The resource for Grade 1 focuses on building basic numeracy and spatial skills using nature-based examples.

• Mathematical Skills: Students learn to count, compare, and order numbers up to 99; solve single-step addition and subtraction; and identify basic 2D and 3D shapes.
• Climate Integration: Exercises involve counting animals, plants, and cedar trees. Students practice ordering numbers by helping to clean a school playground of numbered plastic bottles.

Grade 2 introduces more complex operations and relates them directly to environmental challenges.

• Mathematical Skills: This level covers numbers up to 999, place value (hundreds, tens, and ones), and more advanced addition and subtraction word problems.
• Climate Integration: Problems are framed around recycling efforts, such as calculating the total number of cans or plastic bottles collected by different students. It also introduces topics like the impact of synthetic pesticides on soil fertility.

Grade 3 emphasizes how small individual actions can lead to a larger positive impact when multiplied.

• Mathematical Skills: Key topics include doubling and tripling numbers, basic fractions, time duration, and identifying perpendicular lines.
  
• Climate Integration: Students calculate how many plastic bottles are saved if they double or triple their recycling efforts. They also learn about fractions through the variety of trees in a garden (fruit, shade, and flowering trees).

The Grade 4 curriculum focuses on using decimals and larger numbers to track resource use and conservation.

• Mathematical Skills: This level introduces the addition and subtraction of decimals, division by multiples of 10, and advanced multiplication (e.g., three-digit by two-digit numbers).
• Climate Integration: Lessons are centered on “Water Scarcity Awareness” and “Recycling Awareness,” such as calculating the weight of paper recycled over several weeks or the amount of rainwater collected by different roof sizes.

Grade 5 explores the geometry of the natural world and more complex fractional operations.

• Mathematical Skills: Topics include divisors of natural numbers, the diameter and radius of a circle, the perimeter of different shapes, and the addition/subtraction of mixed numbers and fractions.
• Climate Integration: Students study the age rings in a tree trunk cross-section and learn about the dangers of dynamite fishing through fraction-based population loss problems.

The Grade 6 resource uses advanced math to model sustainability solutions and measure environmental areas.

• Mathematical Skills: Focus areas include calculating the area of various shapes (rectangles, squares, parallelograms), working with ratios and quotients, and understanding percentages and bisectors.
• Climate Integration: Problems involve converting metric units for a new forest area, finding the area of a solar panel field, and calculating the percentage of cedar trees in a reforestation project.
