Primary math
Build a connected foundation in number, calculation, fractions, measurement, and data. Use the skills in order or return to the first idea that needs attention.

School context: Primary / elementary foundations
Common primary-school ideas organized by understanding. Year and grade expectations vary by curriculum; the route does not assign a fixed age or claim an exact national-year match.
What this path connects
- Explain whole-number calculations using place value and the meanings of operations.
- Connect fractions and decimals to quantities.
- Use basic measurement and data skills alongside arithmetic.
The learning sequence
See what each unit covers and open the skill you want to understand. The order gives you a route through the material.
Unit 1
Count, compare, and name the places
Connect objects to numbers, then explain what the digits represent. These ideas make the written calculations in later units meaningful.
- Counting & comparingConnect a count to a quantity and compare numbers accurately. Use objects, number words, and a number line to explain more, fewer, and equal.
- Place valueExplain what each digit contributes to a number. Read zeros as placeholders and use place value to compare, split, and rebuild whole numbers.
Unit 2
Combine, separate, and make equal groups
Use addition and subtraction to describe quantities, then connect multiplication to repeated equal groups and place-value parts.
- Addition & subtractionChoose addition or subtraction from the situation and explain a written calculation. Use place-value exchanges and inverse operations to check your result.
- MultiplicationConnect multiplication to equal groups and arrays. Use place value and the distributive property to explain a larger product instead of treating the method as a trick.
Unit 3
Organize a larger division
Use multiplication facts, subtraction, and place value to follow long division. Explain and check the remainder rather than merely carrying out a sequence.
Unit 4
Represent parts of a whole
Explore equivalent fractions and decimal places. Keep the size of the whole and each fractional unit clear.
- Equivalent fractionsExplain why different fractions can name the same number. Scale the numerator and denominator together and connect the calculation to equal parts of one whole.
- DecimalsRead tenths and hundredths as fractional units. Compare decimal values and align place values when adding or subtracting them.
Unit 5
Measure, describe, and read information
Use arithmetic to reason about shapes, area, volume, and a small set of data. Relate every answer to the quantity being measured.
- Shapes & anglesDescribe shapes using their properties and reason about angles. Use stated relationships rather than the appearance of a drawing to find an unknown angle.
- Area & volumeDistinguish length, area, and volume before using a formula. Explain rectangular area and cuboid volume through equal units, then check the result’s dimensions.
- Reading dataRead a table or chart in context and summarize a small data set. Distinguish mean, median, and range instead of expecting one number to tell the whole story.
Make the path useful to you
Begin with a representation
Use a drawing, objects, or a number line when they explain the relationship. Connect the representation to the written notation instead of replacing one with an unexplained rule.
Check one small change
After a worked example, change a number or arrangement and ask what stays the same. Use the explanation to decide whether to continue or revisit the earlier skill.
Use school expectations as context
Long division and other written methods appear at different points in different curricula. Follow the actual class method and readiness; this path is a connected foundation, not a complete national syllabus.
