Give students additional practice with the tricky "c" and "k". Students must draw a picture card from the pile and then place it in the correct spot on the sorting mat. Is the missing letter a "c" or a "k"? Differentiate for students by allowing students to use the "c" and "k" rule poster also included in this file. You can make this file self checking by writing the correct answer on the back of each picture card. Great for vocabulary building too! Print on card stock and laminate for lasting durability. We hope this activity helps your students as much as it has helped ours! ENJOY!
