This educational guide focuses on key concepts of rational numbers and geometric reasoning for 7th graders. Students will learn to convert between fractions, decimals, whole numbers, and percentages effectively. It also covers representing squares and square roots geometrically, solving problems with addition, subtraction, multiplication, and division involving fractions and decimals. Additionally, students will explore proportional relationships and develop skills in generating formulas for conversions and area, as well as classifying shapes using geometric vocabulary.

Transcription de la présentation

  1. (7.1) Number, operation, and quantitative reasoning. The student represents and uses rational numbers in a variety of equivalent forms. The student is expected to: (B) convert between fractions, decimals, whole numbers, and percents mentally, on paper, or with a calculator.

  2. (7.1) Number, operation, and quantitative reasoning. The student represents and uses rational numbers in a variety of equivalent forms. The student is expected to: (C) represent squares and square roots using geometric models.

  3. (7.2) Number, operation, and quantitative reasoning. The student adds, subtracts, multiplies or divides to solve problems and justify solutions. The student is expected to: (B) use addition, subtraction, multiplication, and division to solve problems involving fractions and decimals.

  4. (7.3) Patterns, relationships, and algebraic thinking. The student solves problems involving proportional relationships. The student is expected to: (B) estimate and find solutions to application problems involving proportional relationships such as similarity, scaling, unit costs, and related measurement units.

  5. (7.4) Patterns, relationships, and algebraic thinking. The student represents a relationship in numerical, geometric, verbal, and symbolic form. • The student is expected to: • generate formulas involving conversions, perimeter, area, circumference, volume, and scaling. • graph data to demonstrate relationships in familiar concepts such as conversion, perimeter, area, circumference, volume, and scaling.

  6. (7.6) Geometry and spatial reasoning. The student compares and classifies shapes and solids using geometric vocabulary and properties. • The student is expected to: • use angle measurements to classify pairs of angles as complementary or supplementary.
