This problem solving activity has a number (multiplication, division, and addition) focus.
On Monday, Sam, Sonny and Sylvia share some lollies they'd been given.
Sonny got half as many lollies as Sam, and Sylvia got a third as many lollies as Sam got.
They got the same number of lollies each day up to (and including) Friday.
If Sam got 18 lollies on Wednesday, how many lollies did Sonny get on Thursday?
How many lollies did Sylvia get that week?
In this problem students apply a range of strategies to solve fraction problems that involve one half and one third. Look for students to use a range of strategies including drawing and equipment.
This is one of six problems: Lollies!, Number, Level 1; More Lollies, Number, Level 1; Sharing More Lollies, Number, Level 2; Lollies, Lollies, Lollies, Number, Level 3; and Still More Lollies, Algebra, Level 4. These become increasingly algebraic at each level.

How many lollies did Sylvia get that week?
Sonny gets half as many lollies as Sam. Sam gets 18 and half of 18 is 9. Sunny got 9 lollies.
Since Sam gets 18 lollies on any day and Sylvia gets a third of that, then Sylvia gets 6 lollies. Five lots of six is thirty.
