This post specifically looks at how place value charts can be used to understand place value and compose/decompose numbers. Read more about TEKS Tools and their rationale here.
PlAce Value Charts
Place value charts, the third TEKS Tool, account for around 13% of each 3rd grade STAAR test. These charts help students understand our base-10 number system.
The main function of a place value chart is to show the relationship between place value locations in our number system. By visualizing numbers on a place value chart, students can compose, decompose, compare, and order numbers and understand place value magnitude.
Composing/Decomposing
Students deeply understand place value when they can rewrite numbers as the sum of smaller amounts based on various place value understandings.
3.2A - compose and decompose numbers up to 100,000 as a sum of so many ten thousands, so many thousands, so many hundreds, so many tens, and so many ones using objects, pictorial models, and numbers, including expanded notation as appropriate

2023-28: students were given a number to decompose in word form
2024-30: students were given a number to decompose in unit form
2025-1: students were given a number to decompose in standard form (twice)
2025-24: students were given a number in unit form to compose

Understanding Place Value Relationships
The magnitude of each place value, especially when the locations are not adjacent, can be visualized using a place value chart.
3.2B - describe the mathematical relationships found in the base-10 place value system through the hundred thousands place

2023-20: students were given representations for three quantities and asked to find the two that were equivalent
2024-4: students were given a number and asked to interpret the relationship between two of the digits
2025-27: students were given a number and asked to interpret the relationship between several of the digits
