Make your own custom dominoes using this Word document template. Simply use the "Replace All" feature in Word to replace the numbers with whatever you want (be sure to choose "fine whole words only" and if you need to know how to upload items other than text, email me and I'll send instructions). I made this because I wanted to make custom sight word dominoes for my kids. I couldn't find a template anywhere so I made my own and figured this may be worth putting on TPT.
This set goes up to double 6. I plan on offering a template that goes up to double 25 that I can customize for you (if you choose) for $2.
