Standards
Mathmatical Reasoning -4th grade
1.0 Students make decisions about how to approach problems:
1.1 Analyze problems by identifying relationships,
distinguishing relevant from irrelevant information, sequencing
and prioritizing information, and observing patterns.
1.2 Determine when and how to break a problem into simpler parts.
2.0 Students use strategies, skills, and concepts in finding solutions:
2.1 Use estimation to verify the reasonableness
of calculated results.
2.2 Apply strategies and results from simpler problems to more
complex problems.
2.3 Use a variety of methods, such as words, numbers, symbols,
charts, graphs, tables, diagrams, and models, to explain mathematical
reasoning.
2.4 Express the solution clearly and logically by using the appropriate
mathematical notation and terms and clear language; support solutions
with evidence in both verbal and symbolic work.
2.5 Indicate the relative advantages of exact and approximate
solutions to problems and give answers to a specified degree of
accuracy.
2.6 Make precise calculations and check the validity of the results
from the context of the problem.
Number Sense
3.0 Students solve problems involving addition, subtraction, multiplication, and division of whole numbers and understand the relationships among the operations:
3.1 Demonstrate an understanding of, and the ability to use, standard algorithms for the addition and subtraction of multi digit numbers.3.2 Demonstrate an understanding of, and the ability to use, standard algorithms for multiplying a multi digit number by a two-digit number and for dividing a multi digit number by a one-digit number; use relationships between them to simplify computations and to check results.
3.3 Solve problems involving multiplication of multi digit numbers by two-digit numbers.
MATH
4.1 Students demonstrate an understanding of the physical and human geographic features that define places and regions in California.
- Explain and use the coordinate grid system of latitude and longitude to determine the absolute locations of places in California and on Earth.
- Identify the state capital and describe the various regions of California, including how their characteristics and physical environments (e.g., water, landforms, vegetation, climate) affect human activity.
- Identify the locations of the Pacific Ocean, rivers, valleys, and mountain passes and explain their effects on the growth of towns.
- Use maps, charts, and pictures to describe how communities in California vary in land use, vegetation, wildlife, climate, population density, architecture, services, and transportation.
