Each symbol has a numerical value.
The total for the symbols is written at the end of each row and column.
Can you find the missing total that should go where the question mark has been put?
We used all of the Learning Gems to help us solve the problem. Some of us were so good we went to show Mrs Ross how brilliant our problem solving skills are. She was amazed at how quickly we solved the problem (the quickest were 6 minutes - although it took them a bit longer to prove it!)
We all worked hard to explain our thinking and share our methods with eachother.
Fantastic maths investigating!
