Put together Pascal’s Triangle using cards
Calculate Pascal’s Triangle on a piece of paper
Start to spot patterns in Pascal’s Triangle

4. Above, is the start of a pattern of numbers called Pascal’s Triangle
Above, is the start of a pattern of numbers called Pascal’s Triangle. It is named after a French mathematician called Blaise Pascal as he was the first person in Europe to study it in any particular detail.
You will notice that the 6 and 4 are shaded in light green. The 10 beneath them is shaded in dark green. That is because each number is the sum of the two numbers above it.

5. Using the numbers provided, see if you can work out the first 11 rows of Pascal’s Triangle.
If you finish doing this, see if you can spot any patterns in the numbers running down each of the diagonals of the triangle.
