Standards for Mathematical Practice

8 standards
1.SMP.1
Work out what an addition or subtraction story problem is asking and stick with it, like finding how many more cookies one child has within 20.
1.SMP.2
Move between a story and a number sentence, like writing 8 + ? = 13 for a problem about birds and telling what the missing number means.
1.SMP.3
Explain a strategy for adding or subtracting within 20 with objects or drawings, and decide whether a classmate's method works.
1.SMP.4
Represent everyday situations with drawings, ten frames or equations, like showing 6 + 7 for the crayons in two boxes.
1.SMP.5
Choose tools such as base ten blocks, a hundred chart, a number line or coins to solve first grade problems and check answers.
1.SMP.6
Use the equal sign correctly and count, measure and tell time with care, like knowing 7 = 7 is true and reading a clock to the half hour.
1.SMP.7
Use how numbers are built from tens and ones, like seeing 8 + 6 as 8 + 2 + 4 to make a ten first.
1.SMP.8
Notice results that repeat while adding and subtracting, like seeing that adding 10 to a number changes only its tens digit.

Operations and Algebraic Thinking

8 standards
1.OA.1
Solve addition and subtraction word problems within 20, about joining, taking away and comparing, with the unknown in any spot, like 7 + ? = 12.
1.OA.2
Solve word problems that add three whole numbers with a total of 20 or less, using objects, drawings or an equation with a box for the missing number.
1.OA.3
Use the rules of adding to make problems easier, like knowing 8 + 3 = 11 means 3 + 8 = 11, or adding 6 + 4 first to make a ten in 2 + 6 + 4.
1.OA.4
Turn a subtraction problem into a missing-number addition, like finding 10 - 8 by asking what added to 8 makes 10.
1.OA.5
Use counting to add and subtract, like counting on two more to add 2 or counting back two to take away 2.
1.OA.6
Add and subtract within 20 with strategies like counting on and making ten, like 8 + 6 = 8 + 2 + 4, and know the facts within 10 quickly and accurately.
1.OA.7
Know that the equal sign means both sides are the same amount, and tell whether equations like 7 = 8 - 1 or 4 + 1 = 5 + 2 are true or false.
1.OA.8
Find the missing number in an addition or subtraction equation with three numbers, like 8 + ? = 11 or 5 = ? - 3.

Number and Operations in Base Ten

6 standards
1.NBT.1
Count to 120 starting from any number, and read, write and match numerals in that range to groups of objects.
1.NBT.2
Know that a two-digit number is made of tens and ones, like 10 is a bundle of ten ones, 14 is a ten and four ones, and 70 is seven tens.
1.NBT.3
Compare two two-digit numbers by looking at their tens first, then their ones, and record the answer with >, = or <.
1.NBT.4
Add within 100 with models and drawings, like 34 + 8 or 34 + 20, adding tens to tens and ones to ones, making a new ten when needed, and explain the steps.
1.NBT.5
Find 10 more or 10 less than any two-digit number in their head, like 47 + 10 = 57, without counting, and explain how they know.
1.NBT.6
Subtract tens from tens within 90, like 70 - 30 = 40, using models, drawings or place value, and explain the thinking.

Measurement and Data

10 standards
1.MD.1
Put three objects in order from shortest to longest, and compare two objects by measuring each against a third one.
1.MD.2
Measure how long an object is by laying same-size units end to end with no gaps or overlaps, and give the length as a whole number, like 6 paper clips long.
1.MD.3a
Tell and write the time to the hour and half-hour on both clock faces and digital clocks.
1.MD.3b
Name the days of the week and know that every week has seven days.
1.MD.3c
Name the months of the year, know a year has 12 months, and know how many weeks make up a month.
1.MD.4
Sort data into up to three groups, show it in a chart or picture, and answer how many in all, how many in each group, and how many more or fewer.
1.MD.5a
Tell the value of each U.S. coin from the penny to the dollar coin, and write amounts with cent and dollar signs, like 10¢ or $1.
1.MD.5b
Compare the worth of U.S. coins, like knowing a quarter is worth more than a dime.
1.MD.5c
Count groups of the same kind of coin up to one dollar, like counting 7 dimes as 70 cents.
1.MD.5d
Show the value of a larger coin with smaller coins of one kind, like 5 nickels for a quarter or 10 pennies for a dime.

Geometry

3 standards
1.G.1
Tell the features that make a shape what it is, like a triangle has three sides, from ones that do not, like color or size, and build and draw shapes to match.
1.G.2
Put shapes together, like two triangles into a square or cubes into a tower, to make a new shape, and build again from the new shape.
1.G.3
Split circles and rectangles into two or four equal shares, call them halves, fourths or quarters, and know that more shares means smaller shares.
