The concept of addition is helpful. For instance, adding up the cost of all school supplies.
Math can be used for things like calculating how many notebooks and pencils you need. If you know you have 5 classes and you need 2 notebooks per class, that's 5 x 2 = 10 notebooks.
Well, usually in the story, kids might first put on their school uniforms. That's a very common step. Then they would pack their school bags with books, notebooks and pens.
Addition and subtraction often come up. Like in a story where veterans are pooling their resources. If one veteran has $100, another has $50 and they need to buy supplies that cost $120. First, find the total they have which is 100 + 50 = 150. Then subtract the cost of supplies 150 - 120 = 30. So they have $30 left. And this simple addition and subtraction can be part of a mystery like finding out if they can afford more supplies later.
One good elementary school math story could be about the discovery of zero. Long ago, people didn't have the concept of zero. But as civilizations grew and trade became more complex, they realized they needed a symbol to represent 'nothing'. So, the idea of zero was born. It was a huge step in math as it allowed for more complex calculations and number systems to develop.
One high school math story could be about a student who was really struggling with geometry but then had a great teacher who used real - world examples like architecture to make it click. The student went from failing to getting an A in the class.
In junior high school, a person's math score couldn't directly measure a person's math ability. Mathematics was a subject that required continuous learning and practice. Different people might have different performances in mathematics in junior high school. Generally speaking, students with good math scores might get higher math scores in junior high school. However, the score was not the only measure. It also needed to consider the student's ability to solve problems, comprehension ability, thinking ability, and other factors. Therefore, for junior high school students, the number of marks needed to be considered. There were many factors to consider, and they could not simply give a standard. The most important thing was that students should focus on learning and understanding mathematics to continuously improve their mathematical ability and level.
Geometry is also a possible concept. When building a gingerbread house, the shapes of the pieces and how they fit together are geometric. The walls are rectangles, the roof might be triangles, and making sure they all connect properly involves geometric understanding. Also, if the story has a scene where people are arranging Christmas trees in a pattern in a town square, that's related to geometry too.
It makes math more interesting. Plain math problems can be dull, but when presented as a story, it grabs students' attention.
They make math more interesting. For example, instead of just learning dry formulas, in a math fiction book, the concepts are presented within a story, like in 'The Number Devil' where the devil shows the boy math in a magical way.
