Give the student a bingo dabber (bingo marker). He/she must dab the marker in the circles that are in the pictures.
NOTE: Students are not coloring with the bingo markers. They will just press down in the circle (just like you do when playing BINGO). They will try to stay within the lines of the circles.
I created worksheets with 2 different sizes of circles. As their fine motor skills improve, move on to the pictures with the smaller circles.
