***Please note that for some of the number line that involve sliding numbers into a position, you will need to do this in edit mode or Fullscreen interactive Google Slides. This is for only a few slides. The rest may be presented as normal.

This is made to supplement Unit 4 of Bridges 3 new curriculum. These are interactive slides meant to aide in the instruction of each session. This is not to be used as an independent lesson. This is only to help reduce the time in preparing for your lessons each day. They are meant to be used along with the teachers manual and provided materials.

It is necessary to use in conjunction with the Bridges manual as they provide the structure, the models, and thinking that is necessary for mastery of first grade skills.
