Flash cards

I am having my students do word problems today and it became apparent that my students have issues with some of the vocabulary in terms of operations. 
I introduced students to the KFCW chart which is a math version of KWL.  They have to list what they know or information they are given.  F is used for the part of What do you want to find?  C is what do you need to consider?  This is where they write down what operation do they need to use? Is there some formula they will need to use?  How are you going to solve the problem?  Finally is W which stands for Work. This is where the student shows their work and the solution.  I showed it to the new Science teacher and she is making her students use the same form for science word problems.  I like the consistency between the two classes.
As my students are working the problems they get to the words telling them what operation to apply and they don't really know those words.  I have the SAS flash card app on their iPads, so I think beginning tomorrow, I will have students create flash cards for operation vocabulary so they can test themselves and learn the vocabulary.  I like the SAS flash card app because they can make either text based cards with the word, a picture, a voice over and the answer or an actual math problem. 
Yesterday, I managed to update the OS on all the ipads and downloaded a few different notebook type programs so I can use a different one in each period.  I am hoping that this will eliminate the issue of one student messing with another student's work.  I am hoping to begin the notebooks around mid October.
