What 7th graders practice in these games

These are the Common Core State Standards for grade 7 that the games above practice, quoted from thecorestandards.org. Each one links to the games where students work on it.

7.EE.A.1 Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.Practiced in: Parentheses: Expand & Factor, Expressions & Substitution
7.EE.B.3 Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.Practiced in: Simple & Compound Interest
7.EE.B.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.Practiced in: Equations & Balance, Inequalities
7.G.A.1 Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.Practiced in: Scale Drawings & Maps, Congruent & Similar Shapes
7.G.A.2 Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.Practiced in: Compass Constructions
7.G.B.4 Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.Practiced in: Circles
7.G.B.5 Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.Practiced in: Angles, Angles in Polygons
7.G.B.6 Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.Practiced in: Volume, Triangle & Parallelogram Area, Surface Area
7.NS.A.1 Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.Practiced in: Negative Numbers
7.RP.A.1 Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.Practiced in: Speed, Distance & Time
7.RP.A.2 Recognize and represent proportional relationships between quantities.Practiced in: Ratio & Proportion, Scale Drawings & Maps
7.RP.A.3 Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.Practiced in: Simple & Compound Interest
7.SP.C.5 Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.Practiced in: Probability
7.SP.C.6 Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.Practiced in: Probability
7.SP.C.7 Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.Practiced in: Probability

How to use these games in class

🚀 Starter (5 minutes)

Project Simple & Compound Interest and ask what a 20% discount does to a $50 price. Let students predict, then check the sale price in the game.

🧩 Station (10–15 minutes)

Pairs use Circles to wrap a string around a circle and slice it, then say in their own words how circumference and area are related.

🏠 Homework

Send the Probability link home. Students run a spinner or dice experiment and compare the results with the chance they expected.

Questions teachers and parents ask

What math do 7th graders learn?

Common Core names four focus areas for grade 7: proportional relationships, operations with rational numbers and linear equations, scale drawings, informal constructions, and area, surface area and volume, and drawing inferences about populations from samples. These games cover the first three. Probability is covered; sampling is not.

Is there a game for circles?

Yes. Circles covers radius, diameter, wrapping a string around a circle and slicing it to find its area. That matches Common Core 7.G.B.4, which asks for the circle formulas and an informal derivation of how circumference and area relate.

Are these math games free, and do students need an account?

Yes, they are free. Students do not need an account, a download or an email address: open the link in a browser on a Chromebook, tablet, laptop or phone and play.

How do the levels, missions and stars work?

Most games have three levels, so a student can start easy and move up: a free play mode where nothing can go wrong, missions that award up to 3 stars, and a short timed challenge with no penalties.
