WASHINGTON GRADE 1 MATHEMATICS STANDARDS
Students continue to develop their understanding of whole numbers and how they relate to one another. Using that understanding, students start to develop critical place-value concepts of ones and tens.
Students learn about addition and subtraction, specifically, how to add and subtract, when to add and subtract, and how addition and subtraction relate to each other. Students continue to build a foundation for algebraic thinking by observing, extending, and creating a variety of patterns.
Students expand their knowledge of geometric figures by sorting, comparing, and contrasting them according to their common characteristics, and learn important mathematical vocabulary used to name them. Students work with shapes made out of basic two-dimensional figures.
Students begin to understand what it means to measure something and develop their measuring skills. They learn the difference between measuring length, weight, and capacity and use objects like toothpicks and craft sticks to measure length, marbles and a balance to measure weight, and cups filled with water or sand to measure capacity.
Data Analysis, Statistics, and Probability
Students are introduced to basic ideas of statistics by collecting and visually representing data. They reinforce their understanding of whole numbers and the operations of addition and subtraction as they ask and answer questions about the data.
Reasoning, Problem Solving, and Communications
Students further develop the concept that doing mathematics involves solving problems and discussing what they did to solve them. Problems in first grade emphasize addition, subtraction, and solidifying number concepts, and sometimes include precursors to multiplication. Students communicate by participating in mathematical discussions involving questions like, “How did you get that?”, “Why did you do that?”, and “How do you know that?” Students also learn to use mathematical language appropriate to their grade level.
