First grade math curriculum for all 50 states is very similar.

Number Sense

1) Count, read, and write whole numbers to 100.

2) Compare and order whole numbers to 100 by using the symbols for less than, equal to, or greater than (<, =, >).

3) Understand numbers,

Example: 9 may be represented as 4 + 5, 6 + 3, 2 + 2 + 2 + 3, 10 − 1, 14 − 5.

4) Count and group object in ones and tens

Example: 4 groups of 10 and 5 equals 45, or 40 + 5.

5) Identify and know the value of coins and different combinations of coins

Example: a Quarter is equal to 2 dimes and a nickel

6) Memorize addition facts (sums to 20) and the corresponding subtraction facts.

Examples:

11 + 9 = 20;  16 + 3 = 19, 15 - 5 = 8, 13 - 4 = 9

7) Count by 2s, 5s, and 10s to 100.

Algebra and Functions

1. Use number sentences to solve problems:

Example: There are 19 students in a classroom. 8 of them left for the playground.  How may students are left in the classroom?

Answer: 19 - 8 = 11; There are 11 students left in the classroom.
 

Measurement and Geometry

1) Compare the length, weight, and volume of two or more objects by using direct comparison or a nonstandard unit.

2) Tell time to the nearest half hour and relate time to events (e.g., before/after, shorter/longer).

3) Identify, describe, and compare triangles, rectangles, squares, and circles, including the faces of three-dimensional objects.

Statistics, Data Analysis, and Probability

1) Sort objects and data by common attributes and describe the categories.

2) Represent and compare data  by using pictures, bar graphs, tally charts, and picture graphs.
Example:  largest, smallest, most often, least often

3) Recognize and extend to a next element in simple repeating patterns (e.g., rhythmic, numeric, color, and shape).
