Unidad 1 de preálgebra: Operaciones con números reales

In this class, students will be gently introduced to some foundational Pre-Algebra concepts. Students will be introduced to the concepts listed below, and will have practice opportunities. This class is a supportive environment where students can become familiar and comfortable with Pre-Algebra topics.

This class is the first in a Pre-Algebra series. I can be taken alone, or followed by Pre-Algebra Unit 2: Algebraic Expressions. Here is the link to the next class: https://outschool.com/classes/pre-algebra-unit-2-algebraic-expressions-vWzTK6GO


Topics covered in each of the ten meetings include:

1st Meeting: Absolute value and adding positive and negative numbers

2nd Meeting: Subtracting positive and negative numbers

3rd Meeting: Multiplying and dividing positive and negative numbers

4th Meeting: Reducing fractions, mixed numbers and improper fractions, converting between fractions, decimals, and percents

5th Meeting: Adding and subtracting fractions

6th Meeting: Multiplying and dividing fractions

7th Meeting: Simplifying expressions with powers and roots

8th Meeting: Order of Operations

9th Meeting: More Order of Operations

10th Meeting: Evaluating expressions with a given variable replacement



Background Knowledge:  Students should be fluent with basic math operations, including addition, subtraction, multiplication, and division. Students should have also previously studied adding, subtracting, multiplying, and dividing fractions, although these skills will be reviewed in Lessons 5 and 6.


Guided notes and practice problems will be provided for each session. All you need is access to a printer.   

During class, the I will guide students through the provided guided lecture notes following an "I Do, We Do, You Do" format.  Students will first take notes while I explain each method. Then, students will have an opportunity to practice applying the method with a lot of teacher support. Finally, students will practice applying the methods on their own by completing a homework assignment. Time is set aside at the beginning of class to ask questions and get help on homework problems.
