Our younger students learn about parallel lines in different grade levels in different states. But there is some key content that students need to know related to parallel lines. This content card provides key content. (If you see other things that need to be added, please leave a comment and I’ll update this. *All of my content cards are a work in progress*.) DOWNLOAD THE CONTENT CARD FOR PARALLEL. I’ve included a piece that is not in most elementary programs – and that is how to write a math sentence that shows two lines are parallel.

Remember that in curriculum development world, we still need to work on things students must be able to do with this content at the elementary school level. Do we want students to identify parallel lines in everyday things? Do we want students to distinguish between a parallel line and a perpendicular line? What about explaining what a parallel line is? What about explaining why a line that is not parallel *isn’t*? Do we want students to explain the difference between parallel lines and intersecting lines? These kinds of things become objectives in your curriculum.

For those of you in charge of developing curriculum, there are a couple of questions you’ll want to answer: What core content do you want at each grade level in relation to this concept? What do you want students to do with the content at each grade level? By the way, content cards are a good way to check vertical and horizontal alignment in a curriculum at the district level.

If your role is that of designing assessments, the content cards are a big plus as well. When everyone works from the same core content – and the same objectives, you support tight alignment at the classroom level – which is where alignment really happens.
