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).
