About this game
One-step equations: a free Grade 6 math game for ages 11-12. Kids solve one-step equations with addition and subtraction. Each round brings 10 fresh questions with new numbers; instructions are read aloud and every answer is checked.
Every equation here hides one number behind the letter x. One-step equations gives cards such as x + 20 = 37 or x â 14 = 8, with new numbers on every card and answers from 1 to 50. Ten cards make a round in this Grade 6 game. Your child types the value of x, and each answer is checked straight away. A hint is one tap away when a card stalls.
Solving means undoing. Whatever happens to x, the opposite operation on both sides gets it alone: subtract 20 from both sides of x + 20 = 37 and x is 17. The hint says the same thing in one sentence. Cards that add and cards that subtract come mixed, so the opposite operation keeps switching, which is exactly the habit later algebra leans on.
Copying the sign is the trap. On x â 3 = 15, subtracting again gives 12, a number that does not fit. Ask, "If x were 12, would 12 â 3 make 15?" Putting the answer back into the equation is a check your child can always run. Close with, "You checked by putting x back in."
