DIY 'recipe' for Mod Podge ~ I have never used store brand Mod Podge, so I'm not sure what the consistency is supposed to be like, but when made per this, mine came out more watery than I was expecting. Still works though! Next time I will add less water.
link in with maths and geometry / shapes. paint different colours or use oil pastels (give students the task of shapes next to each other must have different colours) and put down masking tape, pull up the tape when finished. decorate by hanging around the classroom
