I utilized math journals last year with my first graders and would like to continue using them for the upcoming school year. I used them once a week and would have my students solve a challenging problem that focused on the current unit’s topic. Many of the problems had more than one answer or several possible answers, and students were responsible for showing and explaining their reasoning. I am looking for some new ideas and suggestions on how other teachers use math journals in the classroom. How often do you use math journals? What do you have them work on in their math journals? Do you have any resources, such as books or websites that you would recommend for ideas?
