Mathematics is often described as the science of patterns and structures. At the heart of the curriculum being developed on mrbeeteach.com lies a philosophy centered on coherence, deliberate representation choices, and small, structured steps to unveil the beauty of mathematical relationships. This blog delves into the unique approach of this curriculum in teaching addition and subtraction, highlighting its focus on helping students truly understand the structure of mathematics.
A Coherent Framework: Building Mathematical Connections
The curriculum is designed with coherence as its cornerstone. Each concept builds logically from the previous one, ensuring children grasp the interconnected nature of mathematics. By sequencing ideas in small, manageable steps, students develop confidence and a deep understanding. Instead of rushing through topics, this approach ensures learners can see the relationships between concepts, such as how addition and subtraction are inverse operations, or how number bonds underpin mental strategies.
This coherence is reflected in the PowerPoint slides and animations used within the curriculum, which carefully layer concepts. For example, animations demonstrate dynamic processes like regrouping or exchanging in a visually clear manner, reinforcing connections between abstract and concrete representations. These animations provide students with a clear sense of progression and help them visualise mathematical transformations.
Representations that Reveal Mathematical Structures
A deliberate feature of this curriculum is its consistent use of the same representations. By limiting the number of visual and concrete aids, the materials avoid overwhelming students and focus on those tools that best reveal mathematical structures. Examples include:
Ten-frames and counters to illustrate place value and composition of numbers.
Number lines for visualizing addition and subtraction as movements.
Part-whole models to highlight part-whole relationships and inverse operations.
These representations are used consistently to ensure students become familiar with them and can see their utility across different problems. By revisiting the same tools across topics, the curriculum emphasises the structure rather than superficial memorisation.
Small Steps: Precision in Teaching
Learning addition and subtraction is broken down into small, carefully considered steps. This approach minimizes cognitive load and ensures students master foundational skills before moving forward. For instance:
Recognising addition as combining two sets.
Understanding subtraction as finding the difference or taking away.
Using number bonds to build fluency in single-digit calculations.
Extending this understanding to multi-digit addition and subtraction through place value and regrouping.
At each step, the curriculum provides suggested activities to solidify learning. Activities highlighted with a yellow border encourage active engagement, offering students opportunities to practice and explore concepts through variation theory. By systematically varying the tasks, these activities help students notice essential patterns and relationships while avoiding surface-level repetition.
Stem Sentences: Supporting Mathematical Thinking
Language plays a pivotal role in mathematics. To help students articulate their understanding, the curriculum incorporates stem sentences. These structured sentences provide a scaffold for verbalising mathematical ideas, reinforcing conceptual understanding and precision.
By embedding stem sentences into activities and discussions, students develop the habit of explaining their reasoning, which deepens their comprehension and enables them to generalize their learning to new situations.
Activities Rooted in Variation Theory
Variation theory underpins the design of the curriculum’s activities, focusing students’ attention on critical features of a concept. Through carefully crafted examples and non-examples, learners are guided to notice key mathematical principles. For instance:
Varying the position of the unknown in addition problems (e.g., 3 + ? = 8 vs. ? + 3 = 8).
Exploring subtraction with different representations, such as "take away" versus "find the difference."
This approach encourages flexible thinking, helping students understand the underlying principles rather than relying on rote procedures.
