This product is designed to be an exit ticket for lessons on doubles. Students would be completing as much of the worksheet as they can in one timed minute. This is a great way to assess for memorization of doubles facts! I usually use this worksheet after reviewing snap facts as a whole group, completing practice work and listening to a "doubles" song (there are many that can be found on youtube).
The worksheet is editable to change the order of the rows each day. It also has every other line highlighted which can be changed. The highlighting was used to assist a visually impaired student track her place on the worksheet.
