❏ I can use place value strategies and number properties to fluently add and subtract

within 100. (NBT.5)

❏ I can use objects, drawings, and written methods to add and subtract numbers within

1,000. (NBT.7)


❏ I can tell if a group of objects (up to 20) has an odd or even number of members. (OA.3)

❏ I can tell and write time to the nearest 5 minutes. (MD.7)


The following Core Standards do not connect directly to the BELS but should be introduced/integrated

in 2nd grade math as part of measurement, data, and geometry.

Nice to Know

❏ I can show data on a picture graph and a bar graph. (MD.10)

❏ I can analyze data in a bar graph. (MD.10)

❏ I can recognize and draw shapes based on attributes. (G.1)

❏ I can divide rectangles into rows and columns of same-size squares. (G.2)

❏ I can divide circles and rectangles into two, three, and four equal parts and name those

parts. (G.3)

BELS-(Essential Standards): These standards are the main curricular focus of the grade.

Tier 1 instructional time is spent on these standards to ensure all students are proficient on

these standards. Common Formative and Summative assessments are administered to

determine which students need interventions or enrichments.

Important Standards: These standards support or extend the BELS. Tier 1 instruction time

is spent to ensure understanding. Student learning is assessed; but will not be a focus of


Nice to Know Standards: These standards are introduced and integrated during the grade

as part of Tier 1 instruction.
