The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz's 1929 text Algebra for Today, where he states: [2]
[1] [2] When n = 2, it is easy to see why this is incorrect: (x + y) 2 can be correctly computed as x 2 + 2xy + y 2 using distributivity (commonly known by students in the United States as the FOIL method). For larger positive integer values of n, the correct result is given by the binomial theorem.
This method was frowned upon by my high school math teacher by the fact that it can cause confusion and errors when answer expression with positive/negative numbers. ie. (x + 3)(x - 7) = the answer could be incorrect by the confusion of the minus sign. I think there should be some articles that explains the negative aspect of this rule.
The reverse jigsaw method resembles the original jigsaw method in some way but has its own objectives to be fulfilled. While the jigsaw method focuses on the student's comprehension of the instructor's material, the reverse jigsaw method focuses on the participant's interpretations, perceptions, and judgements through active discussion.
Like the ID3 algorithm, FOIL hill climbs using a metric based on information theory to construct a rule that covers the data. Unlike ID3, however, FOIL uses a separate-and-conquer method rather than divide-and-conquer, focusing on creating one rule at a time and collecting uncovered examples for the next iteration of the algorithm.

Backward design is a method of designing an educational curriculum by setting goals before choosing instructional methods and forms of assessment. Backward design of curriculum typically involves three stages: [1] [2] [3] Identify the results desired (big ideas and skills) What the students should know, understand, and be able to do
The book begins with a historical overview of the long struggles with the parallel postulate in Euclidean geometry, [3] and of the foundational crisis of the late 19th and early 20th centuries, [6] Then, after reviewing background material in real analysis and computability theory, [1] the book concentrates on the reverse mathematics of theorems in real analysis, [3] including the Bolzano ...
The most primitive method of representing a natural number is to use one's fingers, as in finger counting. Putting down a tally mark for each object is another primitive method. Later, a set of objects could be tested for equality, excess or shortage—by striking out a mark and removing an object from the set.
