- To Review with students on how to model a decimal number on the grid, we began by shading in .67 of our whole number.
- Because .67 almost fills up the entire grid, you only need .33 to fill the entire grid -- since .33 is less than .67 that means that .67 would round to 1 whole.
- We repeated this process for the last two problems on the grid sheet.

We expanded rounding into number lines. Number lines are the HARDEST to create, but the easiest to see with your eyes!

- To help the kids know how to build their number line, we look at what the question is asking.
- If the question says, round 4.7 to the nearest whole number - we know that our number line will START and END with whole numbers and have the next place value in the middle, in this case - tenths.
- Students should ALWAYS find the halfway mark and put a line through it. This creates a better visual for the rounding process.
- ===========================================================
- For the second number line, we were rounding to tenths, this means that we follow these steps:

- Circle the tenths place and put a line beside it. This tells me that my answer CANNOT go beyond this line. They are asking for tenths, so my answer must stop here.
- Underline the neighboring place value - which is hundredths
- Now I create the two ENDS of my number line - 1.6 and 1.7
- Think to myself - what is half way between 1.6 and 1.7. Once you discover the halfway point is 1.65 - mark it with a line.
- Fill in the rest of your number line.
