=====================
Mrs Barker has just bought some yummy treats for her dogs and they can’t wait to eat them. There is just one problem, if the dogs don’t get the same number of treats each, they get seriously cranky. This sounds like a job for Divider Girl. Can Divider Girl use sharing and repeated subtraction to help Mrs Barker share the treats out equally? How might her numberline help? Will they manage to calm the dogs and save Mrs Barker from her position of peril?
This clip is from the BBC series A World Without Maths. In a land where people have forgotten how to do maths, our superheroes, Multiplication Boy and Division Girl, are called upon to save confused citizens from their maths-based predicaments! A series of seven short films to help young children (five to seven) get to grips with multiplication and division.

Teaching Maths?
You could get your class to continue their learning by solving real life division problems. They could use objects, pictures or arrays to share out amounts equally. Some children might use a numberline to do repeated subtraction to divide.
The problems could be based on the story they have watched. For example: Can you help Mrs Barker feed her rabbits? There are 20 carrots and 5 pet rabbits. They must all get the same amount or they will not be happy! How many carrots will each rabbit get? What method will you use to solve the problem? How might you show this in a picture? As a calculation?
You could extend learning by getting pupils to begin to use their multiplication facts to work out the answers, asking ‘How many 5s make 20?’ or 'What is 20 divided into 5?’
Children could mimic the gesture Divider Girl makes with her arms when attempting division problems. Gestures can help with recalling maths terms, linking them to the relevant symbol and making student thinking more visible.
This clip will be relevant for teaching Maths at KS1 in England, Wales and Northern Ireland and at First Level in Scotland.
