# Second Grade Math Curriculum -Standards, Lessons, Activities, Printable Worksheets

In second grade math, children need total mastery of their addition and subtraction facts since they are expected to do two-digit and three-digit addition and subtraction. If they don’t know these math facts instantaneously, their hesitation will make it hard to keep their pace in those second grade math problems. In second grade math, children start to learn fractions and need to get comfortable with the concept of a half, a third, a quarter, and an eighth. In geometry, second grade math students move beyond recognizing shapes to becoming fluent with the language of geometry so they can use terms such as ‘curves’, ‘vertices’, ‘edges’, ‘faces’ and ‘angles’ to describe the attributes of two and three-dimensional shapes.

### Second Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Number Sense and Operations

Second grade math includes use of ordinal numbers to 100th. The children will compare and order whole numbers to 1000. They will group objects into hundreds, tens and ones, relating the groupings to a written numeral.

Second grade math includes fractions. Students should understand halves, thirds, quarters, and eighths as parts of a set. They should know that a complete set makes one whole. The children will be skip-counting by 2s, 3s, 5s, 10s, 25s, 50s and 100s. They should learn to count forward or backward by 1s or 10s starting with any number less than 1000. They should also understand the difference between odd and even numbers.

Coins are used in teaching second grade math. The children will count mixed groups of coins including pennies, nickels, dimes, quarters, and half-dollars. They’ll be taught to recognize equivalent forms of money values, and should count coins up to one dollar or more during the course of the year.

During second grade, math students learn place values to 1000. They should be able to use place value patterns using 0 as a place holder (10, 100, etc.) and should understand that ten 10s equal 100. In numbers up to 1000, the children should know the place value of any designated digit.

By the end of the year second grade math students should recall addition and subtraction facts from memory. They should understand the inverse relationship between addition and subtraction, and be able to predict the relative size of solutions for both addition and subtraction – in other words they should understand that adding two whole numbers will result in a number larger than either of the two original numbers. Students should be able to add or subtract two-digit numbers with or without regrouping.

### Second Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Measurement

During second grade, math students should learn more about measurement and be able to communicate measurement concepts. They should understand both customary and metric systems of measurement and know when to use various units.

Second grade math students learn which units are most appropriate – such as inches or centimeters to measure something less than a foot long, or miles and kilometers to measure great distances. Besides measuring length, the children will learn to measure weight and capacity of objects. They will learn what tools are available for measuring linear dimensions, weight, capacity, and temperature.

Second grade math students learn to use clocks and calendars to measure time. They are taught the concepts of minutes, half-hours, hours, days, weeks, months, and years. The children should demonstrate an ability to use both digital and analog clocks to measure time including quarter-hours and five minute intervals. Using both Fahrenheit and Celsius thermometers, second grade math students learn to demonstrate an understanding of temperatures.

*Math Standards are defined by each state. Time4Learning bases its use of standards on the national bodies that recommend curriculum and standards and the interpretations of it by a sampling of states notably Florida, Texas, and California.

In second grade math, Sam learns about different units of measurement in the lesson Tipping the Scales.

In this lesson, students are asked to use a scale to compare the weight of a watermelon to a pile of apples.
