Meet Freda ...

           

... and Fred.

Fred and Freda were having a race on a 100 square. Freda started at 30 and could jump two numbers every time. Fred started at one and could jump three numbers every time. Who got to 100 first?

Our Rimu mathematicians were on the case.  The majority decided to use a 100 square to help them track the jumps Freda and Fred made. This is how Bella solved this. Can you solve it in a different way?

Once you've solved it, leave us a comment to tell us who got to 100 first and how you solved it.

Is it or ?

Problem Solving

Every second Friday Rimu class works on a math problem. These math problems are based on the idea of low floor, high ceiling - problems that all can access and all can try different strategies to solve it. There are no wrong ideas, or wrong answers, just a good step into the learning pit. 

This week we worked on a Jo Boaler problem called Toothpicks. We had to work out how many toothpicks were in a 3 x 3 shape, without counting. We then went away and worked on the problem of a 2x2, 4x4 & 13x13. How many strategies can we make for each shape? We were super lucky because we had Miss Adams in to help us.
