Mixed arithmetic in 3rd grade

Third grade has all four operations available at small numbers, which makes random mixed practice possible for the first time. The useful difficulty is choosing: deciding what a question asks before answering it. Word problems fail here not on arithmetic but on picking an operation from a keyword rather than from the situation.

Third grade belongs to the times tables. Multiplication and division are introduced together, area and arrays give them a picture, and rounding to the nearest ten and hundred begins. It is the highest-leverage year in elementary arithmetic: the tables learned here carry fractions, long multiplication and mental math for the rest of school, and gaps left now surface for years.

3rd graders are expected to work across all four operations at small numbers, deciding which one a problem calls for; after that comes all four operations at small numbers, chosen at random.

Watch for picking an operation from a keyword in a word problem instead of from what is being asked.

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 3rd grader know?

Enough to work across all four operations at small numbers, deciding which one a problem calls for.

Why does my 3rd grader keep getting mixed arithmetic wrong?

Most often: picking an operation from a keyword in a word problem instead of from what is being asked.
