• ### Kindergarten Math

In Kindergarten, students practice counting objects in sets, and they think about how numbers are ordered by showing the numbers on the number line. As they put together and take apart simple numbers, students lay groundwork for learning how to add and subtract. Students learn how joining (addition) and separating (subtraction) leads to adding and subtracting. Working with patterns helps to strengthen this understanding of addition and subtraction and moves them toward development of algebraic thinking. Kindergartners develop basic ideas related to geometry and they name simple two- and three- dimensional figures and find these shapes around them. Students sort and match shapes as they begin to learn classification skills.

In kindergarten math, your child will:

• count objects and tell how many there are
• write numerals 0-20 compare numbers or sets of objects to tell which has more or less
• add & subtract quickly and easily to 5
• add & subtract within 10 using objects, fingers, drawings, numbers, or equations
• solve addition and subtraction story problems
• understand that teen numbers are 10 and some more
• identify and describe shapes
• understand length and weight as something that can be measured

Learning Across the Year Kindergarten Summary

### 1st Grade Math

In first grade, students continue to work with whole numbers to quantify objects. They start to develop critical concepts of ones and tens that introduce them to our base ten number system. An understanding of how ones and tens relate to each other allows students to begin adding and subtracting two-digit numbers. Understanding that addition and subtraction undo each other is an important part of learning to use the operations efficiently and accurately. Students start to learn about measurement by measuring length. They begin to understand what it means to measure something, and they develop their measuring skills using everyday objects. Students expand their knowledge of two- and three- dimensional geometric figures by sorting, comparing and contrasting them according to their characteristics.

In grade 1 math, your child will:

• solve addition and subtraction story problems
• count by ones and tens to 120 read and write numbers to 120, and represent a number of objects up to 120 with a written numeral
• understand place value by describing what the digits mean in two-digit numbers; use this knowledge to add and subtract
• add two-digit numbers using at least two different strategies and explain how the strategies work
• subtract two-digit numbers that are multiples of 10 using at least two different strategies and explain how the strategies work
• compare two numbers using the symbols >, =, and <
• add and subtract numbers within 10 efficiently and accurately
• read or construct a graph and answer questions about the data
• measure length using non-standard units such as Popsicle sticks, linking cubes, and so on
• tell and write time to the hour and half-hour on analog and digital clock

### 2nd Grade Math

In second grade, students refine their understanding of the base ten system and use place value concepts of ones, tens, and hundreds to understand number relationships. They become fluent in writing and renaming numbers in a variety of ways. Students focus on what it means to add and subtract as they become fluent with single-digit addition and subtraction facts and develop addition and subtraction procedures for two-digit numbers. Students make sense of the procedures by building on what they know about place value and number relationships and putting together and taking apart sets of objects. Since students are well acquainted with two-digit numbers by this point, they tell time on different types of clocks, as well as identify coins and determine the value of a collection of coins. Students make predictions and answer questions about data as they apply their growing understanding of numbers and the operations of addition and subtraction. Students understand the process of measuring length and progress from measuring with objects such as toothpicks and craft sticks to the more practical skill of measuring length with standard units and tools.

In grade 2 math, your child will:

• solve two-step addition and subtraction story problems to 100
• add and subtract to 20; know addition facts to 20 by memory
• read and write 3-digit numbers using numerals, words, and expanded notation (726 = 700 + 20 + 6)
• understand that the three digits of a 3-digit number represent amounts of hundreds, tens, and ones
• use symbols >, =, < to compare two 3-digit numbers
• add and subtract 2-digit numbers accurately and efficiently, and explain strategies for doing so
• add and subtract 3-digit numbers using models, sketches, and/or numbers, and explain strategies for doing so
• estimate and measure length in centimeters and meters, inches and feet.
• divide circles and rectangles into two, three, and four equal parts and describe the parts
• recognize, draw, and analyze 2- and 3-D shapes
• solve money problems involving dollars, quarters, dimes, nickels, and pennies

### 3rd Grade Math

In third grade, students solidify and formalize important concepts and skills related to addition and subtraction. They extend critical concepts of the base ten number system to include large numbers and formalize procedures for adding and subtracting large numbers. Students learn the meaning of multiplication and division and how these operations relate to each other. With a solid understanding of these two key operations, students are prepared to formalize the procedures for multiplication and division in grades four and five. Students learn about fractions and how they are used. Students deepen their understanding of fractions by comparing and ordering fractions and by representing them in different ways. Students learn about lines and use lines, line segments, and right angles as they work with quadrilaterals. Students connect this geometric work to numbers, operations, and measurement as they determine simple perimeters.

### 4th Grade Math

In fourth grade, students learn basic multiplication facts and efficient procedures for multiplying two-and three-digit numbers. They explore the relationship between multiplication and division as they learn related division and multiplication facts in the same fact family. These skills, along with mental math and estimation, allow students to solve problems that call for multiplication. Students solidify and extend their understanding of fractions to include decimals. They learn how to find the area of a rectangle as a basis for later work with areas of other geometric figures. Students work with common factors and multiples as preparation for learning procedures for fraction operations in grades five and six.

### 5th Grade Math

In fifth grade, students learn efficient ways to divide whole numbers. They apply what they know about division to solve problems, using estimation and mental math skills to decide whether their results are reasonable. Students focus on triangles and quadrilaterals to formalize and extend their understanding of these geometric shapes. Students continue their development of algebraic thinking. They use variables to write simple algebraic expressions describing patterns or solutions to problems. They extend their work with common factors and multiples as they deal with prime numbers. Students extend their knowledge about adding and subtracting whole numbers to learning procedures for adding and subtracting fractions and decimals. Students apply these procedures to solve a wide range of problems that involve more of the types of numbers students see in other school subjects and in their lives.

### 6th Grade Math

In sixth grade, students multiply and divide fractions and decimals with conceptual and procedural understanding. Students extend their knowledge of fractions to develop an understanding of what a ratio is and how it relates to a rate and percent. Students extend what they know about area and perimeter to more complex two-dimensional figures including circles. They find the surface area and volume of simple three dimensional figures. Order of operations is introduced and students learn about negative numbers. They write and evaluate algebraic expressions and write and solve algebraic equations. By developing an understanding of ratio in real-life contexts, students learn how it relates to rates and percent.
