Spiral Curriculum
Builds upon previously learned knowledge
Deepens understanding of topics
![Page 14: SPIRAL PROGRESSION in the K + 10 …...SPIRAL PROGRESSION in the K + 12 MATHEMATICS CURRICULUM Soledad A. Ulep University of the Philippines National Institute for Science and Mathematics](https://reader033.vdocument.in/reader033/viewer/2022041903/5e61f8ae2ca83d73624a63d3/html5/thumbnails/14.jpg)
Features
Learners revisit a topic.
The complexity of the topic increases with each revisit.
New knowledge being developed in each revisit has a
relationship with previously learned knowledge.
![Page 15: SPIRAL PROGRESSION in the K + 10 …...SPIRAL PROGRESSION in the K + 12 MATHEMATICS CURRICULUM Soledad A. Ulep University of the Philippines National Institute for Science and Mathematics](https://reader033.vdocument.in/reader033/viewer/2022041903/5e61f8ae2ca83d73624a63d3/html5/thumbnails/15.jpg)
Benefits
of Using Spiral Progression
It helps reinforce learning.
It allows a logical progression from simple to complex
ideas.
It encourages students to apply their previous learning to
later topics and new situations.
It helps learners appreciate the connections among the
different content strands.

Problem Solving
Problem solving should not only be
a goal of learning mathematics.
Problem solving should also be a
means of learning mathematics.
