Please, no more rubbish about times tables!

The human adult spine has 33 vertebrae, the bones that support the rest of the body.  The lumbar vertebrae, in the lower back, bear the weight of the upper body and are very flexible.  If you have lower back problems, it’s often your lumbar vertebrae that are struggling under the weight they have to bear.

Multiplication is a lumbar vertebra in the spinal column of mathematics.  Multiplication supports the weight of, amongst other things: Continue reading “Please, no more rubbish about times tables!”

Adventures in Mastery 5: Making Connections

I taught my year 7 class today and had the most wonderful time.  I really love my year 7s, they’re so enthusiastic.  So far this year we’ve done place value, rounding, four operations (with natural numbers and decimals), powers, roots and primes, negative numbers, order of operations, fractions (including four operations) and are early into our unit on percentages.  Today it was common FDP conversions (quarters, eighths, fifths, thirds, ninths, etc).

Adventures in Mastery 4: Lesson Sequences

In my maths department we are starting on a journey of building a new curriculum based on the principles of mastery.  To find out what mastery is, read Mark McCourt.  Implementing something different comes with all sorts of challenges but, if it’s a good thing to do, it brings benefits too.  One of the benefits I am finding this year is the liberation from the compulsion to produce a three- (or four- or five-) part lesson with objectives and mini-plenaries and some kind of forced activity to (falsely) demonstrate the “progress” my students have made over the course of an hour.  By having a curriculum with clear aims and (hopefully) coherent thinking underpinning every aspect I feel more confident to teach the way I feel will be most effective rather than making my lessons a conflation of lots of “best practice” techniques in order to satisfy a checklist.
