What to use to supplement / reinforce OPG?

[Paula in PA]

My dd is near finishing OPG and we have run into problems in the last 4 lessons. She is having problems using the skills we've covered to sound out the multisyllable words. She has also been doing a lot of guessing during her other reading, instead of sounding out the word, and usually gets it wrong. I've looked at both ETC and All About Spelling and wonder if either of those would help to reinforce what she's learned in OPG while using a different method from it. Or is there something else that might work?

I use Phonics Pathways to reinforce OPGTR.
