Assessing understanding during hands-on maths activities doesn’t require stopping the lesson or putting students on the spot. By observing carefully, asking targeted questions, keeping brief notes, collecting work samples, and using exit tickets, teachers can quickly identify who understands, who needs support, and who is ready for a challenge, all while keeping the energy in the room alive.

Right now, as a teacher, you probably know the feeling: your students are busy moving counters, building shapes, or using bead strings, and while they look engaged, it’s hard to tell who’s actually learning. You want to make sure everyone is progressing, not just staying busy. The good news is you can find out what they understand without slowing down the lesson or putting certain students on the spot.

In this post, we’ll look at simple, practical ways to check understanding while keeping students engaged and having fun.

The Challenge of Assessment in the Concrete Learning Phase

When students are using hands-on tools, it’s not always easy to tell who really understands what’s happening. Just because a student can move the blocks correctly doesn’t mean they grasp why it works that way.

For example, a child might split 12 counters into two equal groups correctly but may not truly understand what division is. This is the “hands-on” phase of learning, where students are exploring ideas physically before fully internalising them.

The key is to watch and listen as they work, so you can step in and offer support the moment someone needs it.

Observation Strategies: The “Look For” During Activity Time

Watching students carefully is one of the easiest and most effective ways to see who understands and who might need help. Here’s what to keep an eye on:

  • Following steps: Are they just guessing, or are they thinking through the process?
  • Using strategies: Are they grouping objects, counting in patterns, or spotting shortcuts?
  • Noticing mistakes: Do they spot and fix errors on their own?
  • Talking with peers: Are they explaining what they’re doing or asking for help in a purposeful way?

For instance, with bead strings, you might notice one student quickly recognises 7 + 5 as 10 + 2, while another is still counting one by one. These differences tell you exactly where to step in with support.

The Power of Questioning: Prompting Conceptual Disclosure

Watching shows you what students are doing, but asking questions reveals why. Encourage students to explain their thinking with simple prompts:

  • “How did you know that’s the answer?”
  • “What did you notice when you moved the counters?”
  • “Can you show me another way to solve it?”
  • “What did you do first?”

Even a simple question like “What did you do first?” can reveal whether they truly understand or are just following steps without connecting the ideas.

Getting students to talk about their thinking not only helps you assess, it also strengthens their understanding. Having them explain to peers gives you even more insight and helps build their confidence at the same time.

Using Checklists and Anecdotal Records for Quick Data Collection

Sometimes you need to capture what’s happening in the classroom quickly without stopping the flow. This is where simple checklists or short notes are really useful.

Checklists: Create a brief list of the skills or steps you want to see. As students work, tick off what they do correctly. For example, in a counting activity, you might look for:

  • Did they group items correctly?
  • Did they count accurately?
  • Did they show or explain their answer clearly?

Quick notes: Jot down short observations about strategies students are using or misconceptions you notice. For example: “used groups of 5” or “needed help counting back.” These notes don’t need to be elaborate. Just a few words can jog your memory and guide your next lesson or a 1-to-1 session. Over time, they build a clear picture of where each student is and what they need next.

Collecting Tangible Evidence: Work Samples and Photos

Sometimes it’s helpful to capture evidence you can look at after the lesson. Work samples and photos let you review how students approached a problem when the moment has passed.

  • Snap a photo of a student’s bead string setup to check how they split numbers.
  • Keep a copy of a student’s pattern activity to analyse their thinking later.

These snapshots are useful for tracking progress over time. You can see growth from “just counting” to “thinking strategically” and use the evidence to inform future lessons and progress reports. This kind of documentation works well alongside the maths training resources we offer for teachers looking to sharpen their formative assessment practice.

Leveraging Exit Tickets and Reflective Journals for Abstract Assessment

As students grow more confident with hands-on activities, you want to see whether they can explain their thinking without the physical tools. Exit tickets and reflective journals make this easy:

  • Exit tickets: One short question at the end of the lesson, like “Write one way to make 10 using counters,” gives you a quick and clear picture of who’s got it.
  • Reflection journals: Encourage students to jot down strategies, difficulties, and successes. Simple prompts like “What helped you today?” or “What was tricky?” gets them thinking about how they solved problems, not just what the answer was.

These tools encourage students to reflect on their learning while giving you concrete evidence of who understands the concept and who needs more time.

Assessing understanding during hands-on maths doesn’t need to be complicated. By watching students, asking simple questions, jotting quick notes, and collecting examples of their work, you can see who’s got it, who needs a hand, and who’s ready for a challenge, all while keeping the lesson flowing smoothly.

Students become more confident and reflective when they know you’re noticing both what they do and how they think, and they start taking more ownership of their learning as a result.
