Children writing at their desks

G3–4 Math Lab

Students learn fractions, decimals, and basic shapes, then redo the problems from school, this time as easy English word problems.

They also study length, time, liquid volume, weight, angles, and 2D shapes, and practice finding the conditions in a word problem to set up an equation.

What your child learns in grades 3–4

Students check the concepts they learned at school, then learn the English math terms used in that unit.

Solving easy English word problems

Students read Easy Word Problems in English in parts, find the conditions and what to solve for, and turn them into equations.

  • Grade 4: large numbers and patterns; multiplication and division; line graphs; adding and subtracting fractions and decimals; angles, moving shapes, triangles, quadrilaterals, and polygons

Similar topics in US and UK curricula at about the same age

  • US curriculum, Grade 3: Multiplication, Division

The grade in which each topic is taught varies by school.

Solve independently, then redo mistakes

Units your child finds hard to solve alone get more class time.

The steps in a G3–4 Math Lab class: a new concept and key problems, explaining the solution, then finding out what went wrong and solving again
  1. Step: Learn a new concept and solve key problems

    At this step, your child: Learns the current unit's concept from examples and applies it to key problems.

  2. Step: Explain the solution

    At this step, your child: Points to the conditions in the problem and says why they chose that calculation.

  3. Step: Find out what went wrong and solve again

    At this step, your child: Checks whether they misread the word problem or made a calculation error, then solves a similar problem again without help.

A quiz every class checks what your child learned

Each quiz checks the answer and whether your child found the conditions in the word problem. The problems they got wrong go into their portfolio.

We share what the quiz shows with you too. See how parents get progress updates
