About this activity
Dans une cour d'école enneigée en 3D, les élèves trouvent la règle de suites croissantes et décroissantes de forts de neige, construisent le terme suivant, un terme manquant et un terme d'avant bloc par bloc, et font des prédictions proches et lointaines jusqu'à 100.
What students learn
- Determine the rule of a growing or shrinking pattern that changes by a constant amount (2, 3, 4, 5 or 10) that does not start at the change
- Extend a pattern of snow forts, including forts that grow in two or four places at once, where the shape matters as well as the count
- Identify a missing term in the middle of a pattern and build it
- Make a near prediction (rang 5) and a far prediction (rang 8) without building every term
- Work a shrinking (décroissante) pattern forwards and backwards, and describe a pattern of tens climbing toward 100
