Each day of December, tinsel is placed between the baubles showing 1-9 in such a way that each set of numbers can form an equation that equals the day of the month.
Arrange the digits 0-9 in three rings going clockwise. Using different diameter lines that go through the different digits, how many of the five additions total over 1000?
A triangular grid contains the numbers one, two and three. Combine them into regions with unique totals. What is the lowest possible value of the region with the highest total?
Explore chains of numbers by adding the ones digit and then doubling or halving. Do all numbers loop? Do they follow similar loops?
Create chains by adding single-digit numbers. Each number is inside either a triangle, a square or a hexagon. In each polygon, the number must include a digit that is the same value as the number of sides in the polygon.
With a hexagon of dots, draw lines between them. After the first line is drawn, each new line must intersect exactly one line. Explore further with curved lines or different dot positions.
With this island on addition, it takes a little bit to set it up but once you have done so, it’s fairly easy to follow and the patterns are quite surprising. It’s an example of when maths at first just…
This island focuses on adding money and involves strategy in placing coins to ensure the greatest amount is obtained. What is nice is that they have to continually think about their strategy. It might change a bit from example to…
This island involves starting with shapes made with elastic bands on Geoboards and ‘pulling’ the sides out over the nearest peg – trying to avoid making right angles for as many turns as possible. We start focused on a scalene…
Using a dotted square with numbers, join lines between dots so that a line is only ever intersected at most once. What is the lowest total possible from unjoined dots?
