Math Task Cards

Montessori children are great at math calculations! Our collection of math task cards support children in applying their mathematical knowledge to challenging tasks aligned to the Common Core State Standards. The cards cover standards across multiple grade levels, ordered by complexity and abstraction, thus honoring the spiral nature of the Montessori curriculum while meeting the requirements of the CCSS.
