Children do not start learning math when they are first taught about numbers. Rather, math learning starts with concepts of quantity, size and comparisons, and the words that represent numbers. Math learning starts with counting physical objects with caretakers, understanding concepts of less and more or full and empty by playing with food or toys,...
As students get older, they are presented with what are often referred to as “word problems.” These are math problems placed within the context of a written scenario. While the connection between reading difficulties and completing math word problems can be clear, it is important to consider how language plays a role in understanding these types of...
Awareness of the role of language in math can help teachers think diagnostically about where a student is getting “stuck” in math. While we tend to focus on the domain specific skills of mathematics, it is important to consider that the aspects tripping a student up might be skills we don’t typically think of as necessary for math learning. Here ar...

Overall, algebra is the math of symbols and numbers. Equations find missing values, expressions describe values, and functions show how things relate. These concepts are essential for solving problems and making decisions in many different fields. Algorithm.
In brief, these are terms that are generally accessible to most, yet still provide us with a glimpse of the world of non-miniaturized mathematics — and the way their practitioners act and think.
- absolute value - The absolute value of a number is the distance from the origin on a number line. For example, the absolute value of 2 is 2 (written |2|=2).
- algebra - Algebra is the study of generalized arithmetic. In algebra, unknown numbers can be represented by letters in order to solve equations. For example, 4 + x = 10 is true for x=6.
- coefficient - In an expression or equation, a coefficient is a number in front of a variable. For example, in the expression 8x, the coefficient is 8 (and the variable is x).
- degree of a polynomial - The degree of a term within a polynomial is the sum of the exponents of variables that occur in that term (if there is no exponent written on a variable, such as in 3x, the exponent is one).
