Grade 1: Mathematics

Building Number Sense Through Concrete Experience

Mathematics Foundation

First grade mathematics builds a solid foundation in number sense through hands-on exploration with real objects. Students discover mathematical relationships by counting, grouping, measuring, and solving problems that connect to their daily experience.

Year-End Mathematics Goals

  • Count and write numbers 0-100 with understanding of quantity
  • Add and subtract within 20 using multiple strategies
  • Understand place value for tens and ones
  • Measure length using non-standard and standard units
  • Identify and describe basic 2D and 3D shapes
  • Tell time to the hour and half-hour
  • Count money using pennies, nickels, and dimes

Our Mathematics Philosophy

Concrete Before Abstract

Students manipulate real objects before working with numbers on paper. This builds genuine understanding rather than memorization.

Multiple Strategies

Children learn various ways to solve problems, developing flexibility and choosing methods that make sense to them.

Real-World Connections

Math problems come from children's experiences - counting toys, measuring their height, sharing snacks equally.

Number Sense Over Speed

We emphasize understanding quantity, relationships, and patterns rather than rushing to memorize facts.
