Numerical Reasoning

Represent multi-digit numbers in a variety of ways to build place value understanding.

Read, write, and represent numbers to 100 using concrete models, drawings, standard form, base ten language, and equations in expanded form.

Represent and explain that whole numbers 1 through 99 are organized into groups of tens and ones, and a digit has a different value depending on its placement.

Compose and decompose whole numbers from 1 through 99 in more than one way using tens and ones. Explain and demonstrate each composition or decomposition with the use of concrete models, drawings, and/or equations.

Apply place value reasoning to identify the number that is one more and one less, ten more, and ten less than a given number with up to two digits.

Explain the relationship between numbers and quantities.

Count by ones forward or backward starting at any number up to 120 making accurate decade transitions.

Skip count by fives and tens from any multiple of five to 100, identifying place value patterns in the sequence.

Demonstrate the ability to compare quantities of objects and numerals representing quantities of objects.

Compare representations of two numbers up to 100 using the phrases is greater than, is less than, or is equal to (the same value as).
