Elementary Math Grade 2
Open
The elementary math courses inspire students to become critical thinkers and problem solvers. The learners use math as a tool to make sense of and understand the world around them. The courses include media that uses sight and sound to engage students. For example, rhymes, chants, songs, and videos help teach and practice foundational math skills. Students explore content prior to being explicitly taught and hands-on activities help strengthen the learners’ algebraic and critical thinking skills. Students are provided with many practice opportunities that involve both on-screen and off-screen activities.
Please view the Elementary Parents Guide for Grades K-2 with guidance on helping your student transition to online learning and thrive at VLACS.

Course Materials
To achieve success, students are expected to submit work in each course weekly. Students can learn at their own pace; however, “any pace” still means that students must make progress in the course every week. To measure learning, students complete self-checks, practice lessons, multiple choice questions, projects, discussion-based assessments, and discussions. Students and families are expected to maintain regular contact with teachers because, when teachers, students, and parents work together, students are successful.
