Math

• The Third-grade child has learned how to represent numbers using expanded form with the base ten system.

For continued development, encourage the child to explore different manipulatives such as base ten blocks or place value disks. These hands-on materials can help reinforce their understanding of expanded form and provide a concrete representation of numbers. Additionally, you can create games or activities where the child needs to identify the expanded form of a given number, or vice versa, to make the learning experience more engaging and interactive.
