I use this product frequently in stations, as lesson application or for early finishers. Sometimes I use it for test prep. My students always love the color squares because they get to color. I love this product because they are practicing standards. The color visual is also very easy to grade!
I give the students the worksheet. In the directions it tells the students what colors to use. (However you know there is always that student that hates the color choices, so I always let them choose the colors they want, but they must create a legend for me.) Students will use one color for facts and one color for opinions, it’s as simple as that.
