Mathematics
Represent and interpret data.
Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot where the horizontal scale is marked off in appropriate units – whole numbers, halves, or quarters.

Know ordinal names and counting flexibility.
Use ordinal numbers correctly when identifying object position (e.g., first, second, third, etc.).

Number Sense: Understand and apply numbers, ways of representing numbers, and the relationships among numbers and different number systems.
Express whole numbers, fractions, decimals, and percents using and connecting multiple representations.
Reason with shapes and their attributes.
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.
Measurement: Understand and apply appropriate units of measure, measurement techniques, and formulas to determine measurements.
Solve problems involving perimeter of 2-dimensional figures and area of rectangles.
Use place value understanding and properties of operations to add and subtract.
Add up to four two-digit numbers using strategies based on place value and properties of operations.
Work with time and money.
Read a calendar distinguishing yesterday, today and tomorrow. Read and write a date.
Reason with shapes and their attributes.
Partition circles and rectangles into two and four equal shares; describe the shares using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

Perform operations with multi-digit whole numbers and with decimals to hundredths.
Fluently multiply multi-digit whole numbers using the standard algorithm.
Identify and continue patterns.
Identify, continue and label patterns (e.g., aabb, abab). Create patterns using number, shape, size, rhythm or color.
Use place value understanding and properties of operations to add and subtract.
Add within 100, including adding a two-digit number and a one-digit number and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method, and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
Add and subtract within 20.
Fluently add and subtract within 20 using mental strategies. (See standard 6, Grade 1, for a list of mental strategies.) By end of Grade 2, know from memory all sums of two one-digit numbers.
Use place value understanding and properties of operations to add and subtract.
Add and subtract within 1000 using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

Use ratios and unit rates to model, describe and extend problems in context.
Shapes can be described by defining attributes and created by composing and decomposing. Students can:
Distinguish between defining attributes versus non-defining attributes. (CCSS: 1.G.1)
