## Reflection: Connection to Prior Knowledge Estimate Lengths in Inches - Section 2: Model and Work Together

As I reviewed student work samples, I noticed that they had a hard time showing their work.  Make sure students understand what the problem is asking them to do.  I stopped the lesson to explain how to determine the answer to the given questions.

For example:

In problem one student were asked to find the total number of inches in rulers A and B.  I explained that they needed to use the first sheet and find the rulers labeled A and B and write the inches of the both rulers into the “show your work box”.  After that I ask students did they know how to determine the combine number of inches of both rulers.

Student response:

Add 6 and 1 together and you get 7.

Unit 5: Measure This Measure That!
Lesson 4 of 6

## Big Idea: Students will be able to estimate the lengths of objects by mentally partitioning the lengths into inches.
