Instructor: Marissa Baranauskas
Learn about the state standards for math in Missouri. Find out what content is presented at each grade level, and become familiar with resources that can help students in grades K-12 understand the concepts required by these standards.

## State Standards for Math in Missouri

The 1996 Show-Me Standards were used as a reference to develop the current Missouri Learning Standards, which outline general academic achievements for students in nine subject areas, including mathematics. These standards provide a framework for what knowledge students should know, and the skills they should be able to demonstrate after completing each grade level.

## Elementary Math Standards in Missouri

This Math for Kids course can be used to reinforce math topics students should be taught in K-5 elementary school classes. The ready-made quizzes and exams are a handy way to gauge students' understanding of mathematical concepts.

### Kindergarten

Kindergarten students should learn how to count to 100 and be able to determine numbers of items. Standards require them to be introduced to the addition and subtraction of numbers 1 through 10, and have an understanding of how these smaller digits can be combined to form numbers 11-19. They also need to learn the basics of two- and three-dimensional shapes.

In 1st grade, students should be able to count up to 120 and learn how two-digit numbers are formed. They need to add and subtract numbers 1-20, and apply these concepts to word problems. Students should understand how the lengths of objects differ through side-by-side comparisons. They need to know how to build models to represent shapes and divide them into parts. Lessons at this grade should also cover time in increments of half hours and hours.

2nd graders should further develop their addition and subtraction skills using numbers 1-100, and use mental methods to add and subtract numbers 1-20. They need to learn how to identify even and odd amounts of items by grouping them into pairs. Students should also be able to count to 1,000 and understand how three-digit numbers are formed. They need to use tools to measure objects and become familiar with using the concept of money in word problems.

Students in the 3rd grade need to be able to multiply and divide numbers up to 100. They should learn how to apply the order of operations when solving math equations. Students must become familiar with rounding numbers and fractions. Lessons should teach students how to tell time in minutes and understand more advanced measurement types, such as volume, mass, and area.

4th graders need to learn to follow rules to make numerical and geometric patterns, and use symbols to represent relationships between numbers, fractions, and decimal quantities. They should also be introduced to factors and multiples. Furthermore, they need to learn how to convert between units of measurement, and identify angles on geometric shapes.

5th grade students must learn how to use parentheses in mathematical equations, and examine and combine fractions and decimals of extended place values. Students should also be able to use graphing skills and convert units of measurement to find solutions to real-life scenarios.

## Middle School Math Standards in Missouri

As mathematical concepts advance by grade level, teachers may need helpful tools to not only teach their students but keep them engaged. The following information includes specifics on Missouri math standards for middle school and resources teachers can use in class and as homework assignments that meet all of these needs.

Students in the 6th grade should be introduced to ratios, multiplication and division of fractions, and identification of common factors and multiples of numbers. Students also need to be able to understand the concepts of positive, negative, and rational numbers. Furthermore, they should begin to implement variables into mathematical equations and gain a basic understanding of statistics. Use these full courses or individual lessons within them to supplement classroom curriculum:

7th graders need to be able to examine relationships between proportions and use this to solve word problems. They should learn multiple ways in which mathematical relationships can be expressed, and how to solve equations with several variables. Students should be able to represent geometric concepts with drawings to solve problems. They also need to be able to expand on statistical concepts such as sampling, probability, and making assumptions. The following courses can be used as supplementary teaching and learning tools:

8th grade students should be introduced to irrational numbers, radicals, and exponents. They need to be able to demonstrate linear relationships in mathematical equations. Eighth graders need to learn how to solve linear problems that contain up to two variables. Furthermore, they need to know how to consider the principles of congruence and translation as it applies to geometric figures, and be introduced to the Pythagorean Theorem. The following courses contain lessons that cover all of the concepts required by the standards, and they each contain short and entertaining lessons as well as lesson quizzes and more comprehensive exams:

## High School Math Standards in Missouri

At the high school level, math concepts are more distinctive and advanced. The following sections outline the instruction students should receive by the end of their high school years. Each section also includes resources to help students learn these advanced concepts in an easy and engaging way, or that teachers can use to introduce students to these math concepts in the classroom.

### Number and Quantity

Exponents, rational, and irrational numbers previously learned need to be expanded at the high school level. The application and selection of appropriate units of measure should also be learned. Students need to know how to graph and solve equations using complex numbers, different powers, and more than two algebraic expressions. They should also learn about vectors and matrices. Lessons in the High School Standards: Number & Quantity course cover all of these topics and more to ensure high school graduates understand the required material.

### Algebra

At the high school level, students need to learn how to describe complex numerical expressions and translate words into mathematical equations. They should be able to find zeros of polynomial equations, and learn how to solve and graph inequalities. Students can further review algebra concepts using lessons from the High School Math Standards: Algebra course, or teachers can use them to create or supplement daily lessons.

### Functions

The ideas of domain and range should be applied to functions at the high school level. Students need to learn to use functions to solve problems and represent various types with graphs. The functions that students must be exposed to include linear, exponential, quadratic, and trigonometric. The High School Math Standards: Functions course provides short lessons that make learning these concepts easy and fun.

### Geometry

Students in high school need to learn how to make transformations of shapes and lines in the plane. They also need to be able to verify theorems of circles, triangles, parallelograms, lines, and angles. Additionally, students should know how to demonstrate their ability to illustrate geometric concepts and define them with equations. Students can further develop their understanding of these concepts using the High School Math Standards: Geometry course.

### Statistics and Probability

At the high school level, students should be introduced to both quantitative and categorical types of data, and be taught how to use statistical concepts to explain conclusions. They also need to know how to use probability to predict the occurrence of events and outcomes. Students and teachers can both benefit from the lessons and quizzes included in the High School Math Standards: Statistics & Probability course.
