Independent Reviewer
Dr. Sarah Bennett
Lead Mathematics Reviewer · Fun Math Kids
Lead Mathematics Reviewer independently verifying mathematical accuracy and curriculum alignment.
Why Independent Review Matters
A game can be delightful and still be wrong. Sarah’s review is the separate, sceptical read that authors can’t give their own work — verifying answers, checking that a "grade 3" activity really is grade 3, and catching the subtle mathematical slips that are easy to make and hard to notice.
About Dr. Sarah Bennett
Dr. Sarah Bennett independently reviews the mathematics behind Fun Math Kids. Her role is deliberately separate from the authors’: she checks that every number, answer key, and progression is correct, and that each activity honestly maps to the standard it claims. With a doctorate in mathematics education and years spent advising on grade-band standards, she looks specifically for the conceptual error patterns that quietly derail young learners — off-by-one counting, false fraction equivalence, and misleading visual models. Nothing carries her review mark unless the mathematics is right and the curriculum claim holds up.

The Review Process
Every resource moves through the same steps, in the same order, before it is approved for publication.
Research
Cross-reference the target concept against US, UK, CA, and AU curriculum documents for the intended grade band.
Mathematical Verification
Check every worked example, answer key, and game logic path for computational and conceptual accuracy.
Curriculum Standards Validation
Confirm the content maps cleanly to the stated grade level and learning objective, not just an adjacent one.
Developmental Suitability
Assess whether the difficulty, pacing, and presentation fit the intended age group.
Accessibility & Safety
Verify readability, contrast, and that nothing on the page is unsafe or confusing for a child.
Sign-off
Approve for publication only when every earlier step passes; otherwise return for revision.
Content Quality Standards
Accuracy
Every equation, answer key, and game rule is independently checked, not just spot-verified.
Curriculum Alignment
Content must match its stated grade level, not merely be “close enough” in difficulty.
Learning Outcomes
Each resource is checked against a clearly stated, measurable learning objective.
Age Appropriateness
Language, pacing, and visuals are verified as suitable for the target age band.
