### 1.1 Number & Operation

- 1.1.1 Count, compare and represent whole numbers up to 120, with an emphasis on groups of tens and ones.
- 1.1.1.1 Use place value to describe whole numbers between 10 and 100 in terms of tens and ones.
- 1.1.1.2 Read, write and represent whole numbers up to 120. Representations may include numerals, addition and subtraction, pictures, tally marks, number lines and manipulatives, such as bundles of sticks and base 10 blocks.
- 1.1.1.3 Count, with and without objects, forward and backward from any given number up to 120.
- 1.1.1.4 Find a number that is 10 more or 10 less than a given number.
- 1.1.1.5 Compare and order whole numbers up to 120.
- 1.1.1.6 Use words to describe the relative size of numbers.
- 1.1.1.7 Use counting and comparison skills to create and analyze bar graphs and tally charts.

- 1.1.2 Use a variety of models and strategies to solve addition and subtraction problems in real-world and mathematical contexts.
- 1.1.2.1 Use words, pictures, objects, length-based models (connecting cubes), numerals and number lines to model and solve addition and subtraction problems in part-part-total, adding to, taking away from and comparing situations.
- 1.1.2.2 Compose and decompose numbers up to 12 with an emphasis on making ten.
- 1.1.2.3 Recognize the relationship between counting and addition and subtraction. Skip count by 2s, 5s, and 10s.

### 1.2 Algebra

- 1.2.1 Recognize and create patterns; use rules to describe patterns.
- 1.2.1.1 Create simple patterns using objects, pictures, numbers and rules. Identify possible rules to complete or extend patterns. Patterns may be repeating, growing or shrinking. Calculators can be used to create and explore patterns.

- 1.2.2 Use number sentences involving addition and subtraction basic facts to represent and solve real-world and mathematical problems; create real-world situations corresponding to number sentences.
- 1.2.2.1 Represent real-world situations involving addition and subtraction basic facts, using objects and number sentences.
- 1.2.2.2 Determine if equations involving addition and subtraction are true.
- 1.2.2.3 Use number sense and models of addition and subtraction, such as objects and number lines, to identify the missing number in an equation such as: 2 + 4 = __; 3 + __ = 7; 5 = __ – 3.
- 1.2.2.4 Use addition or subtraction basic facts to represent a given problem situation using a number sentence.

### 1.3 Geometry & Measurement

- 1.3.1 Describe characteristics of basic shapes. Use basic shapes to compose and decompose other objects in various contexts.
- 1.3.1.1 Describe characteristics of two- and three-dimensional objects, such as triangles, squares, rectangles, circles, rectangular prisms, cylinders, cones and spheres.
- 1.3.1.2 Compose (combine) and decompose (take apart) two- and three-dimensional figures such as triangles, squares, rectangles, circles, rectangular prisms and cylinders.

- 1.3.2 Use basic concepts of measurement in real-world and mathematical situations involving length, time and money.
- 1.3.2.1 Measure the length of an object in terms of multiple copies of another object.
- 1.3.2.2 Tell time to the hour and half-hour.
- 1.3.2.3 Identify pennies, nickels and dimes and find the value of a group of these coins, up to one dollar.
