This is a great printable activity to use at the beginning of the school year as a "get-to-know-you" activity. I love that it integrates math, works for a wide range of grade levels, and is fun and engaging for students. This printable should be used with 2"x 2" post-its.
I would use QR Codes in the classroom for a number of activities. Whether it was literacy, math, science or any subject, QR codes get students used to using technology in a fun and creative way. The student would grab a cube and complete each of the activities as part of a daily task. I would use this in my 1st grade classroom.
I like this saying because it encourages that mistakes are ok to make. I expect my students to show effort in the work that they do, and mistakes are fixable and acceptable as long as they keep trying. I would put this saying on a poster (on vinyl sticker like the one here) and keep in my classroom to remind students that it is ok to make mistakes.
Mathnopoly - Solving Equations. Based on Manoj Mistry (manojm03)'s excellent Mathonopoly idea, this is an adapted version I've made. The questions are designed for Year 7 students being introduced to solving equations. I've also created some humorous chance and community chest cards.
