This is one of my kiddos top favorite activity to do.
Here's why-
1.  Stickers what child doesn't like stickers 
and
2. It's like going on a egg hunt.

Materials

• Letter Snowflakes
• Color Dot Stickers
• Painters Tape

Directions

• Type the letters on the editable sheet that you want to review with the children after returning from winter break.  I only put the letters that we introduced from August to December. 
• Write the letters on dot stickers.
• Providing each child with a strip or two of letter stickers.  
• Hide the letter snowflakes around the room.  Children take their letter dot stickers and move around the room finding the corresponding letter to stick their dot sticker on.

Keep your snowflakes up because they will want to play again.  

This is a fun way to get kids recognizing and forming letters.
