These cards help reinforce and align with the CCSS for listening and speaking! :)
I love using these cards with my students. My students were in the routine of turning and talking to their partner and asking the same weak questions during math core. I started using these discussion cards in my classroom and the level of understanding and comprehension shot through the roof! Students were able to explain and apply the strategies they were using to solve their math problems and justify their thinking. They also were much quicker to notice their errors when they had to respond in complete sentences to their partners inquiry. There are 16 different prompt cards to vary up questions and responses.
I did model these questions and proper responses many times through scaffolded lessons before this become solely a student task. Now during math time my students know to immediately get out their prompt cards with their other materials.
