[1eso] Algebra: algebraic language, equations

Here you can find the materials to develop 14 sessions on algebra (55 minutes/session)
Topics worked: algebraic language, algebraic expressions, creating formulae, numerical value, operations with algebraic expressions, equivalent equations, solutions, first degree equations, solving problems.
Some exercises are taken from a selection made by J.A. Trevejo from Australian text books Mathematics for the International Student, Haese & Harris Publications, 2008.
