In Grade 2, instructional time ought to concentrate on four basic territories: (1) expanding comprehension of base-ten documentation; (2) building familiarity with expansion and subtraction; (3) utilizing standard units of measure; and (4) depicting and breaking down shapes.
Students portray and break down shapes by looking at their sides and edges. Understudies examine, depict, and reason about breaking down and joining shapes to make different shapes. Through building, drawing, and dissecting two-and three-dimensional shapes, understudies add to an establishment for comprehension region, volume, compatibility, closeness, and symmetry in later evaluations.
Students utilize their comprehension of expansion to create familiarity with expansion and subtraction inside of 100. They take care of issues inside of 1000 by applying their comprehension of models for expansion and subtraction, and they create, talk about, and use effective, precise, and generalizable techniques to process totals and contrasts of entire numbers in base-ten documentation, utilizing their comprehension of spot worth and the properties of operations. They select and precisely apply systems that are proper for the connection and the numbers included to rationally ascertain totals and contrasts for numbers with just tens or just hundreds.
Students perceive the requirement for standard units of measure (centimeter and inch) and they utilize rulers and other estimation apparatuses with the understanding that direct measure includes a cycle of units. They perceive that the littler the unit, the more emphasess they have to cover a given length.

Students augment their comprehension of the base-ten framework. This incorporates thoughts of tallying in fives, tens, and products of hundreds, tens, and ones, and in addition number connections including these units, including looking at. Understudies comprehend multi-digit numbers (up to 1000) written in base-ten documentation, perceiving that the digits in every spot speak to measures of thousands, hundreds, tens, or ones (e.g., 853 is 8 hundreds + 5 tens + 3 ones).
