I made a board builder activity on Discovery Education for phonic awareness. It's touches a lot of different sounds and how they are spelled. The english language is can be a little difficult to explain when it comes to phonic awareness and how they are spelled. I think the best way to learn is by repetition.
My learning activity needs a cube and several items. You should to get short worded items and you can get a dice by making one using a template, or just any dice will work.
First, you can make a cube or just labeling an already made cube beginning, middle, and end twice on the cube.
Then the box of items.
You let students roll the dice and if it lands on beginning, it means whatever item they pick out of the box they have to guess the beginning letters or letter.
Eg. I roll and it lands on "end."
I pick out a watch. I would say it ends with an "ch" because a ch makes a CH sound.
If the dice lands on beginning then you would say it begins with the letter "W" because it makes the "WH" sound.
You can repeat over and over again and have fun with it while learning. They eventually will learn more awareness on how to spell things and how to sound things out when writing.
