### Overview

Math Grade 1 focuses on four critical areas. Students will develop an understanding of addition, subtraction, and strategies for addition and subtraction within 20. They will also develop an understanding of whole number relationships and place value, including grouping in tens and ones. Along with these important concepts, instruction will also include linear measurement, measuring lengths, and working with units of length. The final concepts taught connect the reasoning about geometric shapes, as well as, the composing and decomposing of shapes.

Math to the rescue! As students work through this course, they will use their math skills to help solve problems for Marv the Monster, Percy’s Pet Shop, and plenty more fun and silly characters and situations. Along the way, students will learn to solve word problems, skip count, and use math strategies to add and subtract. In addition, students will also “Rock the Clock” as they learn how to tell time.

Please view the Elementary Parents’ Survival Guide: The First Four Weeks of Online Learning for guidance on helping your student in the transition to online learning.

### Course Requirements

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.
