Liam and Ollie aged $8$ wrote;
To solve the problem we started by looking at the triangles. They
were three because $12$ divided by $4 =3$.
The circles are two because in the third row we had two threes and
two circles $6+4=10$.
The diamond and the hexagon then had to be $1$ or $5$.
The diamonds had to be worth $5$ because if you put a $5$ for the
hexagon in the fourth column it wouldn't work because then
the total would be bigger than $5$. So then the hexagons had to be
Sophie wrote a very clear description of her
thinking and working;
Firstly I worked out the value of the red triangles. Column
two had four red triangles that added up to twelve. Twelve
divided by four is three.
Next I worked out that the yellow circles are two. I did this by
looking at row three, this had two triangles and two circles that
added up to ten. The two triangles added up to six leaving four
remaining which divided by two is two.
Next I worked out the value of the hexagon was one. Column four had
to add up to five and had a circle and a hexagon already in it. As
the circle equals two and the triangle equals three and the number
had to be below five, that left four and one, it could only be one
because there are two spaces left and the other two spaces already
made three leaving one as the only available option.
Finally the blue diamond was five because the top row contains one
of each shape and adds up to eleven, the triangle plus the circle
plus the hexagon equals six. Eleven take away six is five.
