Teachers can use these task cards during centers, independent practice, or small group instruction. These task cards can also be used as exit slips or small group activities where students work collaboratively to find a solution. Each NBT standard has 12 questions to provide some variety as well as an answer key. Also, the student recording sheet can be used for every standard in this package. To help with organization, each NBT standard is a different shade of blue to keep them all grouped together.
