📏Oxford Mathematics Grade 3

Grade 3 is where written methods arrive properly, and where many homeschooling parents hit their first real difficulty — not because the maths is hard, but because they were taught a different method thirty years ago and do not want to confuse their child.

Every formal method in this course comes with a one-page reference sheet for the adult, showing the exact layout and language used, plus a short video explaining why this method is taught this way. You will not have to improvise.

What your child will be able to do

By the end of this course, a learner working at the expected pace will be able to:

• Recall all times tables to 12 × 12 with speed and accuracy
• Multiply two- and three-digit numbers by a single digit in columns
• Divide using short division with remainders
• Add, subtract and compare fractions with the same denominator
• Calculate perimeter and find area by counting squares

How the course is structured

Oxford Mathematics Grade 3 is organised into 6 units covering 170 lessons in total, designed to run across 36 weeks at roughly 4.5 hours a week. The unit outline below shows 24 representative lessons.

Number to 10,000

• Thousands, hundreds, tens and ones
• Rounding to 10, 100 and 1000
• Negative numbers on a thermometer
• Roman numerals to 100

Completing the tables

• 6s, 7s, 9s, 11s, 12s
• Spotting patterns to reduce memorisation
• Mixed tables sprints
• Factors and multiples

Formal multiplication

• Grid method as a bridge
• Short multiplication in columns
• Three digits by one digit
• Multiplying by 10, 100 and 1000

Formal division

• Short division introduced
• Remainders and what to do with them
• Division word problems
• Checking with multiplication

Fractions and decimals

• Equivalent fractions with a fraction wall
• Adding and subtracting same-denominator fractions
• Fractions of amounts
• Tenths as decimals

Measure and geometry

• Perimeter of rectilinear shapes
• Area by counting squares
• Angles: right, acute, obtuse
• Time: 12- and 24-hour clocks

How it is taught

Methods are introduced through the grid method before the column algorithm, so children understand what the compressed notation is standing in for. Remainders are handled in context from the start rather than as an abstract 'r 3'.

What is included

• 170 lessons with step-by-step method videos
• Fraction wall, grid-method templates and 160 worksheets
• 44 quizzes, six unit tests, one mid-year paper
• Method reference sheets for parents who were taught differently

Who this course suits

This course sits in the Grade 3 track and follows a oxford-aligned sequence. It suits families who want a complete, sequenced mathematics year rather than a set of loose practice activities, and it assumes no teaching experience — every lesson includes a short method note for the adult. If your child is comfortably ahead or behind the intermediate level described here, use the placement check in lesson one and start at the recommended point instead of lesson one.
