Place value and rounding
Ten counters make a ten, ten tens make a hundred. Once you have seen the bundling, reading millions and rounding them is no longer a mystery.
MathematicsRhineland-Palatinate curriculum · Gymnasium
Orientation stage (grades 5 and 6): the framework curriculum describes both grades together and in no fixed order, so the units are the same for grades 5 and 6 and are shown as one stage. Units are the content areas of the key ideas L1–L5, sub-units their sections; the numbers are our own. Optional extras marked (+) are not compulsory.
Extending the number range beyond one million, mental, written and estimated calculation, structuring terms and examining divisibility.
Reading and writing large numbers, explaining the place-value system, ordering, rounding and showing numbers on the number line; the binary system as an optional extra.

Ten counters make a ten, ten tens make a hundred. Once you have seen the bundling, reading millions and rounding them is no longer a mystery.
Mental and written methods, simple powers, estimating, structuring terms with calculation trees, solving simple equations and using the laws of arithmetic.

From a grain of sand to the Earth in steps of ten. Along the way it becomes clear why 10⁶ is a million and how to write tiny numbers.

An expression drawn as a tree: whatever hangs lowest is calculated first. The order of operations stops being a rule and becomes visible.
Applying divisibility rules for 2, 3, 4, 5, 9 and 10 and meeting prime numbers as the building blocks of natural numbers.

Break numbers down into prime factors, check divisibility rules and find primes with a sieve. This also gives you the gcd and the lcm.
Interpreting negative numbers from everyday life, ordering them on the number line and calculating changes of state.
Interpreting signed numbers in contexts such as temperature or bank balance, ordering them on the number line and plotting them in the coordinate system.

A frog hops past zero into the negatives. Thermometers and bank balances show why minus 3 plus 5 makes exactly 2.
Solving word problems as a change from a starting state to an end state, evaluating simple terms and solving equations; the second operand stays positive.

An expression drawn as a tree: whatever hangs lowest is calculated first. The order of operations stops being a rule and becomes visible.
Building a sound concept of fractions, writing them as fractions, decimals and percentages, and calculating with positive fractions.
Interpreting fractions as measures and operators, calculating parts, writing them as fractions, decimals and percentages, expanding, simplifying, comparing and ordering.

Pizza, cake or a line: share it out fairly first, then colour some pieces. That is exactly what a fraction means.

Compare two fractions as bars or circles. When you expand a fraction, the pieces get smaller but the amount stays the same.

Why does 1/4 end as a decimal but 1/3 never does? Long division gives it away as soon as a remainder repeats.

Discounts, VAT, surveys: one single bar holds the base value, the percentage and the part, one above the other.
Adding, subtracting, multiplying and dividing fractions and decimals, reading the fraction operator as a factor and applying it in real contexts.

Two strips overlap in a rectangle: the shared area is the product of the fractions. Dividing by a fraction is shown visually as well.

Why does 1/4 end as a decimal but 1/3 never does? Long division gives it away as soon as a remainder repeats.
Measuring as comparing with a unit: length, mass, time, angle, area and volume; formulas for rectangle and cuboid; calculating with quantities and scale.
Measuring and estimating lengths, masses, time spans, angles, areas and volumes with units; deriving perimeter and area of the rectangle and volume and surface area of the cuboid.

Line up the protractor, hit the zero point, read the right scale. The estimation game then shows how well your eye already measures.

Count the squares or walk once around? An ant makes the difference between area and perimeter tangible.

First a row of cubes, then a layer, then the whole cuboid. Length times width times height follows naturally from filling it.
Converting quantities between units, using prefixes and decimal notation, rounding sensibly in real contexts, applying scales and formulas.

3.5 km is 3500 m, but 3.5 m² is 35,000 cm². The unit table shows why the decimal point jumps twice as far for areas.

Measure on a map with a ruler and use the scale to work out the real distance.
Recognising and creating symmetric figures, drawing angles and circles, describing solids and quadrilaterals, nets and oblique drawings, coordinate system.
Line and rotational symmetry, parallel and perpendicular, lines, segments and distance, estimating, measuring and classifying angles, drawing circles.

In a line or in a point: the shape flips over, and every construction step with the set square stays visible.

Place and read points in a coordinate system, draw segments and lines and check whether they are parallel or perpendicular.

Line up the protractor, hit the zero point, read the right scale. The estimation game then shows how well your eye already measures.
Recognising cubes, cuboids, pyramids, cylinders, cones, spheres and prisms, describing and drawing quadrilaterals, making nets and oblique drawings, working in the coordinate system.

Fold nets of a cube, cuboid, prism, pyramid and cylinder into a solid in 3D and calculate the surface area.

Move one corner and the square becomes a kite. When does a quadrilateral get which name?

Place and read points in a coordinate system, draw segments and lines and check whether they are parallel or perpendicular.
Not taught separately in the orientation stage: sequences, terms, the operator model, formulas, scale and data displays prepare the functional view within the other key ideas.
No separate simulation is planned for this.
Counting with tree diagrams, and collecting data, analysing it with frequencies and the mean and showing it in charts.
Developing counting methods in concrete situations such as combination locks and showing them in tree diagrams.

How many outfits or ice cream combinations are there? A tree diagram grows step by step and shows why you multiply the options.
Planning and analysing surveys, absolute and relative frequency, the arithmetic mean, reading charts and checking them for manipulation.

Show the same data as bar, line and pie charts and more, and discover how charts can mislead.

One outlier pulls the mean away while the median barely moves. Dragging single data points shows which value is how robust.
