Work on precision with this coloring sheet is packed with words which focus on the different between the "ch" sound and "tr," so students say, "tree" instead of "chree."
I pass these worksheets out to my students, and as they master the sounds, they color the sheet.
Students at word, sentence repetition or sentence formulation will benefit from this coloring sheet.
Once they are finished with the page, they can take it home to hand up for generalization! :)
