The use of interactive resources in teaching mathematics at school is becoming
increasingly relevant in modern education. This is due to the fact that such services
can not only help consolidate mathematical knowledge, as well as practical skills
necessary for successful work in the modern information society, but also allow
students to independently explore mathematical objects, apply the acquired
knowledge in practice and track their progress. In addition, the use of such resources
helps to attract students'
attention to the lesson, making it more interesting and
understandable.
One of the most important practical skills that can be developed through
interactive resources is the ability to work with information in different forms. The
modern world places high demands on people to process and analyze large volumes
of data, so students who learn to use interactive resources to work with data will be
prepared to work in the modern information society.
The Desmos graphing calculator is a powerful and convenient tool that can be
used in a variety of cross-curricular projects at the intersection of mathematics and
other subjects. The service provides many tools that can be used to create graphics,
models, and animations. This allows teachers and students to consider mathematical
concepts not only in a theoretical
but also in a practical sense, which can make the
study of mathematics more interesting and exciting, and show its beauty.
Visualization effects contribute to a more solid assimilation of mathematical
knowledge, and interactivity increases the degree of student involvement [1], [2].
One of the interesting and non-trivial ways to use the Desmos service is the
implementation of educational assignments and interdisciplinary projects in
mathematics, visual arts and culture. The point of the project is to create illustrations,
images and even animations related to cultural and architectural monuments, using
mathematical tools - graphs, equations and inequalities,
built-in functions and
independently created dependencies. This method of synthesizing different areas of
activity - mathematics and fine arts and the culture of the native land - usually
arouses keen interest among schoolchildren [3]. This form of work as a type of
project at different levels of complexity can be offered to students of middle and high
school age.
Let's look at the Desmos calculator tools that can be used in such projects.

A large set of standard mathematical functions and equations allows you to
depict a variety of lines - straight lines, curves of the second and higher orders,
sinusoids, etc. The use of explicitly specified restrictions on the domain of definition
and the range of values makes it possible to use segments of graphs of different types.
Strict and non-strict inequalities allow you to depict closed and shaded areas of
different shapes.
The Table component allows you to define a polyline (a
group of points
connected by segments); if necessary, you can use additional settings to move the
nodes of the polyline, creating the desired contours. The Polygon tool, using a group
of points specified by a table, allows you to construct a filled polygon. The ability to
fine-tune the coordinates of points in Desmos allows you to create quite complex
contours of geometric shapes.
Knowledge about the coordinates of symmetrical points allows you to create
symmetrical objects, the use of lists - groups of repeating shapes, ornaments.
Additional features of Desmos include the following:
the ability to add parameters to equations and functions, which allows you to
“revive” created pictures, add moving objects, creating an animation effect;
the ability to set your own colors using the rgb function, which allows you to
touch on the issues of color coding in the RGB color model and connect this with the
study of computer science;
interactivity and speed of work - Desmos allows you to instantly change
image parameters and observe changes in real time, which
makes the work process
more interactive and fun;
accessible and free - Desmos is a free online service available to all users
from any device with an Internet connection.
The described capabilities of the Desmos calculator can be used to develop
practical skills in mathematics and computer science, in independent educational and
research work of students. Desmos enables students and teachers to use mathematical
tools to create interactive visualizations and demonstrations that help students better
understand and analyze complex concepts and ideas.
The idea of “drawing” images using mathematical means seems quite
interesting to us. In such cases, the tools of mathematics and information technology
can become an educational and developmental tool.
As part of the study of the history and culture of the native land, you can offer
photographs and models of architectural monuments of your city as samples for
implementation, which will allow you to connect together familiarity with the culture
of your native land and knowledge from the field of mathematics and information
technology. A similar educational task was proposed for
completion by students of
the Faculty of Physics and Mathematics of Smolensk State University in the direction
of “Pedagogical Education”.
In the example in Fig. 1, the contours of one of the architectural monuments of
Smolensk - the Smolensk Church - are depicted using double inequalities. In the
construction field there is a photo of the building for a sample.
