The Fraction Circle
Drag pieces, build fractions and see how they fit togetherGrades 4–6Addition – unlike denominators
14+16=312+212=512
Conversion:1/4 = 3/121/6 = 2/12
Correct! With a common denominator the pieces are the same size – then you can add them together.
Fractions with Lydia
Fractions get hard when they are only digits. In the Fraction Circle your child drags out the pieces and sees that 1/4 and 1/6 are different sizes. With a common denominator the pieces become the same size – then you can add them together. The same piece is also shown as a percentage and a decimal.
Guiding question: Why do the pieces need to be the same size before you can add them?

The Lydia method
See → Do → Say → Write
Our teaching approach makes maths understandable – with visual support, small steps and encouragement.
- 01
See
Your child sees the concept in a picture or model.
- 02
Do
Your child tries it out with interactive models.
- 03
Say
Your child explains their thinking.
- 04
Write
Your child writes down their thinking with pen and paper.
Four principles
Visual learning
Diagrams, animations and models make abstract ideas concrete.
Micro-steps
Complex concepts are broken down into small, manageable steps.
Socratic guidance
Thoughtful questions instead of direct answers.
Confidence first
Encouragement that helps children dare to try and keep going.

Visual learning, step by step
Many students struggle with maths because it feels abstract. Lydia makes concepts concrete with interactive models – see how a student solves a problem with support from the AI coach.
Visual tens
The student sees that the “4” in 47 is four tens. Numbers become concrete objects.
Interactive regrouping
Ten ones become a new ten. The student experiences the maths – instead of just reading about it.
Logical carrying
No magic rules – the student understands why the digit is carried.
Lydia's dyslexia support · Grades F–3
Maths you can listen to, see and do
For students with reading and writing difficulties. Your child chooses how the text should look and lets Lydia read aloud – so that it is the maths being practised, not the reading.
How it works
- ListenLydia reads questions, explanations and next steps aloud. With “Read aloud automatically” it happens on its own.
- Text sizeThree sizes. Short sentences with one idea at a time.
- Spacing“Airy” gives more space between words and lines, so the text is easier to follow.
- BackgroundWhite, light blue, light green or cream – your child chooses what is most comfortable to read on.
- Pace“Calm” reads more slowly and gives more time – no time pressure.
- Go backYour child can always go back a step and listen again.

Measuring and weighing

Length is measured in metres and centimetres.
Weight is measured in kilograms and grams.
Built into every step – in every topic
The settings follow your child through the whole Lydia method. Your child sets them once – then they apply in every topic and every step.
- SeeThe explanation is shown as a picture and read aloud. Short sentences, one idea at a time.
- DoThe instruction is read aloud before your child starts. Your child works with models instead of long word problems.
- SayYour child explains their thinking out loud – understanding is shown orally before anything has to be written.
- WriteLarger text and airy spacing. Your child can listen again before writing with symbols or pen and paper.
- Try it yourselfThe same support is still there. Calm pace and no time pressure – your child shows what they can do.

Everyday life with Lydia
“Elias went from an E to a C in just one term. He now picks up the tablet on his own to practise maths – I never thought that was possible!”
“Saga has dyslexia and found it hard to read the maths problems. With Lydia's built-in read-aloud it finally works without her having to ask for help all the time.”
“The family plan is worth its weight in gold. All three children have their own profiles and I see their progress in one single view. Highly recommended!”
