Rekenrek
Rekenreks provide a tactile way for students to visualize and manipulate numbers, with 5 and 10 serving as key anchors. They help demonstrate how larger numbers, such as 7, can be broken down into parts, like 5 + 2. The 20-Bead Rekenrek is particularly useful for developing early strategies for addition and subtraction, laying the groundwork for a strong conceptual understanding and supporting the development of mental math skills.
