If your students love UNO they will love this similar style game.  A great addition to any explicit systematic phonics program. Games and playful activities are a great way for students to get multiple exposures of the sounds and alternative spellings of the alphabet code.
Set Two – the alphabet sound and alternative spellings
/or/ as in for
/oo/ as in book
/ow/ as in owl
/ie/ as in pie
/oo/ as in moon
Playful activities are a great way to reinforce learning and build skills.
These cards are also great for a word sort of alternative spellings.  Traditional games that have few rules such as snap, matching pairs and Go Fish are also great for multiple exposures of the sounds and spellings of the alphabet code.
