What numbers practice looks like

Numbers games are mental math you can do in a minute: sums against the clock, placing a number on a line, matching fractions and finding the missing sign.

They start with small numbers and grow as you clear levels. A wrong answer costs a heart, not your progress.

You’ll practice

  • Mental arithmetic. Working sums out in your head without paper.
  • Working memory. Keeping a running total in mind.
  • Processing speed. Answering accurately at pace.
  • Number sense. Knowing how big a number is compared with others.
