Sieve of Eratosthenes Math Activity Grade IV

“Beyond simply leading to better engagement, hands-on learning allows students to practice the skills that they have already learned.”

Colour pencils, a number grid and knowledge of Factors and Multiples, that’s the perfect recipe for Pranganites to find the prime numbers.  Students of Grade 4 did an activity to find out the prime numbers from 1 to 100 using ‘Sieve of Eratosthenes’ activity. There could be no better way other than this activity to sieve out 25 prime numbers using the number grid. Students were actively involved and could easily understand the concept.
