Several genuinely harder ideas land in the same year. Here's what tends to cause the most difficulty, and why.

Year 5 has an unusually high concentration of genuinely new, harder ideas landing in a single year — which is worth knowing if your child suddenly seems to be finding maths tougher than they did in Year 4. It's rarely a sign of a wider problem; it's often just that several real conceptual jumps have arrived at once.
This is usually the single biggest hurdle of the year. Adding 1/3 and 1/4 requires finding a common denominator first, which is a genuinely multi-step process compared to the same-denominator addition children have been doing since Year 3. It's worth reading more in Year 5 fractions: a complete parent's guide if this is where your child is stuck.
Negative numbers were introduced in context (temperature, for example) back in Year 4, but Year 5 asks children to use them more actively — counting forwards and backwards through zero, and interpreting negative numbers in a wider range of situations. Crossing zero is the conceptually tricky part: children who are completely fluent with positive numbers can genuinely struggle with the idea that continuing to count down past 0 doesn't stop or reset, it just becomes negative.
Multiplying a four-digit number by a two-digit number involves several intermediate steps and multiple opportunities for a small slip — in the times-table facts, in the carrying, or in correctly aligning the columns of the intermediate results — to throw off the final answer. A wrong final answer here doesn't necessarily mean anything conceptual is misunderstood; it's often a single step, in an otherwise correct method, that went slightly wrong.
These are genuinely new vocabulary and genuinely new ways of thinking about numbers — not "what does this number equal," but "what numbers divide into it evenly, and what does that tell us." Children who are strong at calculation can still find this abstract, because it asks them to reason about relationships between numbers rather than just compute an answer.
Using a protractor accurately is a genuine fine-motor and procedural skill on top of the maths itself — lining it up correctly, reading the right scale (most protractors have two, going in opposite directions), and reading it to the nearest degree. It's common for a child who understands angle facts perfectly well conceptually to still get inaccurate answers purely from protractor handling, which is worth recognising as a separate skill rather than a maths misunderstanding.
If your child seems to be finding maths noticeably harder in Year 5 than they did the year before, it's worth remembering this is a genuinely dense year for new ideas, not necessarily a sign of a developing gap. The useful response is the same as always: work out which specific topic is causing difficulty, rather than treating "maths" as uniformly harder now.
Grasp Maths tracks each of these Year 5 topics as a separate skill, so if fractions are the sticking point but factors and multiples are fine, that distinction is visible immediately — rather than one dip in overall confidence looking like a problem across the whole subject.
