In first grade, math begins to get a little more advanced. Students will build upon what they learned in kindergarten and they will learn to use their math skills in different ways. In the most basic sense, first grade math involves building number sense. Number sense is having a basic understanding of numbers, what they are, and how we use them. Students will count, skip count by twos, fives, and tens, write numbers in word form, and add and subtract. They’ll learn to take the next step, like adding three single digits together. In algebra, students will study the rules of operations and gain a better understanding of what symbols represent in number sentences. In the area of data, students will learn to collect, organize, and analyze information. Students will also learn some basics about probability. They’ll be asked to compare data and use vocabulary like likely and impossible. In geometry, they’ll study shapes and objects by doing things like counting sides and vertices and learning how to flip and slide shapes. When it comes to measurement, they’ll use both standard and non-standard units of measurement. They’ll be asked to estimate and compare, using math vocabulary like more than and less than.
