How to determine the Context of Mathematical Expressions- Equations are basically a pure and symbolic expression of entities, most of the time. The idea of an equation is almost always about finding a solution to a problem through symbol manipulation. Every single manipulation, if done according to the conventional rules, can lead to an equivalent equation which is relatively simpler (easier to solve) compared to the previous one. Another way of solving such equations is through making a graphical representation of them. This, however, is a much more symbolic approach to solving a mathematical equation. This doesn't determine the concept of all equations. You can always think of a story for explaining an equation. Work on developing stories that can help in: Enliven the math equations. Allowing the students to make sense of what is happening in the situation that makes up the equation. Make proper distinctions between constants and variables and how their relationship can be changed if assumptions are changed midway. These worksheets and lessons show students how to breakdown and understand all aspects of math expressions including coefficients, factors, and terms. We also go as far to see how these elements interact and effect the outcome of the problem.

### Printable Worksheets And Lessons

- Understanding a Polynomial Step-by-step Lesson- Learn the numbers of terms, degrees, and classification of an expression.

- Guided Lesson - We build on the lesson a great deal and leave you determining your classification of expressions.

- Guided Lesson Explanation - This will give you a solid understanding of the concepts of this section.

- Practice Worksheet - This one might be a bit easy for most, but you surely will know the concept of highest degrees.

- Matching Worksheet - More degree work here. I will diversify the new sheets I add to this section better.

#### Homework Sheets

Time to breakdown expressions and their parts. Make sure to review your expression vocabulary first.

- Homework 1 - Each piece of the polynomial is a term, as you see above. This polynomial has 3 terms.
- Homework 2 - Whichever term is to the highest power is also to the
highest degree. 2x
^{3}is to the highest degree. - Homework 3 - The degree of the overall polynomial is represented by the term that is to the highest degree.

#### Practice Worksheets

Many students still have a problem identifying expressions as mono, bi, or even polynomials at this level.

- Practice 1 - How many terms are in the polynomial?
- Practice 2 - What is the degree of the polynomial?
- Practice 3 - Which would be the best classification of this expression?
