Synthesis uses adaptive AI tutoring to build primary maths understanding

Synthesis is an education company with an adaptive digital maths tutor and a separate live collaborative-learning programme. Tutor is designed to help children work through primary maths with guidance that responds to their answers. The useful question for a family is whether a child understands and can apply the idea after the session, rather than whether the experience feels engaging.

01 / ProductTutor and Teams address different kinds of learning

The company overview describes Synthesis Tutor as an adaptive AI maths product for ages 5–11, covering K–5 topics such as arithmetic, fractions and algebraic thinking. The company says educators design the lessons and pedagogy, with AI used within that experience. It should therefore be understood as a structured learning product rather than an open chat in which a child can ask for any school subject.

The Teams overview describes a distinct live programme for ages 8–14, centred on collaborative games and discussion. Children practise explaining ideas, making decisions with others and responding to unfamiliar problems. Tutor and Teams require separate memberships. A parent seeking individual maths support should not assume that a Tutor purchase also provides a scheduled group class or a live human tutor.

This separation is useful when deciding what problem to solve. A child who needs help understanding fractions may benefit from repeated individual practice; a child who struggles to explain an idea to peers needs a different experience. The same company offers both, but a successful trial of one product does not establish the fit of the other. Set a concrete learning purpose before comparing subscriptions.

02 / AudienceLook for a specific primary-maths need

A suitable starting point is a child who can attempt a problem but needs a more patient explanation or a different representation. A family can focus on a topic such as place value or multiplication, observe the interaction and ask the child to explain it afterwards. The product’s stated age range is a guide to its content, not a diagnostic judgement about an individual child’s needs or readiness.

The Tutor page describes read-aloud options, adjustable voice speed and interactive learning. These may help a child engage with the material, but the company’s broad claims about particular learner groups are not a substitute for checking an individual child’s needs. A parent or educator should evaluate the actual interface, instructions and pace rather than infer that a general accessibility feature guarantees a good fit.

Compare Khan Academy when a wider curricular pathway is important. Duolingo provides another example of adaptive learning and practice, but its subject range and activities differ. Synthesis is most directly considered for a specific primary-maths routine. If the requirement is advanced secondary mathematics, live individual teaching or a broad school curriculum, establish the content boundary before committing.

03 / WorkflowA proposed trial that checks understanding away from the screen

Choose one manageable objective for the trial: for example, explaining why two fractions can represent the same quantity. Before the first session, ask the child to show the idea with paper shapes or objects. Keep the task informal and record the explanation rather than turning the trial into a high-pressure test. The purpose is to see what the child already understands and what kind of help is needed.

Use Tutor for a short session and observe how the child responds to guidance. Notice whether they read or listen to the explanation, make a reasoned choice or simply try answers until the lesson advances. If the interface itself is confusing, address that before judging the mathematical teaching. An adaptive system’s next task can only be interpreted sensibly when the child understands what the interface is asking.

Afterwards, ask a similar question using a different representation, such as folded paper instead of an on-screen diagram. Invite the child to explain the reasoning in their own words. Repeat the idea later without the tutor. This is a proposed check of transfer and retention, not a claim that we measured either with Synthesis. A useful outcome is a clearer explanation or a more independent solution on a new example.

Keep the routine short enough to distinguish learning from fatigue. A child may enjoy an activity while still missing the concept, or understand it while disliking a particular interaction. Record those separately. If the child repeatedly reaches for adult help, inspect whether the difficulty comes from the maths, reading, device controls or instructions. That observation is more useful than a single completion percentage.

04 / PricingThe current family offer is separate from live classes

The family offer can change the buying calculation when several children need maths practice, but access for seven children has value only if those children use it. Check each child’s age, curriculum and willingness to work independently. The About page also displays the annual family offer. Confirm the currency, available plan and renewal date at checkout, and keep the separate Teams reservation charge in the budget if considering live classes.

The terms of service say Tutor renews according to the chosen billing cycle and that cancellation retains access through the paid period, without partial-period refunds except where required. Check the exact trial and renewal conditions at registration. A low annual equivalent is useful only if the product fits the child and the family intends to use it for that period; the monthly route may provide a more limited commitment during evaluation.

05 / DistinctionsAdaptive interaction should reveal the child’s reasoning

The distinction from a worksheet is the opportunity to respond to the child as the activity unfolds. A worksheet can reveal that an answer is wrong; an interactive tutor may be able to guide the next attempt. The practical value depends on whether that guidance addresses the underlying misconception. Repeating a different-looking question is not necessarily useful if the child is applying the same mistaken rule.

Synthesis describes continuous checks of understanding and progression after mastery in its Tutor explanation. Treat this as the company’s account of the product, not an independent guarantee that every learner has mastered each topic. Parents can use the separate, unaided activity in the proposed trial to assess whether screen-based progress corresponds to understanding in another setting.

The educator page extends the offer to classroom settings. For a teacher, the meaningful question is how individual practice connects to the next lesson. A progress report can suggest where to intervene, but the teacher still needs to interpret it alongside the student’s explanation and classroom work. The best use of a digital tutor may be targeted practice within a wider teaching relationship rather than replacing that relationship.

06 / QuestionsCheck account supervision, devices and curriculum fit

The privacy policy requires a parent or guardian to create the account for a child and describes collection of learning and interaction data, including attempted problems and progress. That makes supervision and account setup part of the product decision. Review the applicable family or school arrangement and understand what information adults can access before asking a child to use the service independently.

Check the intended device during the trial. A lesson that feels straightforward on a larger screen may be less comfortable on the family’s available tablet. Listen to the audio, inspect the controls and verify the language needed by the child. Avoid treating a product’s general device list as proof that an older device, unreliable connection or particular accessibility setup will support a satisfactory session.

Curriculum alignment also needs a concrete check. The product’s K–5 description uses a US educational framing; a family elsewhere should compare the topic sequence and notation with the child’s school work. An enrichment activity can be useful even when it follows a different order, but parents should recognise that difference. If the child needs specialist support, discuss the proposed practice with the relevant educator rather than infer suitability from marketing testimonials.

Finally, keep the child’s own experience in the evaluation. Ask which explanation made sense and which part felt confusing. A parent’s impression of a polished interface is not the same as the learner’s experience. The decision should consider independence, willingness to return and understanding, with enough room to stop or change approach when the routine is not helping.
