+
+* **Klasse**: 9A
+* **Datum**: 14.09.23
+
+## Lernziele
+
+1. SuS bestimmen die Quadratzahl der Zahlen 1-20
+2. SuS bestimmen die Wurzel der Quadratzahlen der Zahlen 1-20
+3. SuS leiten die Umkehrung des Quadrierens an Qudraten her
+4. SuS begründen die Definition der Quadratwurzel als eindeutige Umkehrung des Quadrierens
+5. SuS verwenden die Quadratwurzel im Kopf
+6. SuS verwenden die Quadratwurzel mit dem TS
+7. SuS finden Fehler in der Verwendung der Quadratwurzel
+
