FOUR RULES OF NUMBER


How many ways can you use the numbers 345 and 6 to create two 2 digit numbers and add them together? What are the largest and smallest totals?


Use number cards to find an answer to the subtractions sum that is as close as possible to the target answer.


Investigation using short division by 7 

Multiplication grids with various numbers missing


Use the numbers 0 to 9 to find all the possibilities of adding 1 and 2 digit numbers together 

Investigating to find the largest possible total when the numbers 1 to 9 are placed in the spaces of a 3 by 3 triangle and multiplication and addition skills are used.
