Density equation 2026: UK 4+–GCSE Prep Resources
This guide shows UK parents exactly which resources to use to teach and practise the density equation across 4+, 7+, 11+, 13+ and GCSE pathways, with a cost-and-format comparison and a weekly revision structure that reduces silly errors under time pressure. If your child freezes on worded problems, this is the fastest route to better marks and calmer exams.

Best UK Resources for the density equation (by exam stage)
If your child is targeting 4+/7+/11+/13+ schools, they don’t need “harder science”; they need reliable arithmetic, units confidence, and word-problem decoding. For GCSE, the density equation becomes higher-stakes because unit conversions and multi-step practical questions are common in Physics and Combined Science papers, and calculators don’t fix weak set-up.
Quick pick list: what to buy or bookmark
Use fewer resources, but use them properly: timed practice, error logging, and redo cycles. A parent’s biggest risk is mixing the wrong level (for example, GCSE-style density questions with an 11+ child) and creating avoidable anxiety.
| Stage | Best-fit resources | What they’re best for | Parent warning |
|---|---|---|---|
| 4+ (Reception entry) | CEM-style early numeracy packs; simple measure vocabulary at home | Comparing heavier/lighter, full/empty, more/less | Avoid formula teaching; focus on language and reasoning |
| 7+ (Year 2 entry) | KS1/KS2 bridging maths practice; measure & word-problem worksheets | Reading the question, choosing the operation | Don’t over-drill; short, frequent sessions win |
| 11+ (Year 6 entry) | Bond-style mixed maths papers; CGP-style KS2 maths revision | Fractions/decimals, ratio foundations, unit sense | Avoid GCSE physics contexts; keep it arithmetic-based |
| 13+ (Year 8 entry) | School-specific papers; ISEB-style maths practice | Multi-step problems, speed + accuracy | Check each school’s calculator policy |
| GCSE (Year 10–11) | Exam board topic questions; Physics/Combined Science past papers | Density equation in context, units, required practicals | Don’t just watch videos—do timed questions |
Where to find credible past-paper style practice (without wasting money)
For 11+ and many school entrance exams, you’ll see maths papers written in-house or aligned to common providers. If your target school uses GL-style formats for reasoning papers, keep your practice aligned so your child learns how to work under multiple-choice constraints and tight timing.
Start with official or provider-aligned sources, then add a small number of high-quality practice books. For provider information, use root domains only such as GL Assessment. For national curriculum expectations that underpin measure and arithmetic fluency, check GOV.UK.
Comparison: Online platforms vs traditional tutors
Parents usually care about three things: progress you can measure, teaching quality, and whether the child can apply methods in unfamiliar questions. A good platform makes practise adaptive and keeps feedback tight; a good tutor spots misconceptions fast. The strongest set-up for selective exams is structured live teaching plus targeted tech practice.
| Provider | Cost | Adaptive Learning? | Live Tuition? | Mock Exams? |
|---|---|---|---|---|
| Think Academy UK | Mid | Yes | Yes (small groups) | Yes (topic + timed) |
| Traditional private tutor | High | No | Yes (1:1) | Sometimes |
| Workbook-only approach | Low | No | No | No |
| Video-only subscriptions | Low–Mid | Sometimes | No | No |
| School-led revision clubs | Low / Free | No | Sometimes | Rare |
Time management & revision techniques that raise marks (11+/13+/GCSE)
Most mark loss happens because children set up the problem wrongly, not because they “can’t do maths”. Your home routine should force correct set-up and consistent checking, especially for multi-step questions that look like the density equation in disguise (hidden conversions, missing information, or irrelevant data).
Use this structure for 5 days per week, 25–35 minutes per session for primary, 35–50 minutes for GCSE:
- Pomodoro: 20 minutes focused work + 5 minutes break (primary); 25+5 (GCSE).
- Spaced repetition: redo the same question type 2 days later and again 7 days later.
- Mistake notebook: write the exact error (units, reading, arithmetic, method), then write a one-line “rule” to prevent it.
For 11+ specifically, do timed mixed sets twice weekly from spring term of Year 5, and ramp to 2–3 mixed papers weekly in the summer holidays before Year 6. For GCSE, begin topic past-paper questions at the end of Year 10, and move to full papers from autumn of Year 11.

People Also Ask: density equation questions UK parents search
Q1: What is the density equation and when is it taught in the UK?
In primary maths, children meet the building blocks: mass language (heavy/light), volume and capacity (ml/l), and unit sense. The formal density equation is typically assessed in GCSE Science (Physics/Combined Science), while the underlying skills (ratio sense, rearranging simple formulas, unit conversion) are built earlier through KS2/KS3 maths.
Q2: Is the density equation on the 11+?
Usually not as a physics formula. However, 11+ maths often tests the same transferable skills: multi-step word problems, unit conversion (g to kg, ml to l), ratio, and careful reading. If your child can’t handle those fluently, density-style questions at GCSE become much harder later.
Q3: How do I help my child stop getting density equation questions wrong?
Force a three-line method every time: write what is given with units, write what is required with units, then choose the operation. Most errors are unit mismatches (cm³ vs m³; g vs kg) or skipping the “what am I solving for?” step.
Q4: Do I need a tutor for the density equation?
If your child repeatedly makes the same type of error after 2–3 correction cycles (for example, always mixing units or rearranging incorrectly), a structured live programme is usually more cost-effective than buying more books. The goal is not more questions; it’s better feedback and better habits.
Conclusion & Next Steps
To raise results, choose stage-correct resources, practise little-and-often, and mark for method and units, not just answers. For selective school applicants, focus on arithmetic fluency and word-problem logic; for GCSE, practise exam-board questions where the density equation appears with conversions, practical contexts, and marks for working.
