What 4th graders practice in these games

These are the Common Core State Standards for grade 4 that the games above practice, quoted from thecorestandards.org. Each one links to the games where students work on it.

4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.Practiced in: Lines, Triangles & Quadrilaterals
4.G.A.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.Practiced in: Shapes & Symmetry
4.MD.A.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...Practiced in: Measurement
4.MD.A.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.Practiced in: Money
4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.Practiced in: Perimeter & Area
4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.Practiced in: Angles
4.MD.C.7 Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.Practiced in: Angles, Tessellations
4.NBT.A.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.Practiced in: Place Value
4.NBT.A.3 Use place value understanding to round multi-digit whole numbers to any place.Practiced in: Rounding & Estimation
4.NBT.B.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm.Practiced in: Add & Subtract
4.NBT.B.6 Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.Practiced in: Division
4.NF.B.3 Understand a fraction a/b with a > 1 as a sum of fractions 1/b.Practiced in: Fraction Operations
4.NF.C.6 Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.Practiced in: Decimals & Percent
4.OA.A.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.Practiced in: Tape Diagrams & Bar Models
4.OA.B.4 Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.Practiced in: Factors, Primes & Even/Odd
4.OA.C.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.Practiced in: Sequences & nth Term, Patterns & First Algebra

How to use these games in class

🚀 Starter (5 minutes)

Project Angles and open an angle to 90 degrees. Ask students to show an acute and an obtuse angle with their arms before you reveal each one.

🧩 Station (10–15 minutes)

Pairs work through Fraction Operations on a tablet or Chromebook and write one fraction equation from each round on a recording sheet.

🏠 Homework

Send the Factors, Primes & Even/Odd link home. Students find all factor pairs of a number up to 100 and decide whether it is prime or composite.

Questions teachers and parents ask

What math do 4th graders learn?

Common Core names three focus areas for grade 4: multi-digit multiplication and division, fraction equivalence, adding and subtracting fractions with like denominators, and multiplying fractions by whole numbers, and analyzing shapes by their parallel and perpendicular sides, angle measures and symmetry.

Is there a game for measuring angles?

Yes. Angles lets students open the arms of an angle, read a protractor and find missing angles. That matches Common Core 4.MD.C.6 (measure angles with a protractor) and 4.MD.C.7 (find unknown angles by adding and subtracting).

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.
