20 standards
Operations and Algebraic Thinking
7 standardsM.1.OA.A.1
Solve story problems within 20 about joining, separating and comparing, with the unknown in any spot, using objects, drawings or equations.
M.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.
M.1.OA.B.3
Use properties of addition as shortcuts, like knowing 3 + 8 from 8 + 3, or adding 2 + 6 + 4 by making a ten with 6 + 4 first.
M.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.
M.1.OA.C.5
Link counting on and spotting amounts at a glance to adding and subtracting, like seeing 8 and 5 on a double ten frame as 10 and 3.
M.1.OA.C.6
Find sums and differences within 20 with objects, drawings or equations and strategies like making a ten, and combine facts within 10 quickly in the head.
M.1.OA.D.7
Explain that the equal sign means both sides have the same value, and decide if equations like 7 = 8 - 1 are true or false.
Number and Operations in Base Ten
6 standardsM.1.NBT.A.1
Count to 120 starting from any number, and read, write and match numerals in that range to groups of objects.
M.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.
M.1.NBT.B.3
Compare two two-digit numbers by looking at their tens and ones, and record the result with words and the symbols >, = and <.
M.1.NBT.C.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.
M.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.
M.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
4 standardsM.1.MD.A.1
Put three objects in order from shortest to longest, and compare two objects by measuring each against a third one.
M.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.
M.1.MD.B.3
Tell and write the time to the hour and half-hour on both clock faces and digital clocks.
M.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.
Geometry
3 standardsM.1.G.A.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.
M.1.G.A.2
Put flat or solid shapes together to build a bigger shape, then use that shape to make new ones, without needing formal shape names.
M.1.G.A.3
Split circles and rectangles into 2 or 4 equal parts, name them halves and fourths, and see that more equal parts means smaller parts.
