Circuit Maths

This interactive whiteboard resource is intentionally fast paced to encourage students to estimate and consider what answer looks correct without necessarily working it out accurately. The fast pace also ensures a number of students can have a turn at the front of the class without taking up to much time.  Class questioning could consider what ways we can check whether an answer looks right.  I.e. adding 2 odd numbers will produce an even answer, rounding to the nearest ten and then adding for an estimated answer etc.

Borrowing the idea of diffusing a bomb from television drama the students need to connect the components together based on the addition questions and answers.  Click and drag from the question to the answer (or vice-versa).  Every failed connection results in sparks and a 5 second time penalty so accuracy is important.

This resource has sound so ensure your speakers are at an appropriate level.

As always if you encounter any bugs or problems please report it here.  If you like this resource and would like it applied to another concept or have a suggestion to improve it also leave your comment.

    I love your resources and use them regularly – quick comment about this one, you can’t really see the ‘Well Done’ as it’s in black, on a mainly dark background.

    Strike that last comment, maybe my laptop was just not at a great angle!

    Actually I think you make a good point. The contrast on an IWB won’t be as good as on a monitor so the colour probably should be lighter. I will experiment with different colours.

    Thanks for letting me know.

    I love this! Are you planning to do more of the same with different types of problems?

    Thanks

    I can do. I generally wait to see how much something is used/what the feedback is. Then it depends if I can find a way to incorporate other problems. I’ll put this one on my list to update.

    This addition game is great. I plan to use it with my kids in class next week.

    Do you plan to incorporate a way to keep track of a score, which ever this may be? I was thinking the number of stages advanced.

    Excellent job on the design!

    Thanks. That’s a good idea – I will try to come back to this and see if I can implement that. I will add it to the game I’m working on at the moment though.

    Thanks. I’m currently working on few small updates for this such as varying the timing. I’ll try to put an easier mode in too.
