4 digit addition/mississippi-standards?dictionary=addition&did=99" onclick="getAsistant(this,event,99,'addition');return false;" style="color:#009000;">addition involves adding addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers that have four digits. When adding 4 digit addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers, it is important to align the digits according to their addition/mississippi-standards?dictionary=place+value&did=677" onclick="getAsistant(this,event,677,'place value');return false;" style="color:#009000;">place value - thousands, hundreds, tens, and ones.
Steps for 4 Digit addition/mississippi-standards?dictionary=addition&did=99" onclick="getAsistant(this,event,99,'addition');return false;" style="color:#009000;">Addition:
Align the addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers vertically according to their addition/mississippi-standards?dictionary=place+value&did=677" onclick="getAsistant(this,event,677,'place value');return false;" style="color:#009000;">place value.
Start adding from the rightmost column (ones place) and move towards the left.
Add the digits in each column, carrying over to the next column if the sum is addition/mississippi-standards?dictionary=greater+than&did=18" onclick="getAsistant(this,event,18,'greater than');return false;" style="color:#009000;">greater than 9.
Continue this process for each column until all columns have been added.
Example:
Let's add the following 4 digit addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers: 3,245 + 1,678.
Practice adding 4 digit addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers using the vertical alignment method.
Learn to carry over when the sum of a column exceeds 9.
Work on problems involving carrying over multiple addition/mississippi-standards?dictionary=times&did=198" onclick="getAsistant(this,event,198,'time');return false;" style="color:#009000;">times.
Master the addition/mississippi-standards?dictionary=addition&did=99" onclick="getAsistant(this,event,99,'addition');return false;" style="color:#009000;">addition facts for single digit addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers.
With practice and understanding of addition/mississippi-standards?dictionary=place+value&did=677" onclick="getAsistant(this,event,677,'place value');return false;" style="color:#009000;">place value and carrying over, you can become proficient in adding 4 digit addition/mississippi-standards?dictionary=numbers&did=139" onclick="getAsistant(this,event,139,'numbers');return false;" style="color:#009000;">numbers!
