Addition Subtraction Mental Math

Mixed arithmetic in 2nd grade

Early mental math is less about arithmetic than about number sense — knowing that 7 and 3 make 10, that 20 is two tens, that adding and subtracting undo each other. Those relationships are what let a child calculate rather than count, and they are built by frequent short practice rather than by longer sessions.

Second grade is the written-method year. Column addition and subtraction arrive, then regrouping, and with them the first arithmetic that has a procedure to follow rather than a fact to recall. Children who still lack instant facts within 20 find this year disproportionately hard, because they are running a procedure and reconstructing facts at the same time.

2nd graders are expected to mix addition and subtraction within 100 and choose the right operation for a problem; after that comes mixed addition and subtraction within 100.

Watch for reading the sign too quickly and adding when the problem says subtract.

Frequently Asked Questions

Is mixed practice better than practising one operation at a time?

Both have a use. Practising one operation builds the facts; mixing them builds the habit of reading the problem before answering, which is what breaks down in word problems and on tests. Use single-operation practice to fix a gap and mixed practice to keep it.

What mixed arithmetic should a 2nd grader know?

Enough to mix addition and subtraction within 100 and choose the right operation for a problem.

Why does my 2nd grader keep getting mixed arithmetic wrong?

Most often: reading the sign too quickly and adding when the problem says subtract.
