Using Models to Represent Tenths

In this MathUP video, Marian talks about the importance of using models to introduce fractions and decimals. She describes how teachers might use natural and abstract materials, including ten frames, fraction circles and rectangles, and number lines. Sh’s e also explains the benefits and challenges of using base ten blocks to introduce fractions and decimals.

Proportional and Non-Proportional Base Ten Materials
As students begin to work with larger numbers, we represent those numbers in increasingly abstract ways. In this MathUP video, Marian describes how we transition from proportional base ten materials to non-proportional materials. She explains the use of 10-frames, base ten blocks, and place value charts, as well as some common challenges students face when using more abstract, non-proportional materials. She also highlights the importance of working with students to prepare them for transitions to increasingly abstract representations of numbers.
