Elapsed time
Two clocks. Find the gap. Includes cross-hour, cross-noon, and cross-midnight variants for fourth graders.
- Within-hour problems for grade 2
- Across-hour problems for grade 3
- Cross-noon and cross-midnight gotchas for grade 4
- Analog-analog, digital-digital, or mixed pairings
The cross-noon gotcha
Students who can compute 11:30 - 9:00 perfectly will still trip over 11:30 AM to 1:00 PM, because the hour resets at noon. The Playground's concept-lesson rail walks through this gotcha explicitly.
Two strategies, one answer
Counting up vs counting back. Both reach the same elapsed time. The worksheet builder mixes both approaches so students see the equivalence.
