Calculation Chains as Calculation Aids in Elementary School

Calculation chains have become a fixed component in elementary school, although they are still relatively unknown among parents. The calculation chain is ideal as a calculation aid or as a gift for first graders upon starting school. You can use a calculation chain to learn and practice various mathematical skills. Moreover, calculation chains do not require any prior mathematical knowledge. They are great for beginners or children with learning difficulties in mathematics, as they allow children to "grasp" math in the truest sense of the word.

In the TimeTEX teacher's shop, you can order calculation chains with 20 or 100 beads in red/blue or red/white at a reasonable price. They help children to familiarize themselves with numbers up to 20 or 100. They are suitable for first graders but can also be used as calculation aids in second grade up to fourth grade. Online, you can choose between sustainable calculation chains with beads made of ecological RE-Wood or beads made of plastic (RE-Plastic). The following will explain what calculation chains are exactly and how they work:

What are Calculation Chains?

A calculation chain, or calculation string, consists of 20 or 100 red and blue beads, strung on a tear-resistant cord in alternating groups of five. These help students recognize quantities simultaneously without counting the beads individually. The beads are specially designed to be comfortable for small beginners, making them easy to slide back and forth. The goal is for students to quickly and confidently calculate within the number range up to 20 and 100. The visual representation also promotes multisensory learning in children.

How do Calculation Chains Work?

Calculation chains work similarly to abacuses, also known as counting frames. However, the functionality is somewhat more modern, handy, and less complex. With the help of calculation chains in elementary school, children can independently or in partner/group work, with subsequent self-check, carry out almost all arithmetic operations visually, as they represent abstract numerical values. But how do you calculate with a calculation chain during math exercises?

When calculating with calculation chains, 5 or 10 beads of the same color are strung together. This plays a crucial role because kids can recognize at a glance, without counting, that it is a quantity of five. Students can easily slide the beads and thus perform arithmetic operations effortlessly. This way, tasks can be solved much faster.

What Children Can Train with the Calculation Chain

Recognizing quantities up to 5 & 10 simultaneously
Addition & subtraction up to 20 or 100
Multiplication & division up to 20 or 100
Comparing quantities up to 20 or 100
Breaking down numbers and quantities
Multisensory learning & abstract thinking
