22 standards
Operations and Algebraic Thinking
8 standards1.OA.A.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.A.2
Solve word problems that add three numbers with a total of 20 or less, like 4 + 6 + 3 = 13, with objects, drawings or an equation.
1.OA.B.3
Use the order and grouping properties to add and subtract more easily, like knowing 3 + 8 = 11 because 8 + 3 = 11.
1.OA.B.4
Turn a subtraction problem into a missing-number addition, like finding 10 - 8 by asking what added to 8 makes 10.
1.OA.C.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.C.6
Add and subtract within 20 using mental strategies like counting on, making ten or doubles plus one, and be fluent with facts within 10.
1.OA.D.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.D.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 standards1.NBT.A.1
Count to 120 starting from any number, and read, write and match numerals in that range to groups of objects.
1.NBT.B.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.B.3
Compare two two-digit numbers by looking at their tens first, then their ones, and record the answer with >, = or <.
1.NBT.C.4
Add within 100, like 47 + 6 or 47 + 30, with models or drawings, adding tens to tens and ones to ones, making a ten when needed, and explain it in writing.
1.NBT.C.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.C.6
Subtract tens from tens within 90, like 70 - 30 = 40, using models, drawings or place value, and explain the thinking.
Measurement and Data
5 standards1.MD.A.1
Put three objects in order from shortest to longest, and compare two objects by measuring each against a third one.
1.MD.A.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.B.3
Tell and write the time to the hour and half-hour on both clock faces and digital clocks.
1.MD.C.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.D.5
Find the total value of a set of coins worth up to 50 cents when all the coins are one kind, like 3 dimes or 6 nickels.
Geometry
3 standards1.G.A.1
Tell the features that make a shape what it is, like three sides, from ones that do not, like color or size, and build and draw shapes with those features.
1.G.A.2
Put together flat shapes like squares, triangles and half-circles, or solids like cubes, cones and cylinders, to make a new shape, then build more shapes from it.
1.G.A.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.
