In Grade 2, instructional time should focus on four critical areas: (1) extending understanding of base-ten notation; (2) building fluency with addition and subtraction; (3) using standard units of measure; and (4) describing and analyzing shapes.

Students extend their understanding of the base-ten system. This includes ideas of counting in fives, tens, and multiples of hundreds, tens, and ones, as well as number relationships involving these units, including comparing.

• Students use their understanding of addition to develop fluency with addition and subtraction within 100.
• Students recognize the need for standard units of measure (centimeter and inch) and they use rulers and other measurement tools with the understanding that linear measure involves an iteration of units.
• Students describe and analyze shapes by examining their sides and angles.

This printable worksheet includes 50 math puzzles especially designed for Grade 2, with their answers at the end.
