Our school uses the EVERYDAY MATH program published by McGraw Hill. The Everyday Math program aligns with the Common Core State Standards. Below is the Everyday Math online link for students and parents to access. Each student has an individual log-in and password that has been sent home to use. This is a valuable site that I encourage students to use. Students typically enjoy going to this site to play the interactive games that help build math skills. The Student Reference Book is a fantastic resource also available to our class online. The SRB helps explain skills and concepts taught in the classroom.
Below are some other educational game sites that are free to access and help strengthen math skills.
