Algebraic Reasoning: Patterns and Functions: Children use understanding of patters and graphic organizers to solve logic, classification, geometric and number problems. They understand the = sign and explore inequalities.
Numerical and Proportional Reasoning: Children develop understanding of place value, identifying, and comparing the magnitude and value of digits in 2- and 3- digit numbers. They give change for a dollar using pennies, nickels, dimes, quarters, and half-dollars. They solve problems using 1 and 2-digit numbers and are expected to know their addition and subtraction facts to 18. They build the concept of multiplication and division using models and pictures. They use a variety of manipulative models to represent fractions and mixed numbers, finding equal parts of a set of objects, and adding fractions with like and unlike denominators.
Geometry and Measurement: Children identify acute, right, and obtuse angles, build and describe polygons, work with tessellations, and draw and describe line symmetry. They use coordinate systems to draw and interpret maps, tell time to the minute, and solve elapsed time problems involving calendars and clocks. They estimate and measure length to the nearest inch and centimeter.
Working with Data: Children pose questions and use a variety of ways to collect, sort, record, organize, analyze, and compare data from samples and surveys. They describe data trends using range (least to greatest) and mode (most frequently). They conduct simple probability experiments.
