Math Common Core


The new math standards focus on comprehensive learning, which means that learned skills will build upon one another as a child advances onto the next grade. 

Children will practice and model complex problem solving through applying what they've learned to every day situations. Since the standards build upon one another from year to year, children will have deeper understanding of foundational math concepts and equations, resulting in real learning. In addition, the goal will be to tie these skills and concepts to real life. For example, one of the ways parents can work with their child at home could be to have them double, triple, or halve a recipe. 


In kindergarten, your child will focus primarily on two important areas. 

The first is learning numbers and what numbers represent. The second 

is addition and subtraction. Students will also learn to identify and work 

with shapes. Activities in these areas include:

• Counting how many objects are in a group and comparing 

the quantities of two groups of objects

• Comparing two numbers to identify which is greater or less than the 


• Understanding addition as putting together and subtraction as taking 

away from

• Adding and subtracting very small numbers quickly and accurately

• Breaking up numbers less than or equal to 10 in more than one way 

(for example, 9=6+3, 9=5+4)

• For any number from 1 to 9, finding the missing quantity that is 

needed to reach 10

• Representing addition and subtraction word problems using objects or 

by drawing pictures

• Solving addition and subtraction word problems involving numbers 

that add up to 10 or less or by subtracting from a number 10 or less



 In grade one, students will work with whole numbers and place value—

including grouping numbers into tens and ones as they learn to add 

and subtract up through 20. Students will also use charts, tables, and 

diagrams to solve problems. Activities in these areas will include:

• Quickly and accurately adding numbers together that total up to 10 or 

less and subtracting from numbers up through 10

• Understanding the rules of addition and subtraction (for example, 


• Solving word problems that involve adding or subtracting numbers up 

through 20

• Understanding what the different digits mean in two-digit numbers 

(place value)

• Comparing two-digit numbers using the symbols > (more than), 

= (equal to) , and < (less than)

• Understanding the meaning of the equal sign (=) and determining if 

statements involving addition and subtraction are true or false (for 

example, which of the following statements are true? 3+3=6, 4+1=5+2)

• Adding one- and two-digit numbers together

• Measuring the lengths of objects using a shorter object as a unit of 


• Putting objects in order from longest to shortest or shortest to longest 

• Organizing objects into categories and comparing the number of 

objects in different categories

• Dividing circles and rectangles into halves and quarters



In grade two, students will extend their understanding of place value 

to the hundreds place. They will use this place value understanding 

to solve word problems, including those involving length and other 

units of measure. Students will continue to work on their addition 

and subtraction skills, quickly and accurately adding and subtracting 

numbers up through 20 and also working with numbers up through 100. 

They will also build a foundation for understanding fractions by working 

with shapes and geometry. Activities in these areas will include:

• Quickly and accurately adding numbers together that total up to 20 or 

less or subtracting from numbers up through 20

• Solving one- or two-step word problems by adding or subtracting 

numbers up through 100 

• Understanding what the different digits mean in a three-digit number

• Adding and subtracting three digit numbers

• Measuring lengths of objects in standard units such as inches and 


• Solving addition and subtraction word problems involving length 

• Solving problems involving money

• Breaking up a rectangle into same-size squares

• Dividing circles and rectangles into halves, thirds, or fourths 

• Solving addition, subtraction, and comparison word problems using 

information presented in a bar graph


• Writing equations to represent addition of equal numbers
