Lessons are organized into chapters that introduce and cover:
- Number Sense - Second grade "Number Sense" teaches how to read, compare, match, and define whole numbers. Lessons also cover skip counting, odd and even numbers, number line use, and rounding.
- Fractions - Second grade "Fractions" teaches the difference between equal and unequal parts. Fractions divided by halves, thirds, fourths, and eights are introduced in lessons such as "Mangos Take Out", which you can see a screenshot of, below.
- Operations - Second grade "Operations" starts with math vocabulary. It distinguishes the difference between addition and subtraction facts up to 18, and teaches second graders about the associative property. Lessons move into addition and subtraction of one and two digit numbers and gives problem solving strategy using regrouping. This chapter ends with lessons on multiplication, division, and estimation.
- Money - Second grade "Money" teaches about coin values, how to count money, and how to add and subtract it using regrouping.
- Patterns - Second grade "Patterns" teaches students how to identify, sort and classify things by common patterns or attributes. Students learn to identify patterns on a "hundreds chart" and then apply those patterns to skip counting by 2s, 5s, and 10s as well as patterns such as tessellation.
- Algebra - Second grade "Algebra" introduces students to algebraic symbols and the commutative property of addition. Lessons also teach number sentences, equal vs. unequal, greater than vs. less than, real world equations, and solving for unknown numbers.
- Geometry - Second grade "Geometry" teaches about two and three-dimensional shapes. Lessons cover straight vs. curved lines, open vs. closed shapes, and planes vs. solid objects. Students are introduced to similar, congruent, parallel, and perpendicular shapes and asked to compare them in the lessons.
- Positions - Second grade "Positions" introduces basic geometry and spatial relationships. Students learn how to identify, locate and move objects according to directional (left, right, up, down) and positional (top, middle, inside) instruction. Second graders use the coordinate grid as well as the number line to plot and identify numbers.
- Using Shapes - Second grade "Shapes" teaches congruent shapes and symmetry. Students learn to match congruent shapes and identify lines of symmetry in two dimensional shapes. Students are also taught how to identify and create vertical and horizontal lines of symmetry.
- Spatial Sense - Second grade "Spatial Sense" teaches how to build and calculate perimeter and area of two dimensional shapes. It teaches how to recognize geometric shapes and how to use one shape to build another. This chapter also teaches the concepts of perimeter and area.
- Time - Second grade "Time" introduces different ways that time is classified, such as calendar time and clock time. Students learn about digital vs. analog time telling as well as the relationship of hours, days, weeks, and months.
- Length - Second grade "Length" teaches how to use, compare and measure length. Students will choose the appropriate tool and use it to measure different metrics. Students will also apply the measurement skills to measure for perimeter as well as use metric units to determine length.
- Weight - Second grade "Weight" teaches different attributes of weight. Students will estimate, compare and measure with customary and non-customary units of measure.
- Capacity - Second grade "Capacity" teaches how to measure, compare and estimate capacity. It shows students how to identify the best unit and will ask them to place objects in order according to capacity.
- Temperature - Second grade "Temperature" teaches how to measure temperatures. Lessons introduce Fahrenheit and Celsius and show students how to read a thermometer and compare different readings.
- Graphing - Second grade "Graphing" reinforces the "Patterns" chapter by asking students to sort objects. They then learn to create a tally table and record information in pictographs and bar graphs.
- Using Data - Second grade "Using Data" teaches the basics of statistics, showing students how to compare and make predictions based on the data that they organized into graphs.
- Probability - Second grade "Probability" teaches the basics of probability. It teaches the difference between principles of certainty, impossibility, likely and least likely. Second graders are prompted to identify the differences and make predictions based on data.
- Patterns in Nature -Students will learn the steps in the life cycle, the food chain, pond habitat, wetland habitat, and ocean habitat. Lessons will focus on the different characteristics of the different types of animals in each habitat.
- Force and Motion - Students learn about magnetism and the law of magnetic attraction, and apply these to real life objects.
- Earth and Space - Students learn about the objects in our sky, their orbits, and their characteristics.
- Wants and Needs - Students learn about the basic human needs of food, clothing, and shelter and how these needs are met.
- Earth Science - Students learn about using maps to locate the United States as well as individual states. Map symbols, use of globes, and cardinal directions are taught.
- Contributions to Science - Students learn about historic places, the symbols, icons, buildings, and holidays that represent American beliefs and principles.
- The Surface of the Earth - Students learn about the different types of jobs in the home, school, and community.
