About snappi

I am a math teacher in a secondary school in Italy. I am involved in projects that meet the real needs and challenges of both society as a whole and local communities. I am a Scientix Ambassador and I'm a territorial trainer of the mathematics and reality "M&R" project .

“Speaking numbers” and their use – Part 2.

Teaching in distance

Teachers: Sabrina Nappi in collaboration with Mario Di Fonza and Riccardo Di Pietro

Students: 14-16 years

DESCRIPTION: Analysing situations and problems of daily life with the aim of their mathematical formalization, we naturally introduce mathematical concepts.

This blog post represents the second part of the blog post on ‘Speaking number’ because it develops the challenges that the students have created after having studied statistics and the use of its tools.

Statistics: Sustainable development goals 

Exercises about sustainable development goals of the Agenda 2030

After watching the introductory video about sustainable development goals, students will solve the exercises. When they are done with that, the following activity will be a mutual challenge in groups about creating problems whose structure is the same one as the sustainability themes previously carried out. They will develop this activity focusing on goals number 2,5,12,13.

“Speaking numbers” and their use

Teaching in distance (still in progress).
Teachers: Sabrina Nappi in collaboration with Mario Di Fonza and Riccardo Di Pietro
Students: 14-16 years

DESCRIPTION:
Analysing situations and problems of daily life with the aim of their mathematical formalization, we naturally introduce mathematical concepts and tools. Reading and interpreting data in a chart or, vice versa, filling in a chart with provided data, is not always so easy for our students.  

Introduction to statistics 

The starting point of the activity is the question “What does statistics study?” that we ask the students using the software “Mentimeter”.


Students reflect on the topic and make a list of some examples with statistics statements: “The average mark in maths in this class is 6”, “The average height of the students is 1.67 cm”, “Making pizza at home is a very trendy habit this year”.

Statistics helps us to move on from the outstanding variability of phenomena (economical, demographic, social ones etc.) to interpretive models of the surrounding reality, going through classification and abstraction.
