Students completing grades K-5 in Weston all have Symphony Math accounts that were used throughout the year. Students can access their accounts through Classlink or symphonylearning.com
Teachers may have assigned content strategically to match the content of the grade. If your child enjoyed this platform, they are free to continue work in their account. They should choose "Courses" and choose the grade they just completed. They can then work through the rest of the material in a self-directed manner, rather than by teacher assignment. In most cases, we recommend against choosing material from the next grade. An alternative would be to choose the "Getting Ready For" courses or "Grade level Review". khanacademy.org
