Subitizing
Example in 2nd Grade
About once a week we play subitizing games with rekenreks (math racks). I usually begin by displaying a virtual rekenrek on the SMART Board. I slide the white and red beads to create a number and show the arrangement very quickly! I ask my class what they saw? They often recognize the number right away, but sometimes they might have to combine smaller images together to determine the total number. Next I ask the students to form pairs and use the homemade rekenreks (made using laminated construction paper, pipe cleaners, and beads) to practice subitizing with a buddy.
