室外环境和新环境的培养对发展他们的算术能力都有帮助。 对于这种形式的课程开发，课程开发者和从业者有必要研究如何在花园或自然环境中培育数学经验。 为此，要满足两条基本原则。 首先，教育者必须明白，为了有效的数学教学，没有必要拥有特定的资源。 数学发展也必须有限的资源。 其次，在为孩子建立这样一个教学环境的时候，要保证环境的丰富，有利于统计可以组合在一起或者可以比较的类似因素。
Outdoor environment and new environment training would both be helpful for the child when developing their numeracy skills. For this form of a curriculum to develop, it is necessary for curriculum developers and practitioners to work on how mathematical experiences can be nurtured in the garden or natural environments. For this, two basic tenets are to be met. Primarily, the educator must understand that for effective teaching of mathematics, it was not necessary to have specific resources. Mathematical development must be possible with limited resources, too. Secondly, when setting up such a teaching environment for the child, it is necessary to ensure that the environment is rich with things which will facilitate counting similar elements that can be grouped together or could be compared etc.
