Hi all. Today I started seriously tackling arrays and loops with the kids, so I threw together some exercises for the kids.<br><br>Attached, with solutions. Enjoy.<br><br>BTW, I had a breakthrough moment with kids' recognition of the importance of algorithms today. I asked them how you would thinking goes into choosing what notes and coins (and how many) you would need to give someone a certain amount of change. They could all do it, obviously, but working out the strategy had them truly stumped for a while. It led neatly into the importance of verbalising and expressing algorithms because they couldn't create code from intuition.<br>
<br>We walked through a strategy on the board using concrete test data examples, and then coded it with arrays and loops and it all fell together nicely.<br><br>I then moved on to 2D arrays, then got carried away and introduced them to 3D and 4D and 5D arrays, which perhaps was a little much...<br clear="all">
