Fractions
9 topics in teaching order, each under ten minutes to read, each ending with practice questions that mark themselves.
What Is a Fraction?
The starting point. What the top and bottom numbers mean, why the parts must be equal, and fractions on a number line.
Math · Grades 2 to 4StartEquivalent Fractions
Fraction walls, number lines, the multiply and divide rule, and the three mistakes children actually make.
Math · Grades 4 to 6StartSimplifying Fractions
Dividing top and bottom, spotting the highest common factor, and knowing when a fraction is actually finished.
Math · Grades 5 to 7StartComparing Fractions
Same denominator, same numerator, and the common denominator method that never fails.
Math · Grades 4 to 6StartAdding and Subtracting Fractions With the Same Denominator
Counting pieces of the same size, why the denominator never changes, and tidying the answer at the end.
Math · Grades 4 to 6StartAdding Fractions With Different Denominators
Finding a common denominator, recutting both fractions, and the check that catches a wrong answer in two seconds.
Math · Grades 5 to 7StartFinding a Fraction of a Number
Divide by the bottom, multiply by the top. Why that order, and the sale-price questions it unlocks.
Math · Grades 4 to 6StartMixed Numbers and Improper Fractions
Improper fractions are not mistakes. Converting both ways, and when each form is the useful one.
Math · Grades 5 to 7StartFractions to Decimals
The hundred square, the divide method, and the eight conversions worth knowing by heart.

Decimals and percentages
7 topics in teaching order, each under ten minutes to read, each ending with practice questions that mark themselves.
What Are Decimals?
The decimal point, tenths and hundredths, reading them aloud, and why 0.7 beats 0.35.
Math · Grades 4 to 5StartComparing and Ordering Decimals
Column by column from the left, the zero padding trick, and why longer does not mean bigger.
Math · Grades 4 to 6StartAdding and Subtracting Decimals
Lining up the points, filling gaps with zeros, and estimating first so a wrong answer cannot survive.
Math · Grades 4 to 6StartRounding Decimals
Which digit decides, why five goes up, and the chain rounding trap that turns 4.46 into 5.
Math · Grades 5 to 7StartWhat Are Percentages?
Per hundred, the benchmarks worth memorising, and why 100% is not a ceiling.
Math · Grades 5 to 7StartFinding a Percentage of a Number
The 10% building block, sale prices, and the shortcut that makes 15% a mental calculation.
Math · Grades 5 to 7StartFractions, Decimals and Percentages
Every conversion in both directions, the table worth memorising, and how to order a mixed list without guessing.

Science: matter and the water cycle
5 topics in teaching order, each under ten minutes to read, each ending with practice questions that mark themselves.
What Is Matter?
Particles, mass and volume, and why air counts as matter even though you cannot see it.
Science · Grades 3 to 5StartSolids, Liquids and Gases
Particle arrangement in each state, shape and volume, and why only gases can be squashed.
Science · Grades 3 to 6StartChanging State
Melting, freezing, evaporating and condensing, the two temperatures for water, and why nothing new is ever made.
Science · Grades 4 to 6StartThe Water Cycle
The four stages, the words examiners want, and why the cycle has no beginning.

Whole numbers
10 topics in teaching order, each under ten minutes to read, each ending with practice questions that mark themselves.
Place Value to 1,000,000
What each digit is worth, why the zeros matter, and how to read a seven-digit number out loud without guessing.
Math · Grades 4 to 6StartRounding Whole Numbers
Nearest ten, hundred and thousand, why the halfway rule exists, and how to stop rounding the wrong digit.
Math · Grades 4 to 6StartAdding and Subtracting With Regrouping
Column addition and subtraction, what carrying really is, and how to handle a row of zeros without panicking.
Math · Grades 3 to 5StartTimes Tables That Actually Stick
Arrays, why 3x8 and 8x3 are one fact, and the short list of facts that are actually worth drilling.
Math · Grades 3 to 5StartMultiplying by 10, 100 and 1000
Digits moving columns, dividing as the same move backwards, and why 'add a zero' is a rule with an expiry date.
Math · Grades 4 to 6StartLong Multiplication, Step by Step
The area model, the written method, and the real reason the second row ends in a zero.
Math · Grades 4 to 6StartShort Division
The full working written out the way you would on paper, then how it compresses into the bus stop.
Math · Grades 4 to 6StartLong Division, Step by Step
Every step drawn on the real layout, so you can see where each number goes rather than being told.
Math · Grades 5 to 7StartFactors, Multiples and Primes
Factor pairs, the difference between factors and multiples, and why 1 is not a prime number.
Math · Grades 5 to 7StartOrder of Operations
Why an agreed order exists at all, the four levels rather than six, and the left-to-right rule people forget.

Forces and Motion
Pushes and pulls, reading a force diagram, and why a car at a steady speed has balanced forces.
Science · Grades 4 to 7StartFriction
Why rough surfaces slow things down, where friction is useful, and what happens to the energy it takes.
Science · Grades 4 to 6StartGravity, Mass and Weight
Why mass stays the same everywhere, how weight is worked out, and what actually happens on the Moon.
Science · Grades 5 to 7StartLevers and Simple Machines
Effort, load and fulcrum, why the pivot position is everything, and what you give up in return.
Science · Grades 5 to 7StartEnergy and Its Forms
The forms energy takes, transfer chains, and why nothing ever really uses energy up.
