Number Talks – Decimal Representation Task Cards
Build number sense skills with this set of 28 task cards.
Use this set of task cards to easily implement number talks into your classroom.
Number talks are meant to be short, daily, math activities that allow students to have meaningful and highly engaging conversations about math. Simply show students the front of the card, and ask the prompts on the back. These exchanges will lead to the development of more accurate, efficient, and flexible strategies for students.
This card set is a great teaching resource designed to help students with:
- representing decimals in a variety of ways
- comparing decimals
- writing decimals in expanded notation
- relating decimals to fractions.
Print out the task cards front and back so that the prompts are displayed on the back of each card. The cards can also be put on a ring for added convenience.
