Grade 2 Math · Regrouping
Build Grade 2 math skills with five 10-question practice tests covering regrouping in addition and subtraction, place value, and word problems.
These Grade 2 Math practice tests help students regroup when adding or subtracting two-digit numbers. Students practice exchanging 10 ones for 1 ten, trading 1 ten for 10 ones, and explaining why the value stays the same.
Complete one 10-question test at a time. Use base-ten blocks or quick drawings to show the exchange between tens and ones. Ask the student to explain why regrouping changes the form of a number but not its total value.

Regrouping changes a number into equivalent place-value groups, such as trading 10 ones for 1 ten or 1 ten for 10 ones.
In addition, regrouping is used when the ones total is 10 or more. Ten ones become one additional ten.
