1 L4 Teacher's Notes Topic: Number & Algebra Number Grids What is the rule to work out the arrowed numbers? 12 10 20 2 Here are the rules for a number grid. 12 Use the rules to write the missing numbers in these number grids. 12 10 24 947 10 What changes could we make?  change the numbers  change the operations  change the shape  is there always a unique solution for the last type of grid?  could use algebra  use percentages - eg find the left number as a percentage of the right Blank grids are provided
