Two, three, five, seven... Time to hit prime number heaven! If you're looking for a little something extra for your class at the end of your prime number lesson, check out this Year 6 Primes to 100 extension activity! Does it work as an in-class extension? Yes. Is it ideal for homework? Absolutely. Does it come with three levels of differentiation, a mixture of varied fluency and reasoning questions at each level, and an answer sheet that can be used to help you or your children mark the work? You betcha.

The highest prime number you could cover in this lesson is 97. That's just 3 away from what I'd give this resource out of 100. And I'm not thinking 94.
