About Bigger Piece
Pies with colored slices appear, and an arrow above them asks for the biggest or the smallest amount. Your child compares the colored parts and taps the right one. When every pie has one slice colored, the surprise is that more slices make smaller pieces.
How to play
- Look at the arrow: up means biggest, down means smallest.
- Compare how much of each pie is colored and tap your pick.
- On a computer, pick with the number keys, starting at 1.
What your child practices
- Comparing fractions
- Unit fractions like one third
