State and Model the Objective
Tell the children that they will go on a treasure hunt where X marks the spot as they listen for words that end with the /ks/ sound, such as fox, box, six, and wax.

Literacy Activity
X leads to the treasure box 

• Hide the picture cards and the treasure box (with the "treasure" or treats inside it) around the room. 
• Tell the children that they need to look for picture cards that end with the /ks/ sound. 
• When a picture card is found, have the child say, “I found a(n) ___, and it ends with /ks/,” and have everyone say together, “___ ends with /ks/!” 
• When all the /ks/ pictures have been found, have the children search for the X that marks the spot and the box. 
• Have the children say the /ks/ sound three times to open the box. 
• Open the treasure box and share the treasure or treat inside.
• Help the children recall words they heard in the lesson that end in /ks/ and emphasize the /ks/ sound as you all say them together. 

More Practice
Repeat the name of the target letter 

• Play "Hot Potato" with the large uppercase letter X (see below). 
• Set a timer for 30 seconds. 
• Sit in a circle and pass the X around quickly. 
• When the timer goes off, have the child who is left holding the X say, “X makes the /ks/ sound and X marks the spot!”
