Applying our Problem Solving Skills!

In Numeracy today, Year 5 looked at a problem solving activity but then applied it using the iPads.

The lesson started with the question “Can you find all the different ways of adding numbers to make the number 10?”

Straight away, shouts of “easy” were heard and children noted all the number bonds using 2 numbers – We listed them on the board: 1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5.

“Was that all the possibilities?” I asked, “Can I only use 2 numbers?” Then we got the ball rolling. Children started working on 3 number combinations, 4 number combinations. We then looked to see if we can work systematically to find all the possibilities, we found that we had to use known number bonds of other numbers to help us, splitting the number 4 into 2 + 2 or 3 +1.

 

 

 

 

 

 

 

 

Once we had all as many possibilities as possible, we then use this knowledge to apply it into a puzzle based challenge game, called ‘Numbers: Logic puzzle.’ The game is simple, clear the coloured squares by making combinations of numbers to 10 as long as they are above, below or next to them. A screenshot of the challenge looks like this:

Straight away the children were engaged with the challenge and straight away started applying the knowledge from the problem solving activity. Adding in the challenge or playing against someone and the challenge being timed, engaged nearly every child. All the children enjoyed and were using 4, 5, even 6 numbered combinations.
