Why do this problem?
provides a useful context for equations and especially simultaneous equations.
There is also an opportunity to discuss the issue of redundant information.
Jonathan Linton sent us these slides
which aim to present the problem in an accessible way for students.
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?
Learners could go on to Letter Land
or invent their own sweet shop questions.
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.
