Using the iPad to help our understanding of Prime numbers and factors

In Numeracy today, the children were taught about prime numbers and factors and then practised this using the app “Factor Samurai,” an app that is very similar to the popular “Fruit Ninja,” game however has a mathematical focus to it.

The lesson started by the children trying to define prime numbers and factors and then trying to find some examples. I then explained the rules of the app and shared the how to screen.

The aim of the game is to slice a number with more than 2 factors to split it into two factors and continue to slice until they break into their lowest prime number form. You have three lives and lose a life if you slice a prime number. Points are scored every time a number is correctly sliced however if a number is missed points are deducted.

The app was a really interactive and enjoyable way of learning which numbers are prime numbers and the factors of others. The children thoroughly enjoyed the game and could list prime numbers quickly when asked at the end of the lesson and also recall factors of numbers. The competitive element to the game engaged most of the children and they relished the challenge trying to get the highest score in the class.
