Number Talks - Subitizing Task Cards

In Algebraic Thinking Counting Mathematics Numbers

PDF | 10 pages|Grades: Pre-K - 2

Build number sense skills with this set of 30 subitizing 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. These exchanges will lead to the development of more accurate, efficient, and flexible strategies for students.

This teaching resource is designed to help your students with subitizing. The ability to subitize, or instantly recognize small arrangements of items, is a foundational skill for developing number sense.

Show students the front of the card briefly, giving them enough time to see the card without counting what is on it. Then lower the card out of sight, and ask the prompts on the back.

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.

CCSS.MATH.CONTENT.1.NBT.A.1
Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
In Grade 1 Standards for Mathematical Practice Number & Operations in Base Ten Extend the counting sequence
CCSS.MATH.CONTENT.1.OA.C.6
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - ...
