Author: Julija Aidukonienė
School: Kalesninkai L. Narbutas gymnasium
Intended for grade: 5
Lesson idea: Create a drawing based on the cubism art movement. During the lesson, techniques learned during the course are utilized. The work of Pablo Picasso, a renowned pioneer of the cubism movement, inspires the geometry lesson through practical application, recognizing and depicting acquired geometric knowledge.
Course of the lesson:
Introduce the art movement of cubism and its most prominent creator – Pablo Picasso. Using examples of artworks, familiarize how the artist depicted reality by employing geometric shapes.
In the examples, identify the geometric shapes learned in the lesson and their representation on a plane.
Mathematics
Assign a creative task – to look at the objects around us through the prism of geometric shapes and create a drawing in the style of cubism.
Time for independent completion of the task.
Presentation and discussion of the works.
Summary of the lesson and its outcomes.
Reflection: Invite to explore the surroundings after the lesson and notice the geometric shapes that make up the objects in our environment.

Better to have no money than to be in debt. Comparing positive and negative numbers
Author: Ala Jonušienė
School: Jonava Raimundas Samulevičius progymnasium
Intended for grade: 6
Lesson idea: Preparing the lesson plan was inspired by the economist Aleksandras Izgorodinas. When discussing economic situations in public spaces, the visionary uses apt examples, speaking about complex matters in a simple, clear, and understandable way. That's exactly how I'd like to convey mathematics to sixth graders. The lesson plan was developed using the technique of stepping into another's shoes.
Lesson plan:
The topic is explained using the concept of money and incorporating the visionary's commentary:
1. Comparison of zero and a negative number:
"It's better to have no money than to be in debt."
0 > –57
2. Comparison of a positive and a negative number:
"It's better to have capital than to be in debt."
+25 > –4
3. Comparison of two negative numbers:
"It's better to have a smaller debt."
–7 > –25
