# Grade 1 Overview

• As in kindergarten, first graders continue to have mathematical conversations as a part of rug time through routines such as tracking the date on the calendar, graphing the weather, and counting the days in school.  They also explore mathematical concepts through play during choice time through activities such as block building, drawing, and playing games.

First graders also have a more formal math time in the schedule of the day.  This time includes whole group, small group, and individual exploration of the main content of first grade math. Children discuss mathematical ideas as part of large and small groups. They play games to reinforce and practice skills in fun and motivating ways.  They complete written work and puzzles, such as Marcy Cook tiles and Winnetka Math Books, to connect ideas to their written representations.

The main ideas in first grade are

• Addition and subtraction of totals less than 20 in number stories and rote computation. First graders become fluent with facts within ten.
• Exploring the place value of larger numbers through concrete models (blocks or pictures). This lays the foundation for work in second grade adding and subtraciton two-digit numbers.
• Understanding equality, such as 3 + 2 = 5 and 5 = 3 + 2 and 3 + 2 = 1 + 4. This is foundational work for algebraic reasoning.
