🎯 Estimate the Spot
Estimate where a number sits on a line with only its ends marked: 0–100, 0–1000 or 0–10 000. Closer guesses score more.
How to play
Only the two ends of the line are labelled. Think about where halfway is, then quarters, and tap your best estimate. Landing close enough counts as correct, and a near-perfect landing earns bonus points.
⌨️ Keyboard: ← and → move the marker, Enter jumps.
What it teaches
Estimating on an empty number line builds number sense – the feel for how big a number is compared with others. It supports rounding, checking answers for reasonableness and reading scales in science and maths.
Levels: 0 to 100 (Halfway mark shown) · 0 to 1000 (Ends only) · 0 to 10 000 (Ends only, tighter target)
