Öğrenciler tamsayılar ve tamsayılarla işlemler yapma konusunda çeşitli öğrenme güçlükleri yaşamaktadırlar. Bu zorlukların üstesinden gelebilmek için alanyazında tamsayılar konusunun öğretiminde çeşitli bağlamların, yöntemlerin veya modellerin kullanılması tavsiye edilmektedir. Bu çalışmada tamsayılarla toplama, çıkarma, çarpma ve bölme işlemlerinin sayma pulları ve sayı doğrusu modelleri ile yapılışı açıklanmıştır. Tamsayılarla bölme işlemlerinin yapılışında sayı doğrusu kullanımının; negatif bir tamsayı ile pozitif bir tamsayının çarpılması ve pozitif bir tamsayının negatif bir tamsayıya bölünmesi işlemlerinde sayma pullarının kullanılmasının zor ve karmaşık olduğu görülmüştür. Bu sebeple tamsayılarla çarpma işlemlerinde kullanılabilecek “örüntü arama” ve bölme işlemlerinde kullanılabilecek “çarpma işlemi ile ilişkilendirme” stratejilerine yer verilmiştir. Çalışmanın tamsayılarla temel işlemlerin sayı doğrusu ve sayma pulları modelleriyle yapılışı hakkında öğrencilere ve matematik öğretmeni adaylarına önemli katkılar sağlayacağı düşünülmektedir.

Students have various learning difficulties in doing operations with integers and integers. In order to overcome these difficulties, it is recommended to use various contexts, methods or models in teaching the subject of integers in the literature. This study explains the use of counters and number line models when carrying out addition, subtraction, multiplication and division operations with integers. Some operations, such as multiplying a negative number with a positive number, and dividing a negative integer with a positive integer, were found to be difficult and complicated using counters and a number line, and so the strategies of “searching for a pattern” and “relating to multiplication” were included for use in integer multiplication and division operations, respectively. The present study is expected to support students and prospective mathematics teachers in the use of counters and number line models when carrying out basic operations with integers.
