  title of easy maths with frogs  
         
 

The maths is everywhere, it is even present when you go up the stairs: one step, two steps, three... A story, too, can be a good starting point or source for a maths exercise, as you saw with Barry and Penguin. Would you like to try now with The Frogs’ Race?

 
 
 
     
 

Exercise:
We know that only one frog crossed the finish line. But how many frogs did actually start the race? Let’s see.

1 – Twenty minutes after the beginning of the race, 7 frogs abandoned the race.
2 – A further 5 frogs gave up twelve minutes later.
3 – Five minutes later, 3 more frogs abandoned the race.
4 – In the next half an hour, 2 more frogs abandoned the race, and only one frog crossed the finish line.

How many frogs were present at the beginning of the race?

- Easy, isn’t it? Check the answers with your teacher or your parents, or send me a message.
