    en.wikipedia.org/wiki/Word_problem_(mathematics...

    For instance, if the one solving the math word problem has a limited understanding of the language (English, Spanish, etc.) they are more likely to not understand what the problem is even asking. In Example 1 (above), if one does not comprehend the definition of the word "spent," they will misunderstand the entire purpose of the word problem.

    The word problem for an algebra is then to determine, given two expressions (words) involving the generators and operations, whether they represent the same element of the algebra modulo the identities. The word problems for groups and semigroups can be phrased as word problems for algebras. [1]

    en.wikipedia.org/wiki/Metanarrative

    Metanarrative has a specific definition in narratology and communications theory. According to John Stephens and Robyn McCallum, a metanarrative "is a global or totalizing cultural narrative schema which orders and explains knowledge and experience " [ 19 ] – a story about a story, encompassing and explaining other "little stories" within ...

    More recently, a simpler version has been used to study how students react to word problems: A captain owns 26 sheep and 10 goats. How old is the captain? [4] Many children in elementary school, from different parts of the world, attempt to "solve" this nonsensical problem by giving the answer 36, obtained by adding the numbers 26 and 10.

    The optic equation of the crossed ladders problem can be applied to folding rectangular paper into three equal parts: ⁠ 1 / 1/2 ⁠ + ⁠ 1 / 1 ⁠ = ⁠ 1 / h ⁠ ∴ 2 + 1 = ⁠ 1 / h ⁠ ∴ h = ⁠ 1 / 2 + 1 ⁠ = ⁠ 1 / 3 ⁠ One side (left in the illustration) is partially folded in half and pinched to leave a mark.

    It is the smallest example of a nonplanar Laman graph. [23] Despite being a minimally rigid graph, it has non-rigid embeddings with special placements for its vertices. [ 9 ] [ 24 ] For general-position embeddings, a polynomial equation describing all possible placements with the same edge lengths has degree 16, meaning that in general there ...

    en.wikipedia.org/wiki/Three-part_lesson

    The role of the teacher is to "get students mentally prepared to work on the problem". [1] Marian Small, a proponent of a constructivist approach to mathematical instruction, provides an example of an inquiry-based question from which a three-part lesson could be created: "one bus has 47 students in it; another has 38. How many students are on ...
