The big ideas and topics in First Grade are understanding and applying place value (number relationships), solving problems involving addition and subtraction (number operations), and composing and decomposing two-dimensional shapes and three-dimensional solids.

 

Students use relationships within the numeration system to understand the sequential order of the counting numbers and their relative magnitude.

 

Students extend their use of addition and subtraction beyond the actions of joining and separating to include comparing and combining. Students use properties of operations and the relationship between addition and subtraction to solve problems. By comparing a variety of solution strategies, students use efficient, accurate, and generalizable methods to perform operations.

 

Students use basic shapes and spatial reasoning to model objects in their environment and construct more complex shapes. Students are able to identify, name, and describe basic two-dimensional shapes and three-dimensional solids.
