Chunking Up Math: How Technology Can Simplify Complex Concepts for Students

Math can be a notoriously challenging subject for many students. Often, the difficulty doesn't lie solely in the concepts themselves, but in the sheer volume of information presented at once. This is where "chunking" comes in – breaking down large, complex ideas into smaller, more manageable units. And in today's classrooms, technology offers a powerful toolkit to help educators chunk math information effectively, making it more accessible and digestible for all learners.

The human brain has a limited working memory. When faced with too much new information at once, it can become overloaded, leading to frustration and disengagement. Chunking reduces this cognitive load, allowing students to process one concept thoroughly before moving on to the next. Technology can be instrumental in creating these well-defined, digestible chunks.

Today, we'll look at ways to chunk material using technology.  Begin by looking at interactive presentations and modules.  Gone are the days of static PowerPoint slides. Tools like Nearpod or Google Slides with interactive add-ons allow teachers to create presentations that break down complex math problems or concepts into sequential steps. Each slide can focus on a single "chunk" – a definition, a formula, or a specific step in a problem-solving process. Teachers can embed short videos explaining each chunk, pose quick formative assessment questions after each segment, or incorporate virtual manipulatives (more on those below) directly into the presentation. This guided, step-by-step approach ensures students master one idea before advancing.

Next, include virtual manipulative and simulations since abstract math concepts become much more tangible when students can interact with them. Virtual manipulatives, found on platforms like GeoGebra, Desmos, or even specific apps from The Math Learning Center, allow students to "chunk" abstract ideas into concrete actions. Want to teach fractions? Students can virtually divide pizzas or use fraction bars. Exploring geometry? They can build and manipulate 3D shapes. These tools allow students to focus on one aspect of a concept at a time, such as the relationship between numbers, the impact of changing a variable, or the properties of a shape, before synthesizing the larger idea.

You can also use short, focused video tutorials because often a live explanation isn't enough, or students need to revisit a concept multiple times. Creating or curating short video tutorials (3-5 minutes max) that explain specific math chunks is incredibly effective. A video might focus only on how to find the common denominator, or only on the distributive property. Platforms like Khan Academy are built on this chunking principle. Teachers can create their own videos using screen-recording software, explaining a single step or concept, and then assign them for pre-learning or review.

In addition, include adaptive learning platforms since  AI-powered adaptive learning platforms, such as Zearn or Prodigy, excel at chunking and personalizing learning. These platforms automatically adjust the difficulty and pacing based on a student's performance. If a student struggles with a particular concept, the platform will offer smaller, more scaffolded chunks of information and practice until mastery is achieved, before moving on to the next level. This individualized approach ensures no student is overwhelmed by information they aren't ready for.

Finally, use digital whiteboards can be used for step-by-step problem solving.  Tools like Google Jamboard or MathWhiteboard allow teachers to demonstrate problem-solving step-by-step, effectively "chunking" the solution process. Teachers can write out one step, explain it, and then add the next, allowing students to follow along without getting lost in a sea of numbers and symbols. Students can also use these boards to show their work in a chunked manner, making it easier for teachers to identify where misunderstandings occur.

By intentionally integrating technology into math instruction, educators can transform potentially overwhelming lessons into a series of manageable, digestible chunks. This not only aids comprehension and retention but also fosters a more positive and less intimidating learning experience for all students.  Let me know what you think, I'd love to hear.  Have a great day.

Chunking When Reading.

  Most of us when we were in school, never really learned to read a textbook.  The only thing I learned was to read the questions at the end of the section before reading so I could find the answer.  This technique does not work as well in mathematics.

What I learned later in life after leaving college and working for a few years were things I wished I'd known about then.  Over time, its become clear that chunking material, even in a textbook is important.

Too many of our students have a limited attention span and are not willing to read through the whole textbook.  If a student reads below grade level or is an English Language Learner, they find the assignment to be difficult but if we teach them to chunk the material, it can make it easier. In addition, these are things everyone should know.

Chunking by its nature, breaks the material down into smaller pieces so students are able to concentrate on one block at a time.  Here are a few suggestions to make chunking easier.

1.  Break the reading down into paragraphs or sentences.  Have the student read one section and then record the important point or points in a graphic organizer you prepare in advance.  At least until they've learned what information should go into the graphic organizer.

2. Before you have them paraphrase the text review specific decoding techniques so they have some tools at their hands.  I'd make copies of the text so they can write on the copy rather than the book. 
Techniques include, circling unfamiliar words, use context clues to determine their meaning before looking them up, replace the words with synonyms to make it easier to read, underline important information, read aloud, and read multiple times.

3. Begin by you deciding how the material should be chunked so as to provide modeling for the students.  Over time, have them do more and more so eventually they can do it on their own.

4. Take time to teach students how to paraphrase the text.  Many of my students think that writing it in their own words mean they should copy it but change one or two words.

5. Have students compare their paraphrased text to see similarities and differences.

Variations on the above activity:
1.  First step have students identify and define key words in their own words.
2. Create a visual with pictures or symbols.  Let them choose some visual that helps them remember.
3. To help students become proficient at paraphrasing, give them 10 words or less to summarize the material.
4. Ask them if they see connections to anything they've learned before so they call on prior learning.
5. Break the text into parts and use the jigsaw strategy to assign parts to different groups so they can share back the main information.

The idea behind chunking is that with the information broken into smaller pieces, the brain finds it easier to learn and remember it.
