Virginia SOL 2.NS.1
Virginia SOL 2.NS.1 is part of the Number and Number Sense strand in Grade 2 Math (Math). Under this Standards of Learning objective, students utilize flexible counting strategies to determine and describe quantities up to 200, including skip counting and identifying even/odd numbers. Below is what 2.NS.1 covers in plain language, the specific skills it is assessed on, the key concepts to review, and how to practice 2.NS.1 for the Virginia SOL test.
What SOL 2.NS.1 means
Utilize flexible counting strategies to determine and describe quantities up to 200, including skip counting and identifying even/odd numbers.
Skills you’ll practice for 2.NS.1
- Represent forward counting patterns when counting by groups of 2 up to at least 50, starting at various multiples of 2 using tools like objects, number lines, or hundreds charts.
- Represent forward counting patterns when counting by groups of 5s, 10s, and 25s up to at least 200 using tools like objects, number lines, or hundreds charts.
- Describe and use patterns in skip counting by multiples of 2 (to at least 50), and multiples of 5, 10, and 25 (to at least 200) to justify the next number in the counting sequence.
- Represent forward counting patterns when counting by groups of 100 up to at least 1,000 starting at 0 using tools like objects, number lines, calculators, or one thousand charts.
- Represent backward counting patterns when counting by groups of 10 from 200 or less using tools like objects, number lines, calculators, or hundreds charts.
- Describe and use patterns in skip counting backwards by 10s (from at least 200) to justify the next number in the counting sequence.
- Choose a reasonable estimate up to 1,000 when given a contextual problem.
- Represent even numbers (up to 50) with concrete objects using two equal groups or two equal addends.
- Represent odd numbers (up to 50) with concrete objects using two equal groups with one leftover or two equal addends plus 1.
- Determine whether a number (up to 50) is even or odd using concrete objects and justify reasoning.
