## Elementary School

## Grade 6 - Oregon Common Core State Standards of Mathematics

## A Sample of What Your Child Will Be Working on in 6th Grade

**Understanding ratios and rates, and solving problems involving proportional relationships (e.g., if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?)

**Dividing fractions and solving related word problems (e.g., how wide is a rectangular strip of land with length ¾ mile and area ½ square mile?)

## Grade 5 - Oregon Common Core State Standards of Mathematics

## Main Focus

**Fluency with fractions, mainly addition and subtraction. Limited amount of multiplication and division.*

*EXAMPLES: ***Like denominators** (bottom numbers)

Steps to solve

- add top numbers
- bottom stays the same
- reduce all fractions to simplest form
- 2/3 + 2/3 = 4/3 then reduce to 1 1/3

**Unlike denominators**

Steps to solve

## Grade 4 - Oregon Common Core State Standards of Mathematics

## Place Value

- Know place value up to one million.
- Know multiplication – arrays, equal sized groups, area models
- Distributive property
- 4-digit by 1-digit problems
- Factors and multiples
- Generate and analyze patterns
- 2-digit by 2-digit problems

- Use
**ALL**operations with whole numbers to solve problems (word problems, multi-step word problems)__4__

## Grade 3 - Oregon Common Core State Standards of Mathematics

In grade 3 there are four critical areas of focus:

- Multiplication and division up to 100
- Fractions, especially unit fractions (1/2 1/3 ¼ …)
- Rectangular arrays and area
- Two-dimensional shapes… describing and analyzing them

More specific objectives are:

## Grade 2 - Oregon Common Core State Standards of Mathematics

## Operations & Algebraic Thinking

- Understand and solve problems involving addition and subtraction.
- Use addition and subtraction within 100 to solve one- and two-step word problems.

- Add and subtract within 20.
- Fluently add and subtract within 20 using mental strategies. By the end of Grade 2, know from memory all sums of two one-digit numbers.
- Determine whether a group of objects (up to 20) has an odd or even number of members.

## Kindergarten - Oregon Common Core State Standards of Mathematics

## Counting and cardinality:

- Know number names and the count sequence.
- Count to 100 by ones and tens
- Count forward beginning from any number
- Write numbers from 0 to 20. Represent numbers with objects.

- Count and tell the number of objects.
- Understand the relationship between numbers and quantities: connect counting to cardinality.

## Grade 1 - Oregon Common Core State Standards of Mathematics

## Operations and Algebraic Thinking

- Use addition and subtraction to solve story or "word" problems.
- Use basic math operations such as +,- to solve basic math equations.
- Add and subtract sums to 20.
- Understand when a math problem is equal or not equal.
- ex) 2+3 = 5 +0 or 2+3 ≠ 6+2

- Determine the missing number in a math equation.
- ex) 7+?=9 or 5=?-2
