Nico answered every question on Frac/Decimal Conversion this month — a Year 5 topic practised while still in Year 4. That is a genuine wow: moving between fractions and decimals requires holding the part-whole idea in two forms at once, and Nico did it cleanly.

What makes this stand out even more is the pace. Nico worked through these questions noticeably faster than the lifetime average, which suggests the thinking has become automatic rather than effortful. That kind of fluency is exactly what frees up mental space for harder problems ahead.

Earlier in Nico's practice history, Rounding and Estimation was only around a third accurate. This month Nico got every attempt right. That is a clear recovery arc — the concept has settled.

The mechanism that clicked here is knowing when to round up versus down based on the digit that follows — a judgement call, not just a rule to remember. Nico is now making that call reliably, which will directly support estimation work with square roots coming up.

Simplify & Common Denoms showed up across several sessions this month with steady accuracy. The work here is not flashy, but it is the kind of foundation that keeps harder fraction topics from wobbling later.

Nico is finding common denominators and simplifying without pausing to re-derive the steps each time. That automaticity is what the Year 5 fraction line will lean on when multiplication and division of fractions enter the mix.
