Mathematics — Grade 3
Goal 1
- Objective 1.01
- Develop number sense for whole numbers through 9,999.
- Connect model, number word, and number using a variety of representations.
- Build understanding of place value (ones through thousands).
- Compare and order.
- Find related resources
- Objective 1.02
- Develop fluency with multi-digit addition and subtraction through 9,999 using:
- Strategies for adding and subtracting numbers.
- Estimation of sums and differences in appropriate situations.
- Relationships between operations.
- Find related resources
- Objective 1.03
- Develop fluency with multiplication from 1x1 to 12x12 and division up to two-digit by one-digit numbers using:
- Strategies for multiplying and dividing numbers.
- Estimation of products and quotients in appropriate situations.
- Relationships between operations.
- Find related resources
- Objective 1.04
- Use basic properties (identity, commutative, associative, order of operations) for addition, subtraction, multiplication, and division.
- Find related resources
- Objective 1.05
- Use area or region models and set models of fractions to explore part-whole relationships.
- Represent fractions concretely and symbolically (halves, fourths, thirds, sixths, eighths).
- Compare and order fractions (halves, fourths, thirds, sixths, eighths) using models and benchmark numbers (zero, one-half, one); describe comparisons.
- Model and describe common equivalents, especially relationships among halves, fourths, and eighths, and thirds and sixths.
- Understand that the fractional relationships that occur between zero and one also occur between every two consecutive whole numbers.
- Understand and use mixed numbers and their equivalent fraction forms.
- Find related resources
- Objective 1.06
- Develop flexibility in solving problems by selecting strategies and using mental computation, estimation, calculators or computers, and paper and pencil.
- Find related resources
