What does a student learn in StateMissouri,GradeGrade 7,SubjectMathematics?

Proportional relationships show up everywhere: recipes, maps, sale prices, speed. Students learn to spot them, set up ratios, and use those ratios to solve real problems with numbers that scale together.

Two quantities are proportional when they grow (or shrink) at the same steady rate. Students look at a table or graph and decide whether the relationship between two values stays constant throughout.

Reading a graph of a proportional relationship, students explain what a specific point means in real terms. If a point shows (3, 12), they can say what the 3 and the 12 represent in the actual situation, like 3 hours and 12 miles.

Real-world math problems involving percentages, rates, and ratios. Students figure out things like sale prices, unit costs, and how long a trip takes at a given speed.

Adding, subtracting, multiplying, and dividing with negative numbers, fractions, and decimals. Students extend the number rules they learned in earlier grades to work with any rational number on the number line.

Adding a number and its opposite always equals zero. Students learn to recognize these pairs, like 5 and -5, and explain why they cancel each other out.

Students explain what an answer means after adding or subtracting fractions, decimals, or negative numbers. For example, they can say whether a sum shows a gain or a loss, and how far it lands from zero on a number line.

Flipping a fraction and multiplying it by the original always gives 1. Students learn why dividing by a number works the same as multiplying by its flipped version.

Students connect multiplication and division of fractions, decimals, and negative numbers to real situations, like splitting a debt or scaling a recipe. The math tells a story, and students explain what the answer actually means.

Students practice adding, subtracting, multiplying, and dividing with fractions, decimals, and negative numbers to solve real-world problems.

Students rewrite math expressions into simpler or different forms using rules like the distributive property and combining like terms. Two expressions that look different can mean the same thing.

Students rewrite expressions like 3(x + ½) by distributing, combining like terms, or pulling out a common factor. The numbers involved can be fractions or decimals, not just whole numbers.

Students rewrite expressions in a different but equal form to make a problem easier to read or solve. The goal is to see the same math written a new way so the numbers and relationships are clearer.

Students use numbers and letters to write expressions, set up equations, and solve real problems. This is where abstract algebra starts doing practical work: finding unknown values, checking solutions, and building the habits that carry into higher math. Wait, that's too long and has an em dash issue. Let me redo. Students write and solve equations and expressions to find unknown values in real problems. They move between words, numbers, and algebraic notation to set up and check their work.

Students check whether an answer makes sense by estimating or doing quick mental math before accepting a result. This habit catches errors that a calculator or written work can miss.

Two-step equations ask students to find a missing number using two math operations, like multiplying and then adding. Students solve equations such as 3x + 5 = 20 and explain what the answer means in the real situation the problem describes.

Students write and solve inequalities with a variable, like 3x + 5 < 20, then show all the solutions on a number line. The numbers involved can be fractions or decimals, not just whole numbers.

Students draw and label geometric figures, like triangles and quadrilaterals, then explain how those shapes relate to each other in size, angle, or position.

A scale drawing shrinks or stretches a real object so it fits on paper. Students figure out the actual size of rooms, buildings, or shapes from that drawing, then redraw it at a new scale.

Students learn how the distance across a circle, the distance from center to edge, and the area inside it all connect through the number pi. Change the radius and every other measurement changes in a predictable way.

Students practice using two formulas for circles: one finds the distance around the edge, the other finds the space inside. They apply both to solve real problems involving circular shapes.

Students use what they already know about angles, area, and volume to solve harder problems, like finding the space inside irregular shapes or figuring out how much a 3-D object holds.

Students find the area of shapes like triangles, parallelograms, and irregular polygons by breaking them into simpler pieces. They use what they know about rectangles and triangles to calculate the total space inside each shape.

Students find the amount of space inside 3D shapes like boxes, pyramids, and cylinders, and calculate the total area of their outer surfaces. Both skills use formulas students apply step by step.

Students learn to survey a small, randomly chosen group and use those results to make reasonable predictions about a much larger group, like estimating how many kids in a whole school prefer a certain lunch.

A sample only tells you something true about a larger group if it reflects that group fairly. Students learn why a survey of just one neighborhood, for example, can't speak for a whole city.

Students compare two groups using real data, like survey results or measurements, and draw conclusions about how the groups differ or overlap.

Students compare two sets of data by looking at the mean, median, or spread to draw conclusions about which group is higher, more consistent, or more spread out.

Students learn to predict how likely an event is to happen, build simple models to test those predictions, and compare what the model says to what actually occurs.

Students figure out how likely a single event is to happen, such as rolling a specific number on a die or picking a certain card from a deck. They express that chance as a fraction, decimal, or percent.

Probability is a number from 0 to 1 that shows how likely something is to happen. A probability of 0 means it can't happen; a probability of 1 means it will. Numbers in between show how good the chances are.
