The Common Core State Standards in Mathematics is really emphasizing number lines in student work with numbers.  So I thought I’d include one on a What Do You Notice? Poster at last night’s Family Math Night event.  But in order to reflect both the primary and intermediate grades, not only did I include the counting numbers, but I marked the fourths, as well.

Some students noticed the color pattern I used – even numbers are blue and odd are red.  Then the half was yellow and so on.  I also put a little dot to mark the halfway point between 0 and 5 and a lot of students picked up on that.  No-one converted fractions to decimals but my favorite comment was from Kelsey who noticed that “there are 20/4 in all on the graph”.
