Expectations & Examples of Numbers from the 2008 Math Standards Revision (draft) – Grade 1
Count by ones forward and backward starting at any number from 1 to at least 120, and count by twos, fives, and tens to at least 100. Start at 113. Count backward. I'll tell you when to stop. [Stop when the student has counted backward ten numbers.] Name the number before or after any number given verbally up to at least 120. Read aloud numerals from 0 to 1,000. Order objects or events using ordinal numbers.
Write, compare, and order numbers to at least 120 using the words equal to, greater than, less than, greatest, and least when appropriate.
Fluently compose and decompose numbers to at least 10.
Group numbers into tens and ones in more than one way and explain why the total remains the same.
Group and count objects by tens, fives, and twos.
Use words, objects, or pictures to show why a given whole number is odd or even. |
Expectations and Examples of Operations from the 2008 Math Standards Revision (draft) – Grade 1
Fluently compose and decompose numbers to at least 10.
Develop concepts of addition, subtraction, and equality (including commutativity and associativity of addition) using objects, pictures, and mathematical notation (+, -, =).
7 = 7 7 = 8 – 1 5 + 2 = 2 + 5 4 + 1 = 5 + 2 Develop facility with moving forward and backward on the number line to represent addition and subtraction.
Show the inverse relationship between addition and subtraction by using physical models, diagrams, and/or acting-out situations to undo an addition problem with subtraction and vice versa. Use the commutative and associative properties to solve a variety of addition and subtraction problems involving two or more one-digit numbers or symbols; justify the solution. 5 + 3 + 5 = ? 3 + 5 + 5 = ? 7 + ? = 9 Explain and use strategies for remembering basic addition facts for sums equal to at least 10, and related subtraction facts.
Quickly recall addition facts for sums equal to at least 10 and related subtraction facts. Create a story that matches an addition or subtraction expression or equation using objects, pictures, or words. Creating a story can be done orally, pictorially, or in writing.

Examples of Number Sense from the 2006 GLEs – Grade 1
Represent a number to at least 100 in different ways, including numerals, words, pictures, and physical models; and translate from one representation to another. Explain how to group and regroup objects into 1’s and 10’s. Show how to count sets of objects less than 100 using a variety of grouping strategies. Order three or more numbers to at least 100 from least to greatest. Express sequential relationships using comparative language, including equal to, less than, or more than, to order numbers to at least 100. Skip count by 2s, 5s, or 10s and explain or show the pattern. Count forward and backward from a given number that is less than 100. Express stories involving subtraction with words, pictures, and numbers. Show relationships between addition and subtraction using physical models, diagrams, and acting out situations. Apply strategies, including counting on, counting back, and doubling, for addition facts to at least 12. Use addition procedures in a given situation. Explain strategies or procedures used to determine sums. Use appropriate tools including mental math, paper and pencil, manipulatives, or calculator to add or subtract in a given situation. Use a known quantity to make reasonable estimates. Use numbers that are close to the given number and are easy to add or subtract to make a reasonable estimate of a sum or difference. |
