Elementary Math Content Standards

Second Grade Content Standards

Estimation

• Identify the number of objects in a set by counting or estimating.
• Decide whether estimation or counting is appropriate.

Number Sense

• Count by multiples of 2, 5, 10, 100.
• Understand basic place value concepts for whole numbers (ones, tens, hundreds).
• Fractions 1/2, 1/4, 1/3. Understand that fractions are parts of a whole. Be able to demonstrate an understanding of fractions physically or pictorially. Relate fractions to real world examples.
• Read and write numerals for simple fractions.
• Become familiar with the use of numbers in newspapers, magazines, television, and other sources within society.
• Acquire skills associated with values of coins and bills. This includes all appropriate vocabulary, the recognition of coins and bills up to $5, the knowledge of their value (coins in cents, bills in dollars), and the following equivalencies: one dime = 2 nickels; one quarter = 5 nickels; one half-dollar = 2 quarters; one dollar = 2 half-dollars, 4 quarters, or 10 dimes

Concepts of Number Operations

• Use objects, pictures, and problem situations to model and interpret different definitions of addition, subtraction, and multiplication of whole numbers.
• Write word problems representing different addition and subtraction situations and solve them.

Computation

• Accurately and with minimal hesitation provide response for basic addition and subtraction facts.
• Carry out a series of computations using a calculator involving addition and/or subtraction and involving up to four steps.

Geometry

• Relate physical world examples to the ideas and concepts of geometry.
• Identify and classify the following figures through visual observations and identified properties: triangles, squares, rectangles, cubes, spheres, circles, and ovals.
• Explore simple patterns of symmetry in the environment and the natural world.

Measurement

• Become familiar with attributes of length, weight, area, liquid capacity, time, and temperature.
• Acquire length and weight measurement skills: inch, foot, yard, meter, centimeter, ounce, pound, gram, kilogram; relative size of one unit to another.
• Use a ruler to draw a segment of a given length to nearest inch or centimeter.
• Acquire time measurement skills: calendar (days, weeks, months, years), equivalencies (one week = 7 days, one year = 12 months), clock (hours, minutes, fractional parts of hours), tell time to the nearest quarter-hour.

Statistics

• Construct graphs. State impressions obtained from these graphs. The data for these visual displays should come from realistic problem situations that occur in the classroom.
• Use simple charts for reference, comparisons, and record keeping.
• Become familiar with use of graphs in newspapers, magazines, television, and other sources within society.

Probability

• Explore the concepts of chance based on repeated observations of real world events such as weather, games, or contests.

Patterns

• Develop pattern recognition. This would be carried out primarily by working with simple sequences that are determined by numerical or geometric properties, or by other attributes such as color or orientation. The pattern may be represented physically, pictorially, or symbolically. The child should be able to describe the rule or relation that determines the sequence and continue the sequence.

Algebra

• Write number sentences to represent problems involving different addition and subtraction situations and solve the sentences.
• Use numbers to replace a box representing an unknown quantity in a number sentence (for example 9 + _ = 14) and determine if the replacement makes the sentence true.
