Mathematics in Grade 2
Grade 2 students learn more about whole numbers and how they work together. As they understand more about arithmetic operations (such as addition and subtraction), children find more flexible ways of thinking about problems and how to solve them.
During second grade, students learn place values and number relationships when adding and subtracting. Students also discover new ways to think about numbers. They begin to work with fractions and decimals. They measure quantities in appropriate units, such as inches or feet. They identify and classify shapes such as circles and triangles.
TOPICS COVERED
Expectations for what a child should be able to do increase from one grade to the next. They include:
• Understanding numbers and how they work, such as adding, subtracting, multiplying, and dividing (Number Sense and Operations)
• Investigating patterns and using symbols (such as x + y = z) to analyze mathematical situations and change (Patterns, Relations, and Algebra)
• Identifying shapes, sizes, and relationships (Geometry)
• Using number relationships to find out size and volume (Measurement)
• Doing experiments, collecting data, and using the information to decide what will happen (Data Analysis, Statistics, and Probability)
WHAT YOUR CHILD SHOULD KNOW
BY THE END OF GRADE 2, YOUR CHILD SHOULD KNOW AND BE ABLE TO PERFORM THESE SKILLS:
1. Count, read, and write whole numbers such as 1, 3, 7, and 287 — up to 1,000. Relate whole numbers to the quantities they represent.
2. Compare numbers to 1,000 and put them in their correct order. Use the symbols > (greater than), < (less than), and = (equal to).
3. Show that addition is the inverse of subtraction (for example, 3 + 5 = 8 and 8 – 5 = 3). Use this understanding to simplify calculation and check their solutions.
4. Add and subtract three-digit numbers accurately and efficiently. For example, 563 – 231 = ?
5. Represent multiplication as repeated addition. For example, 5 x 3 is the same as 5 + 5 + 5.
6. Identify and write commonly used fractions such as 1/4 or 2/3.
7. Classify familiar two- and three-dimensional shapes by common characteristics. For example, how many corners does a triangle have?
8. Measure and compare the length of common objects using metric units to the nearest centimeter and U.S. customary units to the nearest inch.
HOME ACTIVITIES
1. Use a clock to help your child think about adding and subtracting. Ask your child what time it will be in three hours or what time it was two hours ago.
2. Together, find ways you use math in daily life. For instance, you use fractions to slice a pizza for the number of people eating it.
With your child, explore your home to find different geometric shapes, such as circles or triangles.
Measure your child’s height and mark it on a wall. Let your child help measure and mark the heights of some toys. Together, compare the different heights.
Explore time, money, number sense, geometry on the Internet with your child.
