2nd Grade Math Course

Question 1: How can we use numbers, shapes, and data to understand and solve problems in the world around us? 

Question 2: What strategies can we use to break apart, build, compare, and organize numbers to make sense of math? 

Question 3: How can understanding how smaller parts make up larger wholes help us solve problems and understand the world around us? 

Question 4: In how many ways can we use numbers and shapes to represent the same amount or idea?

We learn to analyze data using bar graphs, then work with metric measurements and compare lengths. We also work with place value to express numbers in various forms. Money also helps us understand place value. We think flexibly about numbers as we read, write, and relate numbers in unit, standard, expanded, and word forms.  

We can use the skills to read data, measure different items and when working with $1, $10, $100 bills. Understanding place value helps us make sense of numbers as we prepare to add and subtract within 200. 

We learn strategies to make addition and subtraction easier. We use number bonds and number lines to understand how numbers work. 

We use our counting, addition, and subtraction skills when counting toys, snacks, stickers, animals, fruits, and more! When we add, we can find how many we have in all, how many more we need to reach a total, or what we started with. When we subtract, we can find what’s left, how much was taken away, or what we started with before something was taken away.  

We discover shapes like triangles, squares, and hexagons and what makes them special. Then, we build new shapes as we explore halves, thirds, and fourths. We also connect fractions to the clock when telling time. 

We can use this knowledge when cutting food and objects. We can tell the time to know when it’s time to go to school, recess, and when things are happening at home. 

We continue to add and subtract, but with numbers up to 1,000 now! We use mental math and drawings to make addition and subtraction easier. We also learn to make tens and hundreds, use compensation, and take from tens and hundreds. These tools help us solve word problems.  

We use these skills to work with larger amounts, like counting school supplies, toys, or groceries. Addition helps us find the total number of pencils in a classroom, figure out how many more markers we need, or what we started with before adding more. Subtraction helps us find out how many apples are left after snack time, how many crayons were used, or what we had before some items were taken away. 

We learn about the different coins and bills and how to count them. We also use our addition and subtraction skills from other modules in large quantities. We also learn to measure lengths using inches, feet, and yards. Then, we use number lines and line plots to organize measurement data. 

We can use our money skills at the store and when saving money. When we measure the length of a desk or the height of a plant, we use our measurement skills to find out how tall or long things are. Then, we can show and compare those measurements on number lines and line plots to better understand and share what we found. 

We learn about equal groups, how to make arrays, and how these arrangements help us count. Equal groups and arrays help us in third grade, when we learn about multiplication. We also learn about even and odd numbers and how they work when we add them together.  

We can use these skills when we’re arranging different items like boxes, books, and food. Arrays and equal groups will help us count quickly and recognize patterns. We use our knowledge of even and odd numbers when we’re grouping students into teams, setting up chairs in rows or sharing snacks to make sure everyone gets a fair amount.
