Number Lines

The girls have been working with number lines for the past two days and are becoming much more comfortable using them as another tool to help them solve addition problems.  Today the girls rotated around the room in centers, each center using a number line in a different way.

Center 1:  The girls worked on the Mystery Number app on their iPad.

Center 2:  The girls had to create their own number line by cutting and sequencing numbers.

Center 3:  The girls pulled addition problems from a bucket, wrote the addition sentence on their paper and solved the problem using number lines.
