Children love Halloween, so it's a great time to use motivating dot to dots to support skip counting and alphabetizing.
Skip counting is an important skill for teaching functional math skills. Students need to be able to count by ten's in order to count dimes, and count by 5's in order to count nickels. Both skills are essential for counting money, mixed quarters, dimes, nickels and pennies (assuming they have strong counting skills.) Children on the autism spectrum often need to memorize, and these worksheets offer lots of practice. Children with auditory disabilities also benefit from doing visual practice using dot to dots.
Holiday themed worksheets of this sort also help overcome the "age appropriate" challenge faced by teachers trying to overcome the accusation of giving young teens "baby work." Because Halloween is a fun time for all students, even (or should I say especially) older students, these worksheets qualify.
There are four pictures: a ghost, a witch, a jack-o-lantern, and a haunted house. Each appears both as a skip counting and an alphabetizing worksheet.
