Problem of the Week

Thank you to all those students and families who have worked on the Problem of the Week. The latest winners will be announced at assembly on Monday.

Mild:

Place the numbers, so that each line adds up to 15.

Medium:

The children in class 3C voted on their preferred colour for their new class set of dodge balls. Antoine recorded the results in a column graph but forgot to draw in the column for yellow.

There are 29 children in the class and everyone voted once. How many children voted for yellow?

Spicy:

Here is a triangular pattern. Look at how the counting numbers are arranged. What is the first number in the 13th row?
