Venn Diagram ChallengeThis resource has two sections. One is for you to practise sorting multiples on a Venn diagram. This is timed and gives a score along with the correct answers at the end of the challenge. Scores are retained in the device’s memory over multiple sessions. The other is designed for teachers to talk through the process. It is not timed or scored and gives feedback as soon as a number is placed.
Caroll Diagram ChallengeThis teaching resource is for both teaching how to use Carroll diagrams and for practising using them. There are two modes: Demonstration Mode: This is untimed and unscored. It gives immediate feedback and numbers can be moved repeatedly. Challenge Mode: This is timed and records scores. Players must allocate the numbers as quickly as possible. Numbers can only be moved until the player goes on to the next number. Each wrong answer incurs a 10 second penalty. Scores are retained on the device for subsequent sessions.
