generalise a number pattern
Multiplication and Division, AM (Stage 7)
Prior Knowledge:
- complete an easy Sudoku puzzle
Background:
These exercises use the structure of the common Sudoku puzzle to explore the sums of patterns of numbers. It is important that students know that each row, each coloumn and each 3x3 block of 9 in the puzzle all have the same sum. The puzzles drawn may be completed by students although it is the same one altered for each different set of numbers. Exercise 8 is a summary sheet which serves as a self check. The final code is 02 453 472.
Note a sequence is an infinite list of numbers such as 1,2,3,4,5… such that the pattern is obvious. A series is the sum of a finite sequence for example 1 + 2 + 3 + 4 + 5… n.
