Using a 100-Bead String

How to Use a 100-Bead String to Deepen Student Understanding of Whole Number Concepts, Place Value and Representing Word Problems

A 100-bead string is a concrete math tool used to represent a range of whole number big ideas and strategies. It has a built in structure of ten. Using this tool, students will also gain a deeper understanding of place value. 100-bead strings may be used to teach many of the 1st, 2nd and 3rd grade whole number standards including: comparing quantities, counting on past 100, adding and subtracting one and two digit numbers, rounding to the nearest ten, and multiplication using the distributive property by making “quick” arrays with several bead strings. Two bead strings can be used as a “concrete” tape diagram to represent word problems. AIS and Special Education teachers will find these tools useful.

Each participant will make twelve student 100-bead strings. Learn what makes this mathematical tool so powerful for the development of students’ mathematical understanding!

Audience: Grades 1, 2 and 3, AIS, and Special Education Teachers
