About This Practice

Between 0 and 1 live more than fractions—there are decimals too: 0.1, 0.2, … the tenths; and between them, one hundred slices give 0.01, 0.02, … the hundredths. Look closely with the magnifier and you can find any decimal's home.

How to Play

Read the target decimal, say 0.43.
Tap the main line to pick a part—the magnifier opens it into 10 hundredth ticks.
Tap a zoomed tick to place the marker and read its decimal.
Tap Check; if you miss, a hint tells you which way to go.
Use the arrows to explore other parts, then tap New Target.

Learning Objectives

Locate tenths ticks (multiples of 0.1) on a 0–1 number line.
Understand that 10 hundredths hide between each pair of tenths.
Pinpoint decimal positions to 0.01 with a zoomed line.
