2nd grade math games
Second grade is the year children move from counting to working with tens and ones: adding and subtracting two-digit numbers, reading three-digit numbers and seeing the first equal groups that lead to multiplication.
Below is what 2nd graders usually learn in math, which Clarendium games match each part at the 2nd grade level, and what your child can try today for free.

What 2nd graders learn in math
Most US schools follow the Common Core standards or a close state version. In 2nd grade that means:
- Adding and subtracting within 100. Fluently, using place value and the link between addition and subtraction, with facts within 20 known from memory by the end of the year.
- Place value to 1,000. Hundreds, tens and ones; counting in 5s, 10s and 100s; comparing three-digit numbers.
- Adding and subtracting within 1,000. Using drawings and place value strategies, not yet always the standard written method.
- Equal groups and arrays. Rows and columns of up to 5 by 5, odd and even numbers, and repeated addition: the groundwork for 3rd grade multiplication.
- Halves, thirds and fourths. Splitting circles and rectangles into equal shares and describing them, the first step toward fractions.
- Measurement, time and money. Inches, feet and centimeters, telling time to five minutes, and solving problems with dollars, quarters, dimes, nickels and pennies.
Which Clarendium games fit 2nd grade
Choose “Grade 2” as the practice level (the button above does this for you) and every world sets its numbers for 2nd grade:
- Number Grove (addition): two-digit addition with totals up to about 90, with hints that split a number into tens and ones.
- Subtraction Shores (subtraction): two-digit subtraction, each answer checked by adding back.
- Multiply Mountain (multiplication): equal groups drawn as rows of counters, from groups of 2 to groups of about 7: arrays and repeated addition before the times tables.
- Fraction Falls (fractions): shapes split into halves, thirds and fourths; your child names how many equal parts are colored.
Not covered yet: place value to 1,000, measurement, time and money. Those are worth practicing with real coins, a clock and a ruler at home.
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.
Memberships and the parent waitlist

Founding families: the first 100 families on the waitlist get 40% off for life when memberships open. Leave a parent or guardian email and we will write once, when memberships open. No ads, and we never ask for a child’s name, email or photo.
Questions parents ask
Are these 2nd grade math games free?
Yes, every world is free to play now. Paid memberships are planned but not open; the parent waitlist is the only sign-up, and it asks for a parent email only.
My child finds 2nd grade math hard. Can they play at an easier level?
Yes. Pick 1st grade or Kindergarten in settings. Practicing confidently a level below is better than guessing at the right one.
How long should a 2nd grader practice?
A stage takes a few minutes. One or two stages a day, most days, is plenty at this age.
Does it use the same methods as school?
The hints use counting on, counting back, tens and ones, and equal groups, the strategies most 2nd grade classrooms teach. It does not follow any one textbook.
