Der CODY-M 2-4 ist ein mathematischer Test für Grundschulkinder, der basale Zahlenverarbeitung (Abzählen, Mengenvergleich symbolisch & gemischt), komplexe Zahlenverarbeitung (Zahlendiktat, Zahlensteine, Zahlenstrahl, fehlende Zahl), Rechenfertigkeiten (Addition, Subtraktion, Multiplikation, Platzhalteraufgaben) und Arbeitsgedächtnis (Visuell-räumlich: Matrixspanne) erfasst. Der Test stellt nur geringe Anforderungen an die Lesefertigkeiten und eignet sich daher auch für Kinder mit Lese- oder Sprachschwierigkeiten. Der Test umfasst Untertests und Skalenwerte für Bereiche wie basale und komplexe Zahlenverarbeitung, Rechenfertigkeiten und visuell-räumliches Arbeitsgedächtnis. Die Ergebnisse werden automatisch ausgewertet und in einem Ergebnis PDF mit “Ampel für Kompetenzstufen” angezeigt. Aus den Ergebnissen wird ein individueller Fördertrainings-Plan erstellt. Der Test ist in DE, EN und FI verfügbar und kann zweimal pro Schuljahr im November und im April eingesetzt werden.
Testgültigkeit:
Konvergente Validität: Korrelation mit dem Mathematiktest ZAREKI-R: r = .83 (N = 157), Korrelation mit dem Mathematiktest HRT 1-4: r = .73 (N = 1.029), Korrelation mit der Mathematiknote: r = -.55 (N = 229), Korrelation mit dem Lehrerurteil „rechenschwach ja/nein“: r = .52 (N = 658)
Diskriminante Validität: Korrelation mit dem IQ (Kurzformen CFT 1-R bzw. CFT 20-R): r = .44 (N = 649), Korrelation mit der Lesegeschwindigkeit (SLS 1-4): r = .48 (N = 633 )
Normen:
Für alle Untertests liegen Prozentrang- und T-Wert Normen für das erste und zweite Schulhalbjahr ab Anfang der 2. Klasse bis Ende der 4. Klasse vor. Die Eichstichprobe umfasst N = 1.064 Grundschulkinder aus 4 Bundesländern sowie N = 111 bundesweit rekrutierte Grundschulkinder mit substanziellen Rechenschwierigkeiten (T-Wert ≤ 40 in einem standardisierten Mathematiktest).
Bearbeitungsdauer zwischen 30 und 45 Minuten.

Good quality ball for large dog, easy to clean
Size: Large, Style: Ultra Tug
It’s challenging to review this because I bought it for my son’s dog, and it doesn’t interest him at all, even though he likes and plays with regular balls. The ball appears to be good quality, which is typical for this brand. He likes to play tug of war, so I thought the combination with a ball would be a hit. The strap looks durable, so time will tell if he develops an interest in playing with this at some point. The ball is hard rubber and fairly heavy, so it should hold up to an aggressive chewer. It doesn’t squeak or make any other noise. It bounces unpredictably and erratically because of the attached strap. Both the strap and ball are easy to clean with soap and water.

A must have if "ball is life"
Size: Large, Style: Ultra Tug, Size: Large, Style: Ultra Tug
If ball is life for your pup this is a great option! Our 70lb mutt is obsessed. We got her the large size for reference. She is not a chewer so we have zero issues with the attached leash/rope part. The ball is the same hard rubber of a typical Chuck-it ball. The rope makes tossing and grabbing the ball from your dog so much easier and cleaner. I also love this helps avoid any choking hazard with typical balls having the rope.

Best and most durable toy for our German shepherd
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
We have a German shepherd. This is our 2nd purchase. The first one was her first and favorite toy.
We still have the first one. But the strap broke (after a year) bc we didn't realize she hid it under blanket, and she chewed it in half. But after a year of hard play, the strap was worn out. She still plays with her ball, and often carries it with her on her walks.
It throws well and I love not having to pick up a slobbery ball. The ball is soft, durable, safe, and easy to play with.

Cord is not durable. Not for unsupervised play.
Size: Medium, Style: Ultra Duo Tug
My dog loves this toy and chewed through the tether in about 15 minutes, making it pretty useless as a tug toy. So the cord is not durable as stated. This is not for dogs who love to chew. Also, it is a bit smaller, much more squishy and chewable than a tennis ball, and I was worried she would chew it apart and that it might get stuck in her throat without the tether, so I took it away, much to her disappointment.
