Nebraska Mathematics Standards Grade 2
MA 2.1 NUMBER: Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.2.1.1 Numeric Relationships: Students will demonstrate, represent, and show relationships among whole numbers within the base-ten number system.
MA 2.1.1.a Count within 1000, including skip-counting by 5s, 10s, and 100s starting at a variety of multiples of 5, 10 or 100.
MA 2.1.1.b Read and write numbers within the range of 0 – 1,000 using standard, word, and expanded forms.
MA 2.1.1.c Demonstrate that each digit of a three-digit number represents amounts of hundreds, tens and ones (e.g., 387 is 3 hundreds, 8 tens, 7 ones).
MA 2.1.1.d Demonstrate that 100 represents a group of ten tens.
MA 2.1.1.e Compare two three-digit numbers by using symbols and justify the comparison based on the meanings of the hundreds, tens, and ones.
MA 2.1.2 Operations: Students will demonstrate the meaning of addition and subtraction with whole numbers and compute accurately.
MA 2.1.2.a Fluently (i.e. automatic recall based on understanding) add and subtract within 20.
MA 2.1.2.b Add and subtract within 100 using strategies based on place value, including the standard algorithm, properties of operations, and/or the relationship between addition and subtraction.
MA 2.1.2.c Mentally add or subtract 10 or 100 to/from a given number 100-900.
MA 2.1.2.d Add up to three two-digit numbers using strategies based on place value and understanding of properties.
MA 2.1.2.e Add and subtract within 1000, using concrete models, drawings, and strategies, which reflect understanding of place value and properties of operations.
MA 2.1.2.f Use addition to find the total number of objects arranged in an array no larger than five rows and five columns and write an equation to express the total (e.g., 3 + 3 + 3 = 9).
MA 2.2.1 Algebraic Relationships: Students will demonstrate, represent, and show relationships with expressions and equations.
MA 2.2.1.a Identify a group of objects from 0-20 as even or odd by counting by 2’s or by showing even numbers as a sum of two equal parts
MA 2.3.1 Characteristics: Students will identify and describe geometric characteristics and create twoand three-dimensional shapes.
MA 2.3.1.a Recognize and draw shapes having a specific number of angles, faces, or other attributes, including triangles, quadrilaterals, pentagons, and hexagons.
MA 2.3.3 Measurement: Students will perform and compare measurements and apply formulas.
MA 2.3.3.a Solve real-world problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.
MA 2.3.3.b Identify and write time to five-minute intervals using analog and digital clocks and both a.m. and p.m
