### NR Numerical Reasoning

- Counting, numbers, equality, place value, addition, subtraction
- 1.NR.1 Extend the count sequence to 120. Read, write, and represent numerical values to 120 and compare numerical values to 100.
- 1.NR.1.1 Count within 120, forward and backward, starting at any number. In this range, read and write numerals and represent a number of objects with a written numeral.
- 1.NR.1.2 Explain that the two digits of a 2-digit number represent the amounts of tens and ones.
- 1.NR.1.3 Compare and order whole numbers up to 100 using concrete models, drawings, and the symbols >, =, and <.

- 1.NR.2 Explain the relationship between addition and subtraction and apply the properties of operations to solve real-life addition and subtraction problems within 20.
- 1.NR.2.1 Use a variety of strategies to solve addition and subtraction problems within 20.
- 1.NR.2.2 Use pictures, drawings, and equations to develop strategies for addition and subtraction within 20 by exploring strings of related problems.
- 1.NR.2.3 Recognize the inverse relationship between subtraction and addition within 20 and use this inverse relationship to solve authentic problems.
- 1.NR.2.4 Fluently add and subtract within 10 using a variety of strategies.
- 1.NR.2.5 Use the meaning of the equal sign to determine whether equations involving addition and subtraction are true or false.

- Base ten structure, addition and subtraction within 100
- 1.NR.5 Use concrete models, the base ten structure, and properties of operations to add and subtract within 100.
- 1.NR.5.1 Use a variety of strategies to solve applicable, mathematical addition and subtraction problems with one- and two-digit whole numbers.
- 1.NR.5.2 Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
- 1.NR.5.3 Add and subtract multiples of 10 within 100.

- 1.NR.5 Use concrete models, the base ten structure, and properties of operations to add and subtract within 100.
