    Rational Functions and Jewelry Production

    Math SL is a Diploma Programme (DP) course for grades 11 and 12, yet I’m unit planning in the IB Middle Years Programme (MYP) style since it’s consistent with our grades 6-10. MYP math has four criteria: A – Knowing and Understanding, B – Investigating Patterns, C – Communicating, and D – Applying Math in a Real-Life Context. I’ve been racking my brain to come up with an authentic assessment (not a test) for my Rational Functions Unit. In this unit, we are focusing on the following objectives from the IB Math SL syllabus: 2.5 The reciprocal function x → 1/x, x ≠ 0, its graph and self-inverse nature. The…

My first period 9th grade class doesn’t seem to have…

    math in real life: blackout shades

    I’m researching blackout shades for our nursery and started my design process by polling a few mom groups. One mom suggested Pottery Barn Kids. These Harper shades are lovely, on sale, and have been positively reviewed at Embrace My Space. However I realized that they wouldn’t work for our nursery upon seeing that all variations were 64″ long. Our windows are almost floor-to-ceiling. I went in to measure the window widths to see if curtains might work. A friend recommended these Koala Baby curtains, but they would be too short. These Harper curtains come in varying lengths that could potentially be tall enough. However, the smaller windows are approximately 22″ and the…
