Updated: Jan 6

This post explains and give practice opportunities related to TEKS 3.3D:

Instruction

This standard uses unit fractions (3.3C) to build and take apart fractions equal to or less than one.

Oral Language Development

Students process information through talking and conversing, not simply listening or watching a teacher demonstration. Here are some talk structures aligned with 3.3D to help you students unmute in the classroom.

You can find the Google Slide version here. You can also learn more about the Unmute model here.
