Why do this problem?
This problem provides a useful context for equations and especially simultaneous equations.
There is also an opportunity to discuss the issue of redundant information.
Possible approach
Jonathan Linton sent us
these slides which aim to present the problem in an accessible way for students.
Key questions
How much does one lollypop cost?
Would it be a good idea to see what Kenny bought next?
What did Nathan and Judy both buy?
Would it be helpful to write it all out as equations?
Would it be a good idea to call the sweets b, c, m and l?
Possible extension
Learners could go on to
Letter Land or invent their own sweet shop questions.
Possible support
Suggest starting by working out the cost of lollipops from what Liam bought. Next look at what Kenny bought. Then continue through the other children's purchases.
