Matemáticas: Álgebra Suma y resta de términos iguales

What will be taught:
Students will learn how to add and subtract like terms that have the same literal coefficient represented to the same power but do not necessarily have the same numerical coefficient. 
Students will learn how to organize the problems when performing the arithmetic operations on polynomials. Students learn how the terms should be arranged in descending and ascending powers of the literal coefficient. 
Students will learn how to tell like terms.
Students will practice solving like terms by adding and subtracting.
How will the lesson be taught:
Whiteboard, slides, engagement, discussions. 
Some knowledge of basic math.
