1. FIRST GRADE ADDITION Keri Haws

2. First Grade Mathematics Rubric Number Sequence and Operations Identifies numbers 0-100 Writes numbers 0-100 Understands place value Counts by 2's to 100 Counts by 5's to 100 Counts by 10's, forward and backward to 100 Solves addition problems up to 20 Solves subtraction problems from 20 or less

3. Addition Combination of 2 or more different groups of numbers added together Example: If you have two apples in one pile, and two apples in a different pile, you have four apples total + = 2 2 4

4. How many ducks are in the zoo all together? + = 2 3 5 There are 5 ducks total in the zoo

5. Subtraction Combination of two or more different groups that are subtracted from one another Example: You have 3 bananas and eat two. How many bananas are left? - = 3 2 1

6. There are four rabbits and one hops away. How many are left? - = 4 1 3 There are 3 rabbits left
