What is algebra?
Algebra is arithmetic with a missing number, written as a letter like x, and the job is to find what the letter stands for. If x plus 7 equals 12, then x must be 5. This game gives a child that idea one equation at a time, starting with a single step and building to two, and because every answer is a whole positive number there is nothing fiddly to get in the way of the thinking. The answer checks itself the moment you tap, and the working shows the step that gets x on its own.
How do you play the Algebra game?
An equation appears, such as x plus 7 equals 12, and you tap the value of x from the four choices. Easy stays with one-step adding and subtracting, Medium adds multiplying and dividing, like 3x equals 15, and Hard brings in two-step equations like 3x plus 4 equals 19. The rule throughout is the same, do the same thing to both sides until x is alone, and the working spells that step out every time.
Algebra from grade 5 to grade 8
The seed of algebra, a missing number in a number sentence, is planted in elementary school, but solving equations for x is middle school work, grades 6 to 8. A confident fifth grader can start here on Easy. Because the difficulty is a button, one page carries a child from their first one-step equation to two-step solving. For the multiplication and division that algebra leans on, our math games keep those facts sharp.
Frequently asked questions
What does the Algebra game practice?
Solving for x in simple equations, the first real algebra. You find the missing number in one-step equations like x plus 7 equals 12, and in two-step equations like 3x plus 4 equals 19. Every answer is a whole positive number, it checks itself the moment you tap, and the working shows the step that isolates x.
How do you solve for x?
You do the same thing to both sides until x is alone. If x plus 7 equals 12, take 7 off both sides to get x equals 5. If 3x equals 15, divide both sides by 3 to get x equals 5. A two-step equation undoes the adding first, then the multiplying. The game shows that step on every question.
What grade is this algebra for?
The idea of a missing number starts in elementary school, but solving equations for x is middle school, grades 6 to 8. A confident fifth grader can start on Easy with one-step equations. Move up to multiplying and two-step equations as each one becomes comfortable.
