# INTRODUCTION

The didactic unit treated in this report concern to Algebra of 1st ESO. Which belongs to the block 2: "Numbers and algebra".

In my opinion, Algebra is the most important branch of mathematics. Its use is present in many areas. It is very useful to simplify many works of the daily life of many professionals from engineers, architects, doctors, electricians, carpenters, etc. This provides the ability to develop a logical and algorithmic thinking to solve problems. In addition, when students make the transition from the concrete to the symbolic language of arithmetic algebra, develop abstract reasoning skills.

# METHODOLOGY

Flipped Classroom

This educational model focuses on learning in the student, making it part of their learning. Furthermore, it promotes independence and critical thinking.

Therefore, students will be provided 6 videos corresponding to the theoretical parts of the unit. To be able to check that students have accessed this resource there will be some activities within the video either by a reflection of the content, questions for the professor, who has not been understood, exercises, etc. ..

# MATERIALS

These are the materials and other resources used in this unit:

• Book of the student, the student's notebook and calculator.
• Videos
• Online Exercices
• Final exam

# ASSESSMENT

Procedures and instruments for the evaluation will be the following:

• Quizzes with questions of reflective type or of reasoning about the video of an individual assessment.
• Exercises proposed in the classroom in groups or pairs.
