This problem solving activity has a number (all operations) focus.
On Monday, Sam and Sylvia share some lollies.
Sam has 2 lollies. Sylvia has 4 lollies.
Together, how many lollies do they have to share?
If Sam has 2 lollies, and Sylvia has 4 lollies on Tuesday and Wednesday too, how many lollies do they each have?
What is the total number of lollies that Sam and Sylvia share in three days?
Students apply addition strategies to solve this problem.
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. At each level, these problems become more algebraically-focused.

What is the total number of lollies that Sam and Sylvia share in three days?
If Sam and Sylvia have a different number of lollies each, but have 10 lollies altogether to share, how many might they each have?
To begin, Sam and Sylvia have a different number of lollies each, but when they share them fairly they each get 6. How many might each person have started with?
The number of lollies they share is the sum of what each got: 2 + 4 = 6. Each day, they each have half the share of the lollies (i.e. 3).
Over three days Sam got 2 + 2 + 2 = 6. Sylvia got 4 + 4 + 4 = 12. Sylvia got double Sam's number. Together they have 18 to share. This can also be seen as follows: Each day they shared 6 lollies (2 + 4). 6 lollies x 3 days = 18.
Combinations to 10: (1,9) (2,8) (3,7) (4,6) (5,5) (6,4) (7,3) (8,2) (9,1) Sam has the first number and Sylvia the second number.
Combinations to 12: (1,11) (2,10) (3,9) (4,8) (5,7) (6,6) (7,5) (8,4) (9,3) (10,2) (11,1) Sam has the first number and Sylvia the second number.
