Up to 4 players can try to get their penguin back to the homeland first.  You can play other players online or against the computer. Players jump on the iceberg that has the correct answer to the multiplication problem. It certainly forces you to think quick, but get the wrong answer and you are in the drink!

I have added a link to this game on the ‘Students’ page as well.

Arrays: Factor Families Description

Make equal rows and columns to explore how numbers can be broken up into factors. For example, the number 24 can be expressed as 12×2 or 2×12, and therefore, it can be divided equally using its factors 12 and 2. Identify a missing factor to complete a factor family. Solve four expressions: two multiplication and two division statements. This learning object is one in a series of five objects.
