What is the Sequence in Math?


Children tend to follow a developmental sequence in their learning as they grow and develop. Children follow developmental learning progressions in their mathematical thinking, constructing meaning in their own way with foundational concepts and applying and extending them to more complex ideas at their own pace. So, is there a sequence to helping students develop mathematical thinking skills?

Some math skills must obviously develop sequentially. A student cannot begin to add numbers until he knows that those numbers represent quantities. Mathematics encompasses a wide variety of skills and concepts. Although these skills and concepts are related and often build on one another, it is possible to meet with success with some and have difficulty with others. For instance, a student may struggle with basic computation but finds he excels in geometry or with logic concepts. We can help our students develop a deeper and more comprehensive understanding of mathematics if we think of the subject in in terms of clusters of concepts and skills, rather than a strict linear progression.


As early as Nursery children begin to develop beliefs about what mathematics is and what it means to understand and to “do” math. Keeping students actively engaged, demonstrating enthusiasm, and using activities that encourage curiosity will help set a positive tone for learning math. In their first two years in a primary school class, students should develop a solid understanding of the number system, including place value. Students should begin to count aloud; recognize the number of objects in a group; follow a sequence of two- and three- step commands; understand relative size and sort objects by size and shape; perform addition and subtraction computations efficiently; and respond accurately to mathematical signs. Instruction should also encourage exploration and understanding of patterns and measurement concepts and begin to learn the concepts of time, money, and basic graphing.
