Mathematics Knowledge & Skills
Mathematics Knowledge and Skills refers to the conceptual understanding of numbers and their relationships, combinations, and operations. It also includes reasoning, measurement, classification, patterns, and shapes and their structure. Math skills during the early years help children to connect ideas and develop logical and abstract thinking. Young children learn to question, analyze, and understand the world around them.
Toolkit for Professional Development
Use the toolkit's Know, See, Do, and Improve sections to learn about and try best practices in math teaching at the early childhood level. Find tools to review and improve math teaching practices.
The materials in this toolkit are designed as professional development activities and resources. Head Start programs use a research-based curriculum. Some programs choose to add a supplemental curriculum with a focus on math. This kit can be used to enhance a quality curriculum that offers clear content, well-designed learning activities, and a research-supported scope and sequence.
