Math Center: Number Sense Basics – Mixed Subtraction

Math Center: Number Sense Basics – Mixed Subtraction is a matching activity designed to build both a conceptual and working understanding that amounts can be represented in many ways.

The cards are specially designed so that students are required to mentally switch between different concepts as they endeavour to find a complete match. This requires a higher level of thinking than simply using the same visual representation.

These cards assist in developing mental computational fluency in young learners, creates flexibility in counting and is an ideal resource for independent math centers or math station rotations.

Instructions:

• Print, laminate and cut the individual cards.
• Mix/shuffle the cards.
• Using the imbedded arrows, students create a match of three by finding 2 cards that have the same value as the answer card.
• Cards can be divided into as few or as many sets as required.

This resource contains:

• 61 cards / 20 matches (3 cards to a match) and one title card.
• PDF and PNG files.

Enjoy!
