Das KIRA-Buch: Kinder rechnen anders

Mathematics Through the Eyes of Children

Children calculate differently than one might expect. Fynn enters 2 hundreds, 4 tens, and 10 ones into a place value chart in an unconventional but correct manner, and then translates this representation into the numerical form 2410. Theo solves 64–37 by calculating 60 – 30, 4 – 7, and then 30 – 3 = 27. Selina subtracts 701 - 698 in writing and arrives at 1903 as a result. Even though Selina and Fynn do not arrive at the correct answer, they have done many things right. Theo's solution may appear incorrect, but it is actually correct.

The practical guide helps you understand these individual calculation methods and utilize them for support. Although the calculation methods of students do not always lead to correct results, they often stem from reasoning that makes sense from the children's perspective. For optimal support of the children, it is crucial that you engage with the thought processes of the learners and comprehend their calculation methods.

This book assists you in building that understanding through numerous examples. You will find typical calculation methods as well as frequently observed errors in the field of arithmetic; background information and practical tips for further work; methods for how you can assess the thought processes of children in everyday teaching. A guide for teachers, teacher trainees, students, and anyone who wants to understand and productively utilize children's mathematics.
