  • Also fixed now. Thanks all!

  • I believe we've now fixed it. Apologies and thanks all for spotting!

  • Thanks Sally!

  • You'll need to register on the stem site- completely free and shouldn't take too long!

  • "x is a-cross" ;-)

  • Not neccessarily, students don't need to know the quadrant name, just to be confortable redaing/plotting points in all four.

  • Very true! We also had to use pen when drawing graphs so that the lines/points can be seen clearly, going very much against what I tell students about using pencil!

  • Welcome back @WilliamHarris

  • You can see why these signs are confusing!

    40:100, or 2:5 would mean that for every 5 units we move along the road, we move 2 units up (or down), i.e. a ratio of 0.4 : 1 or (2/5) : 1. THe vertical distance travelled is two-fifths of the horizontal distance trvelled.

    BUT in maths classrooms students are taught (correctly) that the ratio 2:5 gives...

  • Great to have you with us!

  • Welcome!

  • To avoid the graphing element, I've asked students to draw a table with "C", "d" and "C/d" columns. Although I think the graph/gradient aspect is a nice addition to the learning!

  • It's a nice gentle introduction to (or foreshadowing of) graphical transformations!

  • Using Desmos during lockdown has been a game-changer!

  • Hi @JulieFairless- sorry for not getting back to you sooner.

    Sudoku is a good comparision- you need that kind of logic! As we are dealing with multiplication, the key is to look at the numbers already filled in and think about what could have been multiplied together to make them. A bit of guess work might be needed- so use a pencil!

    For the 24, it...

  • Werlcome back @RobertDrury. And don't worry about the "cheating"!

  • See you there Sarah!

  • Sounds exactly what I did when first presented with this problem!

    P.S. I agree with you!

  • Thanks for this @SukhdevSingh

  • Great to hear!

  • Very kind Louisa! Glad you enjoyed it!

  • Thanks Helen!

  • Hi @KarenaCS- the answer sheest are on the last step of each week!

  • It should be right at the end of the week, the last step, in the downloads section...

  • Thanks all!

  • It's good that we are talking about methods, not just answers!

  • Great to have to have you on the course!

  • Great to hear Kerry!

  • @JudithL why did you doubt yourself?

  • Isn't maths great?!

  • Sounds like a great idea to me!

  • See you there!

  • Thanks both- I'll look into it...

  • Perhaps thinking of 33 1/3% as a fraction will help?

    1/3 of 12 then gives 4...

  • Our pleasure!

  • Glad you stuck with it!

  • Thank you @MadeleineBrooks-Kenney, that is very kind!

  • That's great to hear @LindaHooper!

  • Sorry to hear that our conversation came across that way! :-/

    We try to have one person asking and one person answering in each video (swapping each time...)

  • Hi @FatimaMughni- the worksheet is for your own learning and reflection. Please add comments here based on the worksheet questions if you like!

  • It is in the downloads section in step 1.1

  • Now there's an investiagetion!

    "What value less then 100 uses the most digits when written in Roman numerals..?"
