• Ramsey Junior High Math



    In Grade 7, instructional time should focus on four critical areas:

    Developing understanding of and applying proportional relationships

    Students extend their understanding of ratios and develop understanding of proportionality to solve single- and multi-step problems including those involving discounts, interest, taxes, tips, and percent increase or decrease.  Students solve problems about scale drawings, graph proportional relationships, and understand the unit rate informally as slope.

    Developing understanding of operations with rational numbers and working with expressions and linear equations

    Students develop an understanding of number, recognizing fractions, decimals, and percents as different representations of rational numbers. Students extend addition, subtraction, multiplication, and division to all rational numbers.  Students interpret the rules for adding, subtracting, multiplying, and dividing with negative numbers.  Students formulate expressions and equations in one variable and use these equations to solve problems.

    Solving problems involving scale drawings and informal geometric constructions, and working with two- and three-dimensional shapes to solve problems involving area, surface area, and volume

    Students solve problems involving the area and circumference of a circle and surface area of three-dimensional objects. Students reason about relationships among two-dimensional figures using scale drawings and informal geometric constructions, and they gain familiarity with the relationships between angles formed by intersecting lines. Students work with three-dimensional figures by examining cross-sections. They solve real-world and mathematical problems involving area, surface area, and volume of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes and right prisms.

    Drawing inferences about populations based on samples

    Students compare two data distributions and address questions about differences between populations. They use random sampling to generate data sets and learn about the importance of representative samples for drawing inferences.
