I found a fun Halloween freebie over at Teachers Pay Teachers today. It was created by Lil Country Kindergarten and you can get it for yourself by clicking here.
Since I teach second grade, I modified it a bit for my purposes. My students have been working on expanded form, so instead of having them color in numbers (which is perfectly appropriate for kindergarten), I made up a sheet that requires them to collapse numbers that are in expanded form to come up with the numbers that they need to color in. You can get it here for free. Thanks LilCountryKindergarten, and happy Halloween!
