In #mathstoday I came up with a new tool on solving quadratic equations using factorising.

www.interactive-maths.com/solving-quad...

You can choose what you reveal or hide giving lots of flexibility.
Screenshot of an applet with the quadratic equation hidden, one factorised bracket revealed to be (x+1) and one solution revealed to be x=7.

I really do think that colour is helpful to identify steps in multi stage problems. But there is also scope to use it to link parts of a solution to the words in the question.
Solution to a question on finding the equation of the perpendicular bisector of points (4,-3) and (-2,7). Use of colour to highlight how parts connect to the question words.

Create a Question Strip, great for starters. Same set of questions on each side.

This one is on Differentiation of Polynomials.

Took 30 seconds as I regenerated the questions to get them to increase in difficulty.

Worksheet created in 10 seconds on straight line graphs. Nothing fancy, just a few questions. Great for a starter or retrieval activity.

You can also make a Codebreaker, odd one out, loop cards.

I have added a new topic to my generators: Gradient.

Find gradients from lines, draw gradients, gradients from two points, missing coordinate given gradient.

Turned into worksheets, treasure hunt, matching cards.

A new tool to help with IBDP AAHL studying:
1. select a question and be told which topics it includes;
2. select a topic and see which questions include it;
3. see frequency analysis of all topics across all past papers.

This should help both teachers and students in revision. #ibmaths #aahl
Screenshot showing a tool where a past paper question is selected and the topics involved are displayed. A screenshot showing a tool where a topic is chosen and the past paper questions including this topic are displayed. A tool that analyses the topics in all past paper questions, and displays how many times each topic has appeared in past papers.

The Question Strip activity type is really useful for quick starters. Choose a topic and create questions, then choose the number of columns. Save on printing and easy to stick in books.

I love all the resources from @draustinmaths, they are always well thought out.

If you need more of these, you can create this type of activity with randomly generated questions on many topics on my site. Choose 'Codebreaker' as Activity Type.

I am quite chuffed with my new question type on the IB AAHL generator. Not so much for this particular question, but because I have managed to code it in a way that should allow me to do a lot more types on calculus.
