27 standards

Operations and Algebraic Thinking

5 standards
2.1
Solve one- and two-step story problems by adding or subtracting within 100, showing the problem with a drawing or an equation that uses a box for the missing number.
2.2
Add and subtract within 20 quickly with mental strategies like counting on, making ten or related facts, and recall every sum of two one-digit numbers from memory.
2.3
Pair up objects to tell whether a group of up to 20 is even or odd, and write each even number as a double, like 12 = 6 + 6.
2.4
Find the total in a rectangular array of up to 5 rows and 5 columns with objects, pictures and repeated addition, and write it as a sum, like 4 + 4 + 4 = 12.
2.5
Copy, continue, make up and describe patterns and number sequences with different materials, like skip counting by 5s on a hundreds chart.

Operations with Numbers: Base Ten

9 standards
2.6
Explain that a three-digit number shows hundreds, tens and ones, with 100 as a bundle of ten tens and 100, 200 and so on to 900 as whole hundreds.
2.7
Skip count up to 1000 by 1s, 5s, 10s and 100s, like 135, 140, 145 or 300, 400, 500.
2.8
Read and write numbers to 1000 as digits, in words, and in expanded form, like 426 as 400 + 20 + 6.
Common Core 2.NBT.3
2.9
Compare two three-digit numbers digit by digit from the hundreds down, like 482 is more than 428, recording it with >, = or < and in words.
2.10
Add and subtract within 100 quickly and accurately, using place value and the link between addition and subtraction.
Common Core 2.NBT.5
2.11
Find the sum of as many as four two-digit numbers with a choice of strategies, like 23 + 18 + 37 + 12.
2.12
Add and subtract within 1000 with models, drawings and place value, combining hundreds, tens and ones separately, regrouping as needed, and linking it to written steps.
2.13
Add or subtract 10 or 100 mentally from any number between 100 and 900, like 365 + 100 = 465.
2.14
Explain why an adding or subtracting strategy works, not just that it gets the right answer.
Common Core 2.NBT.9

Data Analysis

2 standards
2.15
Measure several objects to the nearest whole unit and show their lengths on a line plot marked in whole units.
2.16
Make picture and bar graphs of data with up to four groups, solve put-together, take-apart and compare problems from a bar graph, and predict outcomes from charts.

Measurement

8 standards
2.17
Pick a fitting tool, like a ruler, yardstick, meter stick or measuring tape, and use its standard units to measure how long an object is.
2.18
Measure the same object in two units, like inches and feet, and explain why the smaller unit gives the bigger number.
2.19
Estimate lengths in inches, feet, centimeters and meters, like guessing a desk is about 2 feet long.
2.20
Measure two objects to find how much longer one is than the other, giving the difference in standard units, like 4 inches longer.
2.21
Solve story problems about lengths in the same unit by adding or subtracting within 100, shown with drawings like a ruler or an equation with a missing number.
2.22
Draw a number line with whole numbers and use it to show sums and differences within 100, like hopping from 35 forward 20 to land on 55.
2.23
Tell and write the time to the nearest five minutes on both clock faces and digital clocks, with a.m. and p.m.
Common Core 2.MD.7
2.24
Solve money problems, naming nickels and quarters and their values, counting mixed coins, and adding or subtracting within a dollar using $ and ¢ but no decimals.

Geometry

3 standards
2.25
Name triangles, quadrilaterals, pentagons, hexagons and cubes, and recognize and draw shapes with given features, like a shape with five angles.
2.26
Divide a rectangle into rows and columns of equal squares and count them to find the total, like 3 rows of 4 make 12.
2.27
Cut circles and rectangles into 2, 3 or 4 equal shares called halves, thirds or fourths, see the whole as all its shares, and know equal shares of one whole can look different.
