Bead strings are simple, hands-on tools that build early number sense in primary students. By using them to teach subitising, the jump strategy for addition, and part-part-whole thinking for subtraction, teachers can help students move from counting one by one to confident mental maths. The goal is to gradually phase out the beads as students internalise the strategies.

Right now, as a teacher, you’ve probably seen some students count quickly but struggle to think about numbers flexibly, while others get stuck on addition and subtraction altogether. Bead strings can help. They’re simple, hands-on, and great for building early number sense.

In this post, we’ll share practical tips for using bead strings, from basic counting all the way through to building mental maths skills.

Introducing the Bead String: A Powerful Tool for Early Number Sense

Bead strings are exactly what they sound like: a string of beads, usually grouped in sets of 5 or 10, and sometimes colour-coded to support visualisation.

Here’s why they work so well:

  • Students can see and touch the beads, which links counting to physical experience.
  • Students start recognising small quantities instantly without counting every single bead.
  • The groupings make it easier to understand numbers in chunks, which is key for addition and subtraction.

For example, a string of 10 beads with 2 red beads, 3 blue beads, and 5 yellow beads helps students see numbers as parts of 10. They don’t just see the number 10, they see “2 and 3 and 5,” which is a significant step toward flexible thinking.

Teacher Tip 1: Bridging the Count-All Strategy to Subitising

Many students start addition by counting every bead one by one. This “count-all” strategy works, but it’s slow. Bead strings help bridge this to subitising, meaning pupils learn to recognise groups without counting each bead individually.

How to do it:

  • Show a small set of beads, like 4 or 5. Ask students “How many do you see?” Let them count first, then point out that some students can see 4 straight away.
  • Gradually increase the number of beads and encourage students to spot groups of 2, 5, or 10 instead of counting them all.
  • Highlight patterns on the string. For example: “There are 5 red beads here, and 3 blue beads, and that equals 8 in total.”

This helps students move from slow counting to seeing numbers in chunks, a crucial step toward faster, more confident addition and subtraction.

Teacher Tip 2: Using the “Jump” Strategy with Bead Strings (Addition)

The jump strategy is a great way to teach addition on bead strings. Instead of counting every bead, students “jump” along the string in chunks.

Example:

  • To solve 7 + 5, students start at 7 on the bead string.
  • They make a “jump” of 3 to reach 10.
  • Then they jump the remaining 2 to reach 12.

This approach does several things at once:

  • It highlights the friendly number 10: Bead strings often group beads in tens, making 10 easy to spot without counting each bead. As 10 is so fundamental in maths, this sets students up for more advanced problems like place value and multiplication.
  • It strengthens understanding of number relationships: Students can see that 7 is made of 5 + 2, or that 10 minus 3 leaves 7. Numbers stop being standalone digits and start being made up of parts.
  • It builds a foundation for mental strategies: When students know how groups of 10 combine, they start adding in their heads. For example, “8 + 2 makes 10, plus 3 more makes 13” instead of counting each bead. Bead strings make these mental strategies accessible when students are ready for them.

Encourage students to say out loud what they are doing: “7 plus 3 makes 10, plus 2 more makes 12.” Talking through it reinforces understanding and lets you hear their thinking in real time.

Teacher Tip 3: Exploring Part-Part-Whole Concepts (Subtraction)

Bead strings aren’t just for addition, they’re also great for teaching subtraction and helping students see how numbers can be split into parts.

How to use them:

  • Start with a full string of beads, for example 10.
  • Ask “If we have 10 beads and take 4 away, how many are left?”
  • Let students physically move the 4 beads aside and count what remains.

This visual, hands-on approach helps students see subtraction as taking away, not just counting backwards. You can also introduce missing part problems: “I have 10 beads. Some are red, some are blue. If 6 are red, how many are blue?”

Bead strings make these relationships concrete and help students internalise them, so subtraction stops feeling abstract or confusing. They pair particularly well with our ten frames resource for reinforcing part-part-whole thinking.

Transitioning Students from Bead Strings to Mental Strategies

Bead strings are excellent tools for early maths, but the goal is for students to eventually solve addition and subtraction problems mentally.

How to make the transition smooth:

  • Gradually reduce reliance on beads: Let students first count on the string, then visualise the jumps in their mind.
  • Encourage them to substitute beads mentally: Ask questions like “You know there are 5 red beads, how many more to make 10?”
  • Use number sentences alongside the beads: For example, 7 + 5 = 12. Students can see the physical jump and then connect it to the written symbols.

Over time, the physical beads become an internal image, helping students solve problems in their heads with confidence.

Creative Extensions: Multiplication, Division, and Place Value

Once students are confident with addition and subtraction, bead strings can support more complex topics:

  • Multiplication: Make groups of beads. 3 groups of 4 beads = 12. Students count in multiples.
  • Division: Share beads into equal groups. 12 beads divided into 3 groups = 4 each.
  • Place Value: Use different colours for tens and ones. 2 red beads + 7 blue beads = 27.

For a deeper dive into place value specifically, the Place Value Masterclass is a great next step for teachers wanting to extend this work with their class.

Bead strings are simple, but powerful. They make counting meaningful, reveal relationships between numbers, and prepare students for mental maths. Start small: try one addition activity, then subtraction. You’ll soon see students solving problems more confidently and explaining their thinking clearly.
