First you will need to download these cards here. I printed & laminated my cards so that we could use them for a while.
One of the most obvious tasks you can practice with your child is letter recognition and handwriting. Using a dry erase marker (or a pencil if you didn't laminate your cards) you can trace the letters. To practice phonics, you could give your child the card, and ask them, "Trace the letter that makes the _____ sound"
To practice number recognition for 0-20, you could point to the numbers for your child to identify. If your child is learning sight words you could just use these cards as flash cards for number words.
For an even more advanced task, you could give your child mini clothespins or wooden blocks, and get them to identify the number digit that corresponds with the number word. If your child is not quite there yet, or just learning sight words, I have provided a Matching Card in this set. Your child can hold the card and find the word that matches the one of the flash card, and then use a clothes pin (or other manipulative that you have) to identify the digit that matches the numerical word.
So, wow ok, I thought there were just 3 concepts at first, but since I've been writing this post, I realize that there are many more activities and uses with these cards:
letter recognition
handwriting
phonics
number recognition for 0-20
flash cards for number sight words
identification
matching
