Grade 1 Mathematics


First Grade Overview

The big ideas for first grade students are focused on consolidating their counting knowledge, and exploring addition and subtraction as number operations. Working with number operations will draw heavily on the use of concrete materials and contextual situations that make sense to students. Measurement is introduced through time and money, and geometric ideas are based on students’ experience in the real world.
