15 standards

Number Sense

4 standards
1.NS.1
Count to 120 or more by ones, fives and tens starting at any number, and read, write and use numerals in that range to show how many objects there are.
1.NS.2
Show what the digits of two-digit numbers mean with objects and drawings, including multiples of 10 and other ways to make a number, like 34 as 2 tens and 14 ones.
1.NS.3
Use order words like first, second and third to name the position of items in a line of up to 20.
1.NS.4
Compare two-digit numbers by looking at their tens and then their ones, and record the result with >, = or <, like 52 > 48.

Computation and Algebraic Thinking

4 standards
1.CA.1
Add and subtract within 20 quickly using strategies like counting on, making ten, fact families and doubles plus one, and model what 0 and the equal sign mean.
1.CA.2
Solve story problems within 20 that add to, take from, join, separate or compare, with the unknown in any spot, using objects, drawings or equations like 9 + ? = 15.
1.CA.3
Add within 100 using place value, models and drawings, like 46 + 7 or 46 + 30, and explain the strategy and the thinking behind it.
1.CA.4
Make and continue number patterns that grow by adding, staying within 100, and state the rule, like 5, 15, 25, 35 adds 10 each time.

Geometry

3 standards
1.G.1
Sort the features that define a shape, like a triangle's three sides, from ones that do not matter, like color or size, and draw shapes with the defining features.
1.G.2
Put flat or solid shapes together, like squares and half-circles or cubes and cones, to make a bigger shape, then use that shape to build new ones.
1.G.3
Split circles and rectangles into halves and fourths, call the whole two halves or four quarters, and notice that cutting into more equal parts makes each part smaller.

Measurement

3 standards
1.M.1
Line up objects from least to most by length, area, capacity, weight or temperature, by comparing them directly or with a nonstandard unit like paper clips.
1.M.2
Tell and write time to the half hour on analog clocks, connect times to events like before and after, and explain how a digital clock shows hours and minutes.
1.M.3
Name what a penny, nickel and dime are worth and find the total of a handful of them, like 1 dime and 2 nickels make 20 cents.

Data Analysis

1 standard
1.DA.1
With help, run a class survey, show the results in bar graphs, picture graphs or tables where each mark counts as one, and draw conclusions by comparing.
