I made this template to use as a student guide to make foldables. I use the worksheet with 3 boxes to help students fold papers into thirds, and the worksheet with 2 boxes to help fold in half.
I've used this worksheet as a template for myself in Word as I'm designing worksheets and foldables, as well as let the students use it for their foldables.
You will receive a 4 page Word file, so you may edit as you need for your classes. There are 2 pages (same) of 2 boxes, and 2 pages (same) of 3 boxes. On all the pages - the boxes fill up the page margin to margin.
