher, 1983
Variations on a card trick are noted, with a formula for generalizing them. Another trick which can be proved with algebraic principles is then presented. (MNS)

Lattice Multiplication and Division.
Peer reviewed Peer reviewed
Broadbent, Frank W. – Arithmetic Teacher, 1987
A modern adaptation of the historic lattice algorithm which can be used for multiplication and division is discussed. How it works is clearly illustrated. (MNS)

Children's Strategies for Solving Subtraction-Fact Combinations.
Peer reviewed Peer reviewed
Beattie, Ian D. – Arithmetic Teacher, 1979
Four procedures used by children for deriving answers to unknown subtraction facts are described. They are counting forward, counting backward, derivation, and bridging. (MP)

Theresa and Subtraction.
Hart, Maurice – Mathematics Teaching, 1979
One teacher's struggle with conveying a concrete realization of the subtraction algorithm to students leads to a discussion of elementary mathematics instruction in general. (MP)

Procedures and Algorithms in Primary Mathematics.
Peer reviewed Peer reviewed
Straker, Anita – Mathematics in School, 1986
The first aim in school might be to help children become more aware of the algorithmic processes they use; then, ensure that they can devise algorithms and define them. Many examples of how these aims can be met are given, including the use of calculators and computers. (MNS)

The Learning of Number Facts in the Primary School. Curriculum Paper.
Boxall, Ron; And Others – 1979
This paper is designed to provide teachers with more guidance on how to help students become proficient in the recall of basic number facts. Activities and practices are placed in a sequence designed to aid all instructors. The learning of number facts is divided into three stages: (1) the development of basic number facts; (2) establishing number…
