Ralleia Experimental Primary Schools

Math Lessons with Operations: Fractions the structure, the concept, depiction

Teacher: Develegka Maria - Karousatou Maria

Class: E2

1st lesson (some parts are in Greek)

2nd Scratch Lesson (some parts are in Greek)

Most of the students had a very good knowledge about these concepts. However, the scratch projects immediately resulted an increased attention of students. The concept of the "whole" immediately became noticeable initially of the uncut pizza and after with the cut one. They easily answered the questions. All the students participated to this lesson. Then easily students express the pieces of pizza to fractions.

While sometimes the images and questions could be perceived as something childish, on the contrary the teacher of the specific lesson realized that images and questions attributed the simplicity, the clarity and precision that always should characterize mathematics.

The next stage, which included a return to the whole (unit)  by adding fractions, was completed  by repeating the questions and of course by depicting the pieces and the whole. It was easily understood that by joining the pieces we can "create" the whole again. To sum up, the simple examples helped the students to thoroughly understand the concept of fractions, so that they can handle them more confidently in more complex operations.
