The learning of additive decomposition in kindergarten: A proposal for children from 5 to 6 years

Abstract

In this paper, I study the learning of additive decomposition in kindergarten through different types of situations. I begin with a review of the literature. Then I describe a proposal for the learning of additive decomposition based on three types of activities: a workshop on problem solving, an adaptation of the game of Tetris as a collective number game, and the use of interactive virtual five frames and ten frames. The aim was to record and analyze the strategies that children use to solve these kind of problems. In the results, we have seen that students mastered writing number sentences. The good previous level of students’ numerical competence has helped to the successful completion of decomposition problems.
