❏ 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)

**Important**

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

❏ I can use repeated addition to identify up to 25 objects in an array and write an equation

to express the total. (OA.4)

❏ I can add up to four two-digit numbers. (NBT.6)

❏ I can mentally add and subtract 10 and 100 from any number 100-900. (NBT.8)

❏ I can use place value, properties, or drawings to explain why addition and subtraction

strategies work. (NBT.9)

4) Solve one step word problems within 100

**Essential**

❏ I can solve word problems within 100 with unknowns in all positions. (OA.1)

**Important**

❏ I can use drawings and symbols involving lengths of the same units to solve addition

and subtraction word problems within 100. (MD.5)

❏ I can solve word problems involving money, using $ and¢symbols. (MD.8)

5) Measure an object using standard units

**Essential**

❏ I can use standard tools to measure length. (MD.1)

❏ I can measure the length of an object using two different units. (MD.2)

**Important**

❏ I can estimate lengths using inches, feet, centimeters, and meters. (MD.3)

**Nice to Know**

❏ I can measure to figure out how much longer one object is than another. (MD.4)

❏ I can display and analyze measurement data. (MD.9)

6) Tell and write time from analog and digital clocks to the nearest 5 minutes, using a.m. and

p.m.

**Essential**

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

**Note:**

**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

intervention.

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

as part of Tier 1 instruction.
