A complete IB DP Physics skill pack on significant figures and rounding (SL and HL, first assessment 2025), offered free as a full-quality sample of the premium YPhysics catalogue: a rules reference, six worked examples and more than 60 practice questions, all answered. Not a cut-down teaser but the whole pack, nothing watermarked and nothing held back.

Significant figures are a technique the syllabus assumes but no topic owns, and the IB asks for it to be practised inside the topics that need it. This is not a taught unit: it is reference and remedial material that supplements integrated teaching, for the first weeks or for a student losing marks on precision rather than physics.

This pack is worked, not taught: the 2 hours shown is student working time across the practice bank, not classroom delivery time. It sits as two sittings of about an hour.

What students learn:

  • Counting significant figures and decimal places, every kind of zero included, and the ambiguous 55 000
  • Rounding once from the original value, including a carried 9: 0.00030990 to 3 s.f. is 0.000310
  • Reading the answer back: 99.997 to 3 s.f. is 100, which claims one figure, so write 1.00 x 10^2
  • Decimal places for addition and subtraction, significant figures for multiplication and division
  • Stating a mean to the precision the instrument supports (2.30 s, trailing zero kept)

Three tiers: A, 35 fluency items, two sets inverted so students build a number to a stated condition; B, 16 applied calculations on speed, density, momentum, energy and g from a pendulum; C, four multiple-choice items, every distractor explained, and two structured questions worth 18 marks.

IB skills (Tool 3: Mathematics): the pack teaches expressing a quantity to an appropriate number of significant figures or decimal places; students practise basic arithmetic and algebraic calculation and scientific notation.

What’s included:

  • Student Worksheet (15 pages), answers stripped out, colour and printer-friendly B&W
  • Teacher Key (23 pages), every answer and model solution, plus teaching notes
  • The editable worksheet, a self-contained HTML file

The worksheet and the key are two projections of one source, so no answer file can drift. Grades 11-12 (ages 16-19).

IB DP Physics (2025) A.1 Kinematics Complete Unit Bundle

The complete Topic A.1 Kinematics unit for IB DP Physics, SL and HL, first assessment 2025, bundled into one sequenced teaching unit and priced 30% below the cost of buying the packs separately. **What's in the unit** - Nine lesson packs in teaching order: Distance and Displacement, Speed and Velocity, Acceleration and Non-Uniform Motion, Graphical Analysis of Motion, SUVAT Equations I and II, Projectile Motion I and II, and Fluid Resistance. - A1.P1, a full double-period bench practical measuring the acceleration of free fall, aim to evaluation, with honest sample data. - SL and HL topic tests with AO-tagged mark schemes, for end-of-topic assessment. - Skill packs for targeted drill on scientific notation, significant figures and unit conversion. Together the lessons cover all nine understandings of Topic A.1: position, displacement, velocity and acceleration, motion graphs, the four suvat equations, projectile motion, and the qualitative effect of fluid resistance. **Every lesson pack includes:** - An editable student worksheet - A teacher key with every answer and marking point - Worked solutions with every step and its units - A questions-only assessment with IB mark allocations - A choreographed lesson deck with staged reveals **IB skills (mostly Tool 3: Mathematics)**: identifying scalars and vectors, determining rates of change, drawing and adding vectors, converting units, selecting and rearranging the suvat equations, resolving vectors into perpendicular components, interpreting and sketching motion graphs, and linearizing data. The practical adds Tool 1 experimental technique and the Inquiry skills: measuring time and length, recording and propagating uncertainties, plotting best-fit lines, and evaluating error sources. Everything ships as self-contained HTML, so worksheet and deck open in any browser with nothing to install and the worksheet is fully editable, plus colour and black-and-white PDF of every projection and the slides. SI units, IB notation and IB command terms throughout. A1.1 is free, so you can teach a whole lesson before buying. Suitable for grades 11-12 (ages 16-19) for first teaching, assessment and revision. **Also in the catalogue, sold separately:** - [Resolving Vectors, the skill pack behind the projectile lessons](/teaching-resource/-13537892) - [Uncertainties, the arithmetic the practical leans on](/teaching-resource/-13538960) - [Uncertainties on a Graph, error bars and extreme gradient lines]( /teaching-resource/-13542412)
