In Math Grade 1, students will use strategies to solve word problems, skip count, and use math strategies to add and subtract. The course provides the opportunity for students to develop an understanding of place value using tens and ones. Students will use this knowledge to add and subtract within 100. Defining and non-defining attributes of shapes is another focus of the course. Other engaging hands-on activities include money, time, data, and measurement.

### 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.
