Grade 1 Math 

In this unit, students will build a strong foundation for understanding how addition and subtraction are connected. Students will identify number partners for 10, use models and equations to represent addition and subtraction situations, and solve problems within 10 using strategies such as counting on and counting back. Students will also use addition to help solve subtraction problems, generate related fact families, and represent real-world word problems with physical models, visual models, and equations. Through hands-on activities and real-world tasks, students will choose strategies, explain their thinking, and interpret data from class displays.

In this unit, students will strengthen their understanding of teen numbers and develop strategies for adding and subtracting within 20. Students will compose and decompose teen numbers as a ten and some ones, add three numbers using strategies such as making 10 and doubles facts, and use 10 as a benchmark to add and subtract. Students will also explore doubles and near doubles to build addition fluency. Through hands-on models, equations, number relationships, and real-world tasks, students will choose strategies, explain their thinking, and analyze data connected to problem-solving situations.

In this unit, students will strengthen their problem-solving skills by using models, equations, and strategies to solve addition and subtraction word problems within 20. Students will represent stories with known and missing values, use related equations to check their work, and solve comparison problems to find how many more or fewer. Students will also collect, organize, and compare data using tally charts and picture graphs. Through hands-on activities and real-world tasks, students will determine whether equations are true or false, find unknown numbers in equations, interpret data, and explain their mathematical thinking.

In this unit, students will build place value understanding by organizing, counting, reading, and writing numbers using tens and ones. Students will use concrete objects, visual models, and 120 charts to understand that two-digit numbers are made of groups of tens and ones. Students will count forward and backward, read and write numbers to 120, identify 10 more or 10 less than a number, and recognize patterns in the 120 chart. Students will also compare two-digit numbers using place value and symbols for greater than, less than, and equal to. Through hands-on activities and real-world tasks, students will analyze data, explain number relationships, and use math language to describe their thinking.

In this unit, students will strengthen their understanding of tens and ones while learning strategies for adding two-digit numbers. Students will describe numbers such as 10, 20, 30, and beyond as groups of ten, add and subtract multiples of 10, and add multiples of 10 to two-digit numbers. Students will also decompose numbers into tens and ones, add two-digit and one-digit numbers, and add two-digit numbers by combining tens with tens and ones with ones. Through hands-on models, equations, and real-world tasks, students will solve addition problems, explain their reasoning, compare two-digit numbers, and interpret data from class tally charts.
