My kids love to play hide and seek. I got this fun idea from the blog 1+1+1=1, it's somewhere on there...or one of her other blogs.....anyways, she gets the credit :)
Print out or use sets you already have, of the upper and lower case alphabet. Pick 1 room to hide the upper case letters in and one room to hide the lower case letters in, or rotate hiding them in the same room. Have your kids call out the names of the letters when they find them. They'll have fun yelling! You can really get creative with this idea and extend it to numbers and sight words as well. She had a list of suggestions. I wish I could find the post and share it. I encourage you to check out the blog and find it yourself, it's a fun place to explore.
