Reflection: Modeling Review: Multi-digit Addition - Section 3: Share/Discuss/Analyze Solution(s)

Review is very important when it comes to taking the end-of-the-year test.  Several skills are taught early in the shool year and may not be utilized much after that time.  With this particular skill, the students revisit adding multi-digit numbers using place value.  I feel that it is very important for the students to use the place value chart with this skill.  At the beginning of the school year, I noticed how some of the students did not line their numbers up correctly when adding.  For example, the student may have added a number in the tens place with a number in the hundreds place because the numbers were lined up incorrectly.  By modeling with the place value chart, it taught the students two things: 1)  That each number has a value based upon the place it is in, and 2) how to line the numbers up correctly when adding.  You can see in the sample of student work that the place value chart is an excellent tool to help students with adding multi-digit numbers.
