Download the word file here My thinking A question to start Reversing the terms. Does balancing still work? A take-away. How does this effect our balance. Does reversing the terms still lead us to the same answer Increasing the constant by one. What happens? Also: a decimal answer. We can have a negative answer Divide… Read More: Vary and twist : Two step equations »
I know I’d said I’d do simplifying a ratio first but I got distracted. PDF Here | Editable excel file here
Another ‘vary and twist’. This time on inverse proportion. Download it here. I have added a section at the top making explicit that students should make an expectation of the answer before working it out, as I think this is where the power of these types of activity come from. My thinking A question to… Read More: Vary and twist : Inverse proportion »
I’m going to call these Vary and Twist. Section A is some variation practice. Here’s my thinking behind the variations: Simple example Context change, numbers stay the same OK. Now double what we require. answer doubles Amount needed triples, answer triples. Also 6 x first one We’ve doubled the number of pens in the first… Read More: Vary and Twist: Proportion »
A worksheet attempting to combine Craig Barton’s ideas on variation theory (only changing one part at a time) and Dani and Hunal’s ideas around making students make choices. I’ve tried to build up to that. Maybe by trying to combine both I miss the point of each. Download the worksheet here. Would love criticisms and… Read More: An attempt to combine two ideas: dividing in a ratio »
I teach a group with low prior attainment. One thing I noticed is that they often lack the knowledge that other students take for granted, which holds them back. We were discussing the questions “Write as a decimal” and their lack of knowledge that really held them back. I thought back to spelling tests… Read More: Maths ‘spelling’ tests »
I collect misleading graphs. Here’s an excellent one I saw today. What’s wrong with it? There’s more than the obvious. How would you regraph it? Here’s some other weird ones. Although maybe it’s wrong to call these graphs These are ‘infographics’ not graphs. Heathenous maths person… 😉 — TheProvokedPedagogue (@Provokedpedagog) October 9, 2017
I went to Mathsconf13 at the weekend. It was a lot of fun. I would highly recommend attending one. I will be the first to admit that I am not always the most well-behaved during CPD time. I often find it difficult to see the purpose, and it’s often way too generic to be useful.… Read More: This blog is back from the dead »
But I ran out of blocks. How many more blocks do I need? Another…
How many students would know what to do here, or would be brave enough to go with their gut/ spot the pattern?
