Six ten-frames filled with red and yellow counters, the two colors used exactly the way they are in a classroom counter set. Under each frame is a blank sentence with three spaces, one for the reds, one for the yellows and one for the total. The splits vary, from 5 and 5 in a full frame down to 2 and 4 in a frame with four squares still empty, and no total goes past 10.
Writing the number sentence from a picture is the step that turns counting into addition, and the frames make the quantities easy to see at a glance rather than counting dot by dot. This one prints in color, so save it for the sheets you want to hand out rather than a full class set.
