Identify and give the value of different coins. Select standard and non-standard tools for determining length, time, temperature, weight, and capacity, and use them to solve every day problems. Solve and justify solutions to real-life problems involving the measurement of time, length, area, perimeter, weight, temperature, mass, capacity, and volume. Select measuring tools and units of measurement that are appropriate for what is being measured. Explain the answer.
Relationships are central to mathematical understanding.
A study of patterns often reveals regularity, indicating the presence of a mathematical relationship. Studying relationships allows students to make generalizations and predictions about phenomena and occurrences. Recognize, describe, extend, copy, and create a wide variety of patterns. Explore the use of variables and open sentences to describe relationships. Represent and describe both geometric and numeric relationships.
