Did you know that you started doing Algebra, Geometry, Statistics, and problem solving...even in preschool and Kindergarten

Take a peek at the five different kinds of Math we've listed and see if you recognize how much you've learned.

#### What is Algebra?

Algebra is all about patterns. When you first start learning in school, you learn how to sort and classify objects according to similar attributes, or things that are alike about them. How many boys are there in the class, how many blocks are red, etc. This is the beginning of algebra Then you learn to recognize the meaning of equality, using an equal sign in between two equations (ex. 4+2=3+3). Manipulating the numbers on either side of the equal sign is kind of fun Finally, you learn about variables, coefficients, terms and equations.

#### What is Geometry?

When you first learn geometry you start with basic two dimensional shapes and how they relate to one another. Are things next to each other, below the stairs, etc Along with geometry, you usually learn measurement. You start learning how to measure right away. You measure time when you do the calendar in kindergarten and money when you learn how much a quarter is worth. As you learn to measure time, distance, weight, money, and temperature, you also are learning to compare items As you go from grade to grade in school what you learn to measure gets harder as does what you compare. The geometric shapes you learn go from squares and circles, to rays and lines and finally you learn three dimensional shapes and other geometrical concepts. You will be plotting numbers on a graph and measuring the angles and perimeters and areas of objects in no time.

#### What is Number Sense?

Number sense is learning about how numbers work with other numbers and what they mean. When you first learn about numbers, you learn how to count, about ordinal numbers, how to group numbers and break them up fractionally and how to represent them in percent form. As you get older you learn how to round them and estimate and how to figure out what the place value of a number is. You learn how to write numbers as decimals and what their relationships are in fact sentences. You learn about prime numbers, whole numbers, rational numbers, integers and square roots. Finally you learn what the order of operations is and all about scientific notation. These things help you to make sense of what the numbers are and how to use them when doing computations.

#### What is Problem Solving?

Problem solving is when you figure out problems with numbers. Adding, subtracting, multiplying and dividing. Figuring out problems using fractions, decimals, mixed numbers, regrouping, word problems, etc. Sometimes Problem solving is also called mathematical reasoning. In fact it can be any kind of 'problem' that you need to work on or reason out When you first start learning, you actually start doing statistics. When you looked around yourself in kindergarten class and counted how many boys were in your class and how many girls, you were gathering data. You gather data familiar to you and learn about counting and tallyingYou learn how to read and construct graphs, line plots, etc and to show the the results you organized. You use easy spinners and tiles and cubes to make predictions and analyze data. This is all statistics and probability. As you go through school, the gathering gets a little harder and the graphs get more detailed, but the concept is the same.
