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.

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 math should a 2nd grader know by the end of the year?

Column addition and subtraction with two-digit numbers including regrouping, instant facts within 20, place value to the hundreds, and the beginnings of skip counting towards multiplication.
