Base-ten materials and decimal squares are highly effective for teaching place value because they provide a concrete representation of the hierarchical structure of numbers. Base-ten materials, such as base-ten blocks or rods, visually demonstrate how numbers are composed of units, tens, hundreds, and so on. By using these manipulatives, students can physically build numbers and see how different digits represent different values based on their position in the number.

Decimal squares complement this understanding by allowing students to explore decimal place values in a similar way. They highlight the importance of the decimal system and show how values get smaller as the place value moves to the right. This hands-on approach helps students grasp the concept of place value intuitively, as they can manipulate the materials to see the relationships between different values clearly.

In contrast, the other options may not specifically emphasize place value. For instance, pattern blocks and tangrams are better suited for teaching geometry rather than numerical concepts, while geoboards and fraction circles focus more on spatial relationships and fractions. Money and spinners can introduce some mathematical concepts, but they don't provide the same direct connection to understanding the place value structure.
