Kriah

Good morning! I continue to enjoy viewing and listening to your various topics. They are continuing to give me clarity on certain ideas, as I begin to work on curriculum development at my school here in Chicago.
I have a question: I noticed in your workshop about fluent kriah, that you gave some great activity ideas for practicing kriah, such as 1.dagesh ball game 2.switching a letter or a nekuda with cards or blocks, and 3.having the child read the new words that are formed, and dividing into teams to try to read one word at a time accurately, to gain cards for your team, etc.
Do you have practical ideas of activities that can be done for the next level up, like in a second grade classroom where the girls have already learned to read in kindergarten and first grade, and in second grade they are continuing to review all the rules again and get more practice to improve fluency? The teachers feel that continuing to practice over and over gets boring for the students, and they would love to hear a few new ideas to enhance the kriah in their classroom. What would your mehalach be in general for a mainstream classroom , to improve fluency?
Thank you in advance.
