Grade: 6

 

Sample Activities:

 

·        Students build rectangular arrays with square tiles to determine which of the first fifty counting numbers are rectangular (composite) and which are non-rectangular (prime).

 

·        Students use the Sieve of Eratosthenes to generate a list of all the primes in the first 100 counting numbers.

 

·        Students use common multiples to solve problems like this: Hot dog buns come in packages of 8. Hot dogs come in packages of 6. What is the smallest number of packages of each that can be bought so that there are no extra buns or hot dogs?
