 ### First Grade Math

The first grade math curriculum is “Investigations in Number, Data, and Space”, which was developed by TERC (Technical Education Research Center here in Cambridge). The curriculum is designed to help children develop number sense and basic skills through hands-on activities. Problem solving and thinking mathematically are an important focus of the curriculum. Children spend time exploring problems in depth, and are encouraged to invent their own strategies and approaches, rather than rely on memorized procedures. Students are encouraged to express their mathematical thinking through drawing, writing, and talking while working in a variety of groupings: whole class, individually, pairs, and small groups.

The units are:

• How many of each?: Addition, Subtraction, and The Number System
• Making Shapes and Designing Quilts: 2-D Geometry
• Solving Story Problems: Addition, Subtraction, and The Number System
• What Would You Rather Be?: Data Analysis
• Fish Lengths and Animal Jumps: Measurement
• Number Games and Crayon Puzzles: Addition, Subtraction, and The Number System
• Color, Shape, and Number Patterns: Patterns and Functions
• Twos, Fives, and Tens: Addition, Subtraction, and The Number System
