What should a 2nd grader know in math?

By the end of grade 2: place value to 1,000, skip counting, fluent facts within 20, and 2-digit adding and subtracting with regrouping. Also arrays, time to 5 minutes, counting coins, measuring length and naming shapes.

How long does the 2nd grade math test take?

Usually 15 to 20 minutes and 18 to 28 questions. It asks more questions only where an answer is unclear, so a child who is secure finishes faster.

Is this a real assessment?

It is a screening check, not a formal test. It shows which topics are secure and where to look. The levels test for each topic then finds the exact step to practice.

Can my child use paper, fingers or a calculator?

Paper and pencil are fine for 2-digit sums. A calculator is not. Facts within 20 should be quick by the end of grade 2, so the check times them quietly.

What if my child is not in grade 2 yet?

Use it at the end of grade 1 to see what is coming, or in grade 3 to check the grade 2 basics. If most topics come back as gaps, the report suggests the grade 1 check-up.

Is my child’s data saved or shared?

What the check-up covers

The check-up follows what most US schools teach in grade 2 (Common Core 2.OA, 2.NBT, 2.MD and 2.G). It has 9 topics. Each one has a grade 2 target and, for most, a few earlier steps that lead up to it.

Topic	Grade 2 target	Earlier steps it checks if needed
Place value to 1,000	Comparing, expanded form, 10 and 100 more	Tens and ones → Hundreds, tens and ones
Skip counting, even and odd	Skip counting, even and odd	Counting to 120
Addition	2-digit addition with regrouping	Addition facts within 20 → Adding tens
Subtraction	2-digit subtraction with regrouping	Subtraction facts within 20 → Subtracting tens
Equal groups and arrays	Arrays and repeated addition	Equal groups
Telling time	Time to 5 minutes, a.m. and p.m.	Time to the hour and half hour
Money	Making change	Counting coins
Measuring length	Measuring with a ruler	–
Shapes	Sides and corners	Naming shapes

How it works

Every topic starts with two questions at the grade 2 target. Two right answers mean the topic is solid, and the check moves on. One right answer brings a third question.

If the target is missed, the check steps down to the skill before it. If needed it steps down once more, until it finds what your child can already do. That is where practice should start.

A wrong answer is never wasted. Common mistakes, like forgetting to regroup, subtracting the smaller digit from the bigger one, or reading the hour hand too early, are named in the report.

Fact answers are also timed quietly. A fact answered correctly after a long pause is still being worked out, not remembered, and the report says so.

How to read the report

Solid (green): your child got both grade 2 questions right. Keep it fresh with a little mixed practice.
Shaky (yellow): two out of three right. Your child mostly has it; a week of short practice usually makes it solid.
Gap (red): the grade 2 target is not there yet. The report shows the step your child can already do and the next lesson to work on.

The report starts with one line: Start here. It is the first topic, in the usual teaching order, that is not yet solid. Work on that one first, because later topics often build on it.

You can print the report. It is also saved in this browser, so you can compare after a few weeks.

Tips for a fair result

Choose a calm time, and let your child read the questions. The Read to me button reads them aloud.
Don’t help or give hints. If your child is stuck, Skip is the right answer.
If your child gets tired, take a break. Two short sittings are better than one rushed one.

After the check-up

Open the lesson linked for each gap and read it together first. Each lesson has a parent script, worked examples and a short quiz. Then use the topic’s levels test to confirm the step, and the worksheet for practice on paper.

Take the check-up again in three or four weeks. Gaps that turn into solid topics are the clearest sign that practice is working. For a whole-grade overview, see 2nd grade math. For printable practice, use the worksheets and the math test generator.

Which grade’s check-up to choose

Pick the grade your child is in now, or has just finished. Early in the school year, the grade just finished is often the better choice. The new grade’s topics haven’t been taught yet. If most topics come back as gaps, try the 1st grade check-up; if every topic is solid, try the 3rd grade check-up. All grades are on the math check-up page.

Topic quizzes and levels

Every topic in the check-up has its own levels page. It is a ladder of short tests from the first step to the grade target: place value, number sense, addition, subtraction, multiplication, measurement and geometry. Use them after the check-up to pin down the exact step.

More grade 2 practice on paper

Each topic has a printable worksheet with an answer key. Try hundreds, tens and ones, skip counting, 2-digit addition with regrouping, 2-digit subtraction with regrouping, multiplication arrays, telling time, counting coins, measuring length and 2D shapes.

For a month of daily practice on paper, the Grade 2 Math in 30 Days workbook has one page a day, tip sheets, start and finish tests and an answer key. A free sample is on the same page.

For teachers and tutors

Use the check-up at the start of the year or before a tutoring block. Each child takes it on their own device and prints or shows you the report. Nothing needs a login, and no student data leaves the device.
