Title: Integers Numbers
Subject: Mathematics
Course: 1º E.S.O.
Language: English
LEARNING OUTCOMES:
1: To know positive and negative numbers.
2: To operate with integer numbers.
3: To apply concepts real-life situations.
4: Carry out activities and tasks related to the theme of the unit using ICT.
INTRODUCTION
Integers are a generalization of the set of natural numbers that includes negative integers, in addition to zero. The fact that a number is integer means that it hasn´t got decimal part.
Negative integers can be applied in various contexts, such as the representation of depths below sea level, subzero temperatures, or debts, among others.
Its use, although with diverse notations, goes back to the Antiquity. The name of integers is justified because these numbers, already positive or negative, always represented a number of non-divisible units (for example, people).
They find application in the accounting balances. Sometimes, when the amount owed exceeded the amount owned, it was said that the banker was in "red numbers". This expression came from the fact that what we now call negative numbers were represented written in red ink.
Finally, the integers are any element of the set formed by the natural numbers (N) and their opposites. The set of integers is designated by Z:
Z = {., -11, -10,., -2, -1, -0, 1, 2,., 10, 11 ,.}
Negative numbers allow you to count new types of amounts (such as debit balances) and order above or below a certain reference item (temperatures above or below 0 degrees, the floors of a building above or below the entry to it.).

Sessions (10)
SESSION 1: INTRODUCTION OF THE TOPIC.
What are natural numbers? Representation on the number line.
1.- Perform the video viewing: https://www.youtube.com/watch?v=5oHJcmYbHvA
2.- Encourage participation in a brainstorming session, with the aim of finding out prior knowledge:
- What do you know about natural numbers?
- What do you know about whole numbers?
- What kind of number is ...?
- What is the result of ...?
- What do we have to do to solve ...?

https://www.mathgoodies.com/lessons/vol5/challenge_vol5
https://es.scribd.com/document/175992931/Integer-Numbers
Resolution of the problems that appear in the topic, from page 21 onwards.
2.- Realization of problems of own production, resolving them and exposing them to the class, following the scheme of:
* Data that the problem gives me.
* Data that the problem asks me.
* Operation to be performed.
* Problem solution.
The problems will be related to subjects that interest the students, such as:
https://docs.google.com/document/d/13wNODkdaYwME76YsYU44H_g3Ol529KyiU6hmPgyWYHA/edit
- Each student elaborates a problem and exposes it to the class.
- Use keywords, for instance: temperature, save/pay, tv show / win or lose, benefits / losses…
- Fix the solution, for example: the temperature variation was…, I have won/lost…
