Math games for 3rd graders
Third grade is the multiplication year. By the end of it, most schools expect children to know every product of two one-digit numbers from memory, and to see fractions as numbers in their own right, not just shaded parts of a shape.
Here is what 3rd graders usually learn in math, which Clarendium games match it at the 3rd grade level, and a free level your child can play now.

What 3rd graders learn in math
Under the Common Core standards, which most states follow closely, 3rd grade covers:
- Multiplication and division within 100. Understanding multiplication as equal groups and arrays, division as sharing and grouping, and knowing all products of two one-digit numbers from memory by the end of the year.
- Fractions as numbers. Unit fractions such as 1/4, fractions on a number line, simple equivalent fractions such as 1/2 = 2/4, and comparing fractions with the same top or bottom number, using halves, thirds, fourths, sixths and eighths.
- Adding and subtracting within 1,000. Fluently, using place value, plus rounding to the nearest 10 or 100.
- Area and perimeter. Area by counting unit squares and by multiplying side lengths; perimeter of shapes with straight sides.
- Time, measurement and data. Telling time to the minute, measuring liquid volume and mass, and reading picture and bar graphs.
Which Clarendium games fit 3rd grade
With “Grade 3” chosen as the practice level (the button above sets it), the worlds pitch their questions at 3rd grade:
- Multiply Mountain (multiplication): multiplication facts drawn as equal groups, building across the three stages to every fact up to 10 × 10 at the summit. Choose Grade 4 or 5 for the 11 and 12 times tables.
- Fraction Falls (fractions): shapes split into thirds, fourths, fifths, sixths and eighths; your child names the colored part and learns what the top and bottom numbers mean.
- Number Grove (addition): addition with two- and three-digit totals, with hints that split numbers into easier steps.
- Subtraction Shores (subtraction): subtraction with larger numbers, each answer checked by adding back.
Not covered yet: division, area and perimeter, time and graphs. At Grade 3 the times tables stop at 10 × 10; the 11s and 12s start at Grade 4.
What parents see
Each stage is five questions, and four right completes it. The progress page shows which stages your child has completed in each world and their recent scores; the parent report for the Moonwell story also separates guided practice from independent answers. Everything stays in this browser, with no child account.

Questions parents ask
Are these 3rd grade math games free?
Yes. Every world is free to play now in the browser. Memberships are planned but not open, and the only sign-up is a parent waitlist that asks for a parent email.
Is this a timed multiplication facts drill?
No. There is no countdown. Each fact is shown as equal groups first, so children can work it out, and fluency comes from repeating short stages.
My 3rd grader is still unsure of fractions. Where should they start?
Start Fraction Falls at Grade 2, where shapes use only halves, thirds and fourths, then move to Grade 3 once those feel easy.
Can siblings play together?
Yes. Two-player mode lets two children, or a parent and child, take turns on one device with a shared score.
