Grade 7 Math
In 7th grade math students will solve real-world problems using ratios, rates, and proportions. For example, find how much tax will be charged on a new phone. Understand and use rational numbers (positive and negative fractions). For example, track the depth, in miles, of a submarine over time. Solve problems involving a circle’s area, radius (distance from center to edge), and circumference (distance around the edge). Compare two sets of data. For example, compare the heights of players on two basketball teams.
By The End of Seventh Grade, Students Can:
- Explain the concepts of unit rate and proportion.
- Add, subtract, multiply, and divide positive and negative fractions.
- Explain connections between addition, subtraction, and negative numbers.
- Rearrange math sentences (equations) using variables: for example, change 4x + 2 = 10 to 2(2x + 1) = 10.
- Write equations and inequalities to solve real-life problems: for example, write 20h = 500 to find how many hours someone needs to work at $20 an hour to get $500.
- Make scale drawings of geometric figures, changing their size without changing their shape.
- Use knowledge of special types of angles (like supplementary, vertical, and adjacent angles) to find the size of an unknown angle.
- Explain how and why to use a sample population in research.
- Compare the probabilities of two events using a scale from 0 (definitely not going to happen) to 1 (definitely going to happen).
- Find the probabilities of events that depend on one another to happen (are compound).
