1. Data and Statistics · Represent and interpret data.
- Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables
- Picture & Bar Graphs: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories; solve put-together, take-apart, and compare problems using information presented in a bar graph
2. Geometry and Measurement · Work with time and money.
- Halves and quarters (age 7+): Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately
3. Geometry and Measurement · Relate addition and subtraction to length.
- Numbers on a number line: Represent whole numbers as lengths on a number line and represent sums and differences within 100 on a number line diagram
4. Geometry and Measurement · Measure and estimate lengths in standard units.
- Measuring with different units: Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen
- Comparing lengths by measuring: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit
5. Geometry and Measurement · Reason with shapes and their attributes.
- Decomposing a shape into more equal shares: Understand that decomposing a shape into more equal shares creates smaller shares
6. Relationships and Algebraic Thinking · Develop foundations for multiplication and division.
- Arrays for multiplication (age 7+): Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and 5 columns; write an equation to express the total as a sum of equal addends

- Place value understanding and number facts: Use place value understanding and number facts to solve problems
- Addition and subtraction within 1000: Add and subtract within 1000 using concrete models, drawings, and strategies based on place value; understand composing and decomposing tens and hundreds
9. Number Sense and Operations in Base Ten · Understand place value of three digit numbers.
- The three digits of a three-digit number: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones
- Comparing and ordering numbers: Compare and order two-digit numbers using the symbols >, =, and <, based on place value understanding
- Ordering Numbers to 1000: Compare and order numbers up to 1000 using >, =, and < symbols, based on place-value understanding
