How to use this review

  • Do the review in two short sittings if your child gets tired. Each section matches one lesson.
  • Go outside if you can: look at the Sun's position, shadows, weather and signs of the season while answering.
  • Ask "How do you know?" Good answers use clues like the Sun's position, temperature, or what animals are doing.
  • Note which section had mistakes and revisit that lesson.

For parents and teachers

Use mistakes to choose what to revisit. Each review section matches one lesson.

  • Thinks the Sun moves around Earth or "goes to sleep", or can't explain shadows: revisit The Sun Gives Us Light and Heat and do the shadow tracker.
  • Mixes up the order of the day, or doesn't understand "cycle": revisit Day and Night: A Daily Cycle and make the cycle wheel.
  • Mixes up seasons or their weather, or thinks summer happens because Earth is closer to the Sun: revisit The Four Seasons and Their Weather and keep a weather chart.
  • Thinks all animals hibernate, or doesn't know how trees change: revisit Plants and Animals Through the Seasons and take a nature walk.
  • Can't name ways people prepare for weather, or innovations: revisit How People Get Ready for the Seasons and try the ice cube shelter again.

A few mistakes are normal. Praise answers that use clues and observations from real life.
