inequalities Course /
Level 4th (matemáticas
académicas)
1. Learning
outcomes
/ Evaluation criteria
|
Learning outcomes:
ü To factorize polynomials in order
to solve polynomial equations whose degree is greater than two
ü To express in algebraic language a
real situation, to study this situation and to solve the problem with the
appropriate algebraic tool: equation, inequality, system of equations… To
give an interpretation of the results in terms of the considered problem.
Evaluation
criteria:
ü To use correctly algebraic
language
ü To compute algebraic calculations
ü To know and apply algebraic properties.
ü To represent and analyze
situations involving mathematics using inequalities, equations and system of
equations.
ü To apply equations, system of equations and
inequalities in order to solve mathematical and real problems

2. Subject Content
|
ü Polynomial equations, equations
with the unknown in denominator (algebraic
fractions) and equations with the unknown inside a radical (irrational
equations).
ü Simultaneous linear equations
(systems of linear equations)
ü Simultaneous non linear equations
(systems of non linear equations).
ü Linear and quadratic inequalities.
Numerical and graphical solutions.
ü System of inequalities (one
variable)
ü The spreadsheet

Structures
|
Comparative Greater
than, less than, equal to, greater than or equal to,…Students will be
these structures when they are solving inequalities For example
![]()
Equal Student have to know how to use
this word as a verb and as a noun. For example the expression x=3 can be read in two
different ways
1.
X is equal to 3 (here equal is a noun)
2.
X equals 3 (and now is a verb)
Derivative words
High/height vs weigh/weight It is necessary to pay attention to these
pairs of words High is an adjective and height is a noun but to weigh is a
verb and weight is a noun. The students are usually confused about the
pronunciation and tend to pronounce height and weight in the same form. These
words are very frequent in words problems.
Long/length
Wide/width The pronunciation is different again, and student usually are
mistaken

Language skills
|
Reading, writing, listening and speaking

4. Contextual (cultural) element
|
Students will work about real situations as
sales, bank accounts, interests or bills every time it is possible
|

5. Cognitive (thinking) processes
|
LOTS (lower order thinking skills)
·
Understanding (the basic vocabulary, the methods
of solving equations)
·
Applying (the basic vocabulary and the
methods so that students can solve a particular equation)
HOTS (higher order thinking skills)
·
Analyzing (Real situations and translate
them into algebraic language)
·
Evaluating
(the quality of a work, the possibility of the obtained solutions,…)

6. (a) Task(s)
|
·
To solve equations and inequalities
·
To solve word problems
·
To apply their knowledge to a final project
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
6. (b) Activities
|
1.
Vocabulary tasks. Active watching
2.
Understanding and applying
tasks (students have to solve different types of equations and inequalities)
3.
Analyzing tasks (students solve word problems so that they have to
learn the new vocabulary, to analyze a real situation, to write this
situation in algebraic language, to solve the resulting equation, system or
inequality and finally to study if the solution fits the real situation)
4.
Analyzing Task II. A final project, in groups of three students work
with a class project. Finally they develop different strategies, use ITC,
write a report and communicate their investigation to rest of the class.

It is mainly based on the hands-on
experience at designing units and on conversations with experts and peers. The
theory of the 4Cs by Do Coyle has also been taken into account. This theory has
been shown in various publications, such as: Coyle, D., Hood, P. and Marsh, D.,
2010. Content and Language Integrated Learning. Cambridge University Press.
